|
0:00:14
|
OK and we´re back.
|
|
0:00:19
|
So looking back at our task, our next task is
|
|
0:00:22
|
1.6 to trace the files or dealing with trace files
|
|
0:00:27
|
in general and the Web User Interface.
|
|
0:00:29
|
So we´re instructed to enable CUCM trace files
|
|
0:00:32
|
for Corporate Headquarter Phone 1 and 2 only
|
|
0:00:36
|
and a place to call to 911 to generate records to view.
|
|
0:00:41
|
OK, so we´ll switch back over
|
|
0:00:47
|
to our CUCMA.
|
|
0:00:52
|
Our serviceability actually I did want to come to CUCMA first just to check
|
|
0:00:58
|
and see our headquarter phone 1
|
|
0:01:01
|
and 2 what their MAC addresses were
|
|
0:01:05
|
and I´ll just take those down, copy those down in
|
|
0:01:10
|
notepad or textedit is what I´m using but in the lab you'll have notepad
|
|
0:01:20
|
and we´ll go back to serviceability
|
|
0:01:27
|
and we´ll go over to trace configuration
|
|
0:01:32
|
though were going to choose a server shouldn´t
|
|
0:01:34
|
matter which server because we are going
|
|
0:01:36
|
to apply to all nodes the service
|
|
0:01:39
|
group is going to be call manager services
|
|
0:01:43
|
and we specifically want to look at the call
|
|
0:01:45
|
manager service under the call manager services
|
|
0:01:51
|
redudant, we´re going to apply this to all nodes.
|
|
0:01:54
|
Ensure the traces on and the level it set to detailed
|
|
0:01:59
|
and we´re pretty much going to turn off, well
|
|
0:02:04
|
we´re going to unselected a number of the
|
|
0:02:15
|
the traces because we want to do device name
|
|
0:02:18
|
Based Trace Monitoring and we´re going to choose select devices
|
|
0:02:23
|
and we can actually use directory number
|
|
0:02:27
|
but you know just in case we want to
|
|
0:02:29
|
later reference that dn´s, sorry, the phones
|
|
0:02:34
|
MAC addresses certainly a good thing to have in mind, so we want 10001
|
|
0:02:42
|
and we´re going to trace that phone and we also want 1002
|
|
0:02:48
|
and we click trace on that phone if we go
|
|
0:02:50
|
back to 1001, let´s just ensure trace is
|
|
0:02:54
|
not checked again, so we want it to just, let´s say begin with 100
|
|
0:03:02
|
now, we can turn on trace for Corporate headquarter
|
|
0:03:05
|
phone 1 and 2 but not phone 3 and say save
|
|
0:03:15
|
OK? And now we´ll go ahead and save the status of this
|
|
0:03:25
|
upgraded completed on all nodes
|
|
0:03:27
|
so let´s go back to our task
|
|
0:03:31
|
we´re told to place a call to 911 to generate
|
|
0:03:34
|
records to view, so we´ll place to out headquarter
|
|
0:03:37
|
phone 1 and phone 2
|
|
0:03:40
|
let´s clear this screen off, make sure that´s
|
|
0:03:44
|
debug ISTN q931 is still set and it is
|
|
0:03:49
|
so we´ll go ahead and place call to 911
|
|
0:04:00
|
OK, we´ve got out first call from phone 1
|
|
0:04:09
|
second call from phone 2
|
|
0:04:14
|
OK?
|
|
0:04:16
|
we´ve got our calls and now we want to look
|
|
0:04:19
|
at the next task which tells us toread this traces
|
|
0:04:24
|
in fact let´s just go ahead and just so we
|
|
0:04:27
|
don´t get too much information in them
|
|
0:04:32
|
go ahead and apply on all nodes
|
|
0:04:35
|
turn traces off all together, for the servers
|
|
0:04:39
|
or for the service within the service group
|
|
0:04:44
|
and now we´ll go ahead and we´ll look at
|
|
0:04:46
|
the files via command line, so use the well actually
|
|
0:04:53
|
this files or this specific task is intsructing
|
|
0:04:57
|
us to use the SSH command line to tail the
|
|
0:05:01
|
end of the file which is going to show us
|
|
0:05:03
|
real time activity, so we do need to have this on
|
|
0:05:06
|
OK? So we´ll turn this back on
|
|
0:05:12
|
we already still have the device name
|
|
0:05:18
|
tracking on let´s just check, yes
|
|
0:05:23
|
to good, we´ve already had apply
|
|
0:05:28
|
OK, so we want to tail the end of the trace
|
|
0:05:30
|
file where the Corporate phone 1´s activity
|
|
0:05:32
|
will be seen and place the call from phone 1
|
|
0:05:35
|
to generate activity in real time, so let´s
|
|
0:05:37
|
switch over to our terminal client and now
|
|
0:05:42
|
this is something that we need to really
|
|
0:05:44
|
consider for any trace viewing which is
|
|
0:05:49
|
what server do we want to pull the files from
|
|
0:05:55
|
given everything that you´ve seen so far
|
|
0:05:57
|
do we want to pull the trace files from
|
|
0:05:59
|
the publisher or the subscriber?
|
|
0:06:05
|
correct, where the phones are registered
|
|
0:06:07
|
so if they´re currently registered
|
|
0:06:12
|
to .20 the subscriber then that´s where we want to pull
|
|
0:06:16
|
the information from, that´s correct
|
|
0:06:19
|
everyone´s answer is correct, OK
|
|
0:06:22
|
so we need to be over on the subscriber server
|
|
0:06:25
|
and we need to be looking at files so
|
|
0:06:28
|
start with the command file and first of all do
|
|
0:06:31
|
a file list to list certain files
|
|
0:06:35
|
the files that we want to list are part of active log
|
|
0:06:40
|
and then we have to specify the file to view
|
|
0:06:44
|
which could be in a sub directory, so now
|
|
0:06:47
|
we need to know the directory structure or
|
|
0:06:48
|
figure it out, so let´s do forward slash, enter
|
|
0:06:53
|
and that tells us files and or, in this case
|
|
0:06:56
|
there´s only directories, OK so we see CM
|
|
0:07:01
|
forward slash CM, forward slash what´s in
|
|
0:07:04
|
the next directory level then cdr repository
|
|
0:07:08
|
log Tftp data, trace okay
|
|
0:07:12
|
so let´s add and trace and in this is not
|
|
0:07:14
|
command completion, I can´t hit tab to complete
|
|
0:07:19
|
type this out manually or copy and paste
|
|
0:07:23
|
as recommended, so within the trace directory
|
|
0:07:26
|
I´ve got CUCM, that´s the sub service that
|
|
0:07:31
|
I want to be looking at and now I´ve
|
|
0:07:33
|
got either STI or STL
|
|
0:07:38
|
OK? Segment data later
|
|
0:07:42
|
So let´s look at, we can look at a little
|
|
0:07:44
|
bit of information from both, each have their
|
|
0:07:48
|
positives and negatives, pros and cons
|
|
0:07:51
|
and we always want to look at the highest
|
|
0:07:53
|
numbered file, that´s always going to be the latest file
|
|
0:07:57
|
so at the end of this we´re going to want
|
|
0:07:59
|
to copy and paste, don´t try to guess how
|
|
0:08:01
|
many zeros there are, count them
|
|
0:08:03
|
this file name, so now we´ve listed this file
|
|
0:08:07
|
that´s great, we know it´s there,we can even
|
|
0:08:10
|
do details about it, if we want to see when
|
|
0:08:13
|
was created, how big it is
|
|
0:08:16
|
OK, Is it growing in size keep hitting the
|
|
0:08:19
|
enter a couple of times, it doesn´t look
|
|
0:08:20
|
like it´s growing right now, mainly because we´re
|
|
0:08:23
|
only tracing 2 phones and they´re not doing anything
|
|
0:08:26
|
except every once in awhile sending some signaling back
|
|
0:08:31
|
OK, what we instead want to do is
|
|
0:08:35
|
get rid of the detail at the end
|
|
0:08:38
|
and go back and replace the word list
|
|
0:08:41
|
with we can either do view, it wasn´t what
|
|
0:08:45
|
we´re instructed to do, but we can look at view
|
|
0:08:47
|
hit e to go down and look at the end of the file
|
|
0:08:53
|
or what we were instructed to do was file
|
|
0:08:57
|
tail, ok, so tail is a unix command, I´m just
|
|
0:09:01
|
going to hit up and I´m going to
|
|
0:09:05
|
replace view with tail, tail is a unix command
|
|
0:09:09
|
and that will allow me to see the last
|
|
0:09:12
|
so many lines typically 10 or 20 of a file
|
|
0:09:17
|
so you can see that it didn´t return a command prompt
|
|
0:09:20
|
and I can´t hit enter anything else
|
|
0:09:22
|
I can hit Ctrl C to exit, but I can not do anything
|
|
0:09:28
|
much beyond that because it´s currently
|
|
0:09:31
|
and a real time trace method so we were told
|
|
0:09:34
|
to look for phone 1 and have it call 911
|
|
0:09:39
|
and again to generate the activity
|
|
0:09:41
|
so let´s, let me bring up my
|
|
0:09:47
|
our remote phone here for extension 1001
|
|
0:09:59
|
now, let take control that with refresh rate of let´s say 3
|
|
0:10:09
|
phone, go much better
|
|
0:10:17
|
tell it to refresh after 3 and so go ahead and make the call to 911
|
|
0:10:28
|
OK, now we expect that we´re seeing some live
|
|
0:10:31
|
Traced information behind here, let´s ctrl C alt
|
|
0:10:34
|
and let´s just make sure the file list that we
|
|
0:10:37
|
still have the latest file, it could have rolled over to a new file
|
|
0:10:41
|
right now, doesn´t look like it has rolled over to the file
|
|
0:10:46
|
let´s look at STL
|
|
0:11:01
|
that is activated, failed trace on
|
|
0:11:12
|
number begins at 1000
|
|
0:11:20
|
1001 is selected for Corporate headquarter phone, save
|
|
0:11:50
|
OK, well we´re not seeing any information well
|
|
0:11:53
|
so be a good thing to troubleshoot so let´s go ahead and
|
|
0:12:08
|
turn off device name tracking
|
|
0:12:12
|
and all phone device trace, let´s leave that on
|
|
0:12:22
|
gateway trace as well
|
|
0:12:29
|
by the all nodes, let´s just go ahead and specifically
|
|
0:12:32
|
we call out 20, for whatever reason.
|
|
0:12:46
|
It looks like I might not have been logged in
|
|
0:12:48
|
eventhough it was taking my command
|
|
0:12:52
|
so let´s just go ahead and enable it specifically
|
|
0:12:54
|
here just in case it was not
|
|
0:12:57
|
replicating that applied to all nodes properly
|
|
0:13:01
|
OK
|
|
0:13:07
|
found number 3, now we have found number 4
|
|
0:13:15
|
file number 4 and let´s try this call again
|
|
0:13:23
|
they´ll not seeing any live trace, does anyone have a
|
|
0:13:32
|
any idea what might be going on here?
|
|
0:13:59
|
there we go, we´re getting STL information
|
|
0:14:01
|
we weren´t getting any STI information
|
|
0:14:07
|
OK?
|
|
0:14:10
|
well we have to troubleshoot why STI wasn´t coming
|
|
0:14:12
|
through but now that we have STL, let´s
|
|
0:14:15
|
take a look at this and it´s really useful if you
|
|
0:14:16
|
can have a wide screen because this
|
|
0:14:19
|
lines get all, all mess up a little bit
|
|
0:14:24
|
but we´re seeing MGCP information, that´s the name
|
|
0:14:28
|
of the MGCP headquarter gateway router.
|
|
0:14:32
|
So we know we have gateways working, let´s go ahead and
|
|
0:14:37
|
go back and enable or disable, all gateways from being trace
|
|
0:14:43
|
to verify that our phones were
|
|
0:14:50
|
that´s interesting, I got an error logging in
|
|
0:14:52
|
and there might have been a
|
|
0:14:56
|
are registered to the sub, if this keeps up I might
|
|
0:15:01
|
clear them from the sub and register them to the pub.
|
|
0:15:05
|
All phones detailed okay.
|
|
0:15:11
|
Back.
|
|
0:15:15
|
Clear the screen a little bit and redial the number
|
|
0:15:22
|
not seeing the phone information alone
|
|
0:15:27
|
very interesting, alright so I´m going to go ahead
|
|
0:15:29
|
and bring up the pub at this point and I´m going to go ahead and
|
|
0:15:34
|
from serviceability, feature services, stop the subscriber CUCM service,
|
|
0:15:50
|
that way we know that everything will go over to the publisher
|
|
0:15:55
|
and we know that we can troubleshoot on the publisher, so I´ll go ahead and
|
|
0:15:59
|
all that stopping, I already have the pub pulled up.
|
|
0:16:02
|
So let´s do a show, file list, active log
|
|
0:16:10
|
forward slash cm forward slash trace
|
|
0:16:14
|
forward slash ccm and then sti
|
|
0:16:21
|
that file number 3 and 4.
|
|
0:16:28
|
We´ll place that in there, replace list
|
|
0:16:33
|
view, but I have to space log.
|
|
0:16:40
|
OK, We got information in there we can see
|
|
0:16:44
|
that a number of devices actually just registered.
|
|
0:16:53
|
Now we´re place view with tail.
|
|
0:17:01
|
OK, and let´s go check to make sure those
|
|
0:17:04
|
phones are now registered to the pub rather than sub.
|
|
0:17:06
|
They are all registered to the pub.
|
|
0:17:10
|
Go back to serviceability trace.
|
|
0:17:14
|
and
|
|
0:17:19
|
manager
|
|
0:17:25
|
and detailed let´s just do all phones just
|
|
0:17:28
|
for the moment just we get any sort of information.
|
|
0:17:37
|
And bring up our log and bring up
|
|
0:17:45
|
phone and redial and we can´t redial because it
|
|
0:17:50
|
just restarted, so it doesn´t have any.
|
|
0:17:55
|
Here we go, now we´re getting information.
|
|
0:17:58
|
So the stimulus 9 and 1,
|
|
0:18:07
|
call, now at some point here it actually stop transmitting data.
|
|
0:18:15
|
We saw the, send the station off hook on line 1, new call,
|
|
0:18:22
|
send the signal to the device F1DE
|
|
0:18:27
|
which is our first phone, phone 1.
|
|
0:18:35
|
OK, that station´s off hook,
|
|
0:18:40
|
set the ringer mode to off, speaker mode to on.
|
|
0:18:45
|
Look like we got as far as getting a, set the lamp mode
|
|
0:18:50
|
to 2, stimulus 9 and 1 and then set up the call.
|
|
0:18:57
|
So we began seeing information and it stopped,
|
|
0:19:00
|
so instead of doing this let´s look at a
|
|
0:19:07
|
rolled to another file,
|
|
0:19:09
|
that´s right where it stops did it roll to another file?
|
|
0:19:19
|
Didn´t rolled to another file, looks like we have some
|
|
0:19:21
|
sort of an issue with writing records to the
|
|
0:19:26
|
writing trace file records to the system because that´s where
|
|
0:19:37
|
tops. Let´s look at SDL instead,
|
|
0:19:47
|
activate SDL which can be very useful.
|
|
0:20:00
|
Call control trace
|
|
0:20:26
|
place
|
|
0:20:55
|
OK
|
|
0:21:10
|
Alright, let´s try the call again, there we go.
|
|
0:21:18
|
Take a deal of mgcp information, here we are.
|
|
0:21:23
|
Alright, let me take off the mgcp
|
|
0:21:29
|
gateways.
|
|
0:21:36
|
Turn off the database signaling.
|
|
0:21:46
|
OK, clear the fields, try to call again
|
|
0:21:53
|
here we go.
|
|
0:21:58
|
OK, so now we have information we can look at
|
|
0:22:03
|
and a lot of information at that, so
|
|
0:22:08
|
and again it´s very helpful if
|
|
0:22:11
|
we don´t have to
|
|
0:22:15
|
view this in such a small screen we only have
|
|
0:22:19
|
1024 by 768 here just for the sake of the online
|
|
0:22:26
|
seminar and optimizing for everyone´s screen.
|
|
0:22:31
|
I´m just scrolling through here.
|
|
0:22:33
|
What we can do is actually, let me just go ahead and
|
|
0:22:37
|
ctrl C out of this and what we can do is instead of tailing,
|
|
0:22:41
|
we mentioned that we can search.
|
|
0:22:47
|
And we can search for a specific regular expression
|
|
0:22:53
|
or search rings, so let´s actually search for
|
|
0:22:59
|
name of our device and we can see a lot of information
|
|
0:23:05
|
regarding this device. So here we see,
|
|
0:23:10
|
the station, the partition that the dn is in of course
|
|
0:23:15
|
this is in a pkid, Primary Key Database format which is
|
|
0:23:22
|
maybe not the most hepful in this particular case.
|
|
0:23:27
|
Sti is what I´d rather show you, rather than Sdl.
|
|
0:23:36
|
Sdl can be certainly useful in certain situations.
|
|
0:23:39
|
Let´s see if Sti has turn up anything by now.
|
|
0:23:45
|
If it´s actually is recorded in this file list, active log Sti.
|
|
0:24:18
|
And here´s certainly some information
|
|
0:24:27
|
and space until we get all the way to the end of the file.
|
|
0:24:43
|
OK, here we go, here is more of what we want to see,
|
|
0:24:46
|
So here´s our MAC address, our device name,
|
|
0:24:50
|
here is the calling party name,
|
|
0:24:56
|
voicemail box, the called party name, doesn´t have one
|
|
0:25:01
|
called party number.
|
|
0:25:07
|
The original called party 911 the reason you see +911.
|
|
0:25:11
|
We´ll get in to that in the dial plan module that´s because my
|
|
0:25:14
|
translation pattern added a plus
|
|
0:25:17
|
or E164 reason that we can talk about
|
|
0:25:21
|
last redirecting party isn´t so important, let´s actually
|
|
0:25:25
|
go back up a little bit more because I want to show you
|
|
0:25:30
|
specifically, here
|
|
0:25:37
|
Little hard for me to read, I have to reformat this page.
|
|
0:25:45
|
OK, there we go
|
|
0:25:48
|
They might not be able to see the end there,
|
|
0:25:50
|
but it will be a little bit more
|
|
0:25:54
|
easy to read in sense that most of the lines will
|
|
0:25:57
|
start with the proper information. It´s really hard to read
|
|
0:26:00
|
when you have to look at it, in that kind of a
|
|
0:26:03
|
multiple line wrap or wrap situations.
|
|
0:26:10
|
We still can only see a little bit of it at a time.
|
|
0:26:17
|
But we should be able to try tailing it now, rather than.
|
|
0:26:43
|
Whatever reason, it just stop on the tail right there, I mean
|
|
0:26:48
|
the stand alone cluster MGCP end point did not just in right there.
|
|
0:26:53
|
So for whatever reason, we´re having a little bit of an issue
|
|
0:26:55
|
reading and writing real time from the database.
|
|
0:26:59
|
In real time command line, which kind of defeats the
|
|
0:27:03
|
purpose of me showing it to you as a speed tip.
|
|
0:27:05
|
So I´m really sorry that this is, kind of happenings
|
|
0:27:09
|
particular instance, it normally works for me quiet well.
|
|
0:27:15
|
To view the trace files from command line,
|
|
0:27:17
|
but our next task will certainly go overviewing them
|
|
0:27:20
|
from the RTMT and Real time and in Search.
|
|
0:27:23
|
OK, so we accomplished this sort of, but
|
|
0:27:29
|
the benefit of the speed I assumed, probably got lost.
|
|
0:27:36
|
Revil,I saw your hand raised. Did you have a question?
|
|
0:27:42
|
Do I know if we have sftp in the lab so that
|
|
0:27:46
|
we can download traces using file yet?
|
|
0:27:50
|
I don´t think that you will, you do have an SSH client
|
|
0:27:56
|
on your xp work station, but I don´t believe that you have sftp.
|
|
0:28:01
|
What you do have is,
|
|
0:28:03
|
what we´re going in to next which is the RTMT.
|
|
0:28:07
|
OK, so the Real time monitoring tool,
|
|
0:28:09
|
we can use to collect the files and
|
|
0:28:15
|
gather information about them. So let´s go ahead and
|
|
0:28:19
|
spun the RTMT and break that up.
|
|
0:28:27
|
Now the reason
|
|
0:28:32
|
that you definitely do have RTMT
|
|
0:28:39
|
in the lab is that
|
|
0:28:51
|
loads here
|
|
0:28:58
|
You know what, I think might bring up my native.
|
|
0:29:03
|
Faster.
|
|
0:29:09
|
Press.
|
|
0:29:21
|
OK, so the reason that I know that we do have RTMT
|
|
0:29:24
|
in the lab is that from the
|
|
0:29:32
|
from the web interface, the CUCM admin interface.
|
|
0:29:37
|
We can go to application plug ins
|
|
0:29:41
|
and we actually find that it is
|
|
0:29:47
|
of limited it to just start TMT, but that´s fine
|
|
0:29:51
|
it should be down at the bottom once this refreshes.
|
|
0:29:58
|
We do have it available, right here for windows.
|
|
0:30:01
|
OK, so we can download and install it however,
|
|
0:30:04
|
I can also tell you that it´s already installed for you
|
|
0:30:07
|
on your xp desktop. Any applications, any tools
|
|
0:30:12
|
that are available native within the
|
|
0:30:15
|
services and servers that are listed on the blueprint,
|
|
0:30:18
|
such as any of the five servers CUCM pub
|
|
0:30:22
|
and sub being 2 CUPS UCCX,
|
|
0:30:25
|
and unity connection being the other 3.
|
|
0:30:28
|
Anything that´s native within there, such as
|
|
0:30:31
|
for instance we mentioned earlier, dialed number analyzer
|
|
0:30:33
|
and the serviceability tools, once we activated the services,
|
|
0:30:38
|
dialed number analyzer is available as a tool that
|
|
0:30:40
|
you can use in the actual CCI lab
|
|
0:30:44
|
and at times it can be useful.
|
|
0:30:50
|
Let´s go back to RTMT and let´s go to trace and log central
|
|
0:30:56
|
and we can look at a real time trace.
|
|
0:30:59
|
So although, whenever we can´t pull SFTP
|
|
0:31:02
|
we can collect and remote browse the files .
|
|
0:31:07
|
Can view real time data?
|
|
0:31:11
|
Collect a node, we shut down the subscriber.
|
|
0:31:15
|
Though we´ll choose CUCM.
|
|
0:31:20
|
Call Manager and we´ll look for STI
|
|
0:31:25
|
and hope that maybe it will
|
|
0:31:27
|
pull a little bit cleaner in this environment.
|
|
0:31:44
|
Currently waiting for the final update.
|
|
0:31:49
|
Now, if there really is a problem
|
|
0:31:52
|
with the server reading and writing from the disk
|
|
0:31:56
|
and the database then there could be just as
|
|
0:32:00
|
much of an issue reading the trace file from here.
|
|
0:32:04
|
It´s possible that we want to reboot the publisher server
|
|
0:32:07
|
so if we have the same issue that we had
|
|
0:32:10
|
from command line,
|
|
0:32:11
|
which I actually have seen before,
|
|
0:32:14
|
but it was, I haven´t seen it on
|
|
0:32:16
|
701, I´ve seen it on 70.
|
|
0:32:20
|
Then 700 I should say, then in that case
|
|
0:32:26
|
we might just move on to the next task
|
|
0:32:28
|
and come back to this because it looks like
|
|
0:32:30
|
we are having an issue pulling any information.
|
|
0:32:34
|
Let´s try life call and see if anything goes up.
|
|
0:32:42
|
Here we go.
|
|
0:32:45
|
Now we´re seeing the information.
|
|
0:32:51
|
Go ahead and turn down the volume
|
|
0:32:53
|
and let that ring rather than.
|
|
0:32:58
|
OK, so here is exactly what we wanted to see,
|
|
0:33:03
|
going off hook, setting the ring mode, speaker mode.
|
|
0:33:11
|
OK, here comes the dialed number 911, line instance 1.
|
|
0:33:20
|
They can search within this live call which
|
|
0:33:25
|
is live debug which is very nice.
|
|
0:33:28
|
You see the calling party name
|
|
0:33:31
|
This also we don´t have any issues with the line wrap.
|
|
0:33:36
|
OK, so let´s look for
|
|
0:33:43
|
device.
|
|
0:33:52
|
See that it´s searching for S, so slot 0,
|
|
0:33:55
|
Subunit 0, DS 1 so t10 on Corporate headquarters
|
|
0:34:01
|
to the MGCP end point to make the call.
|
|
0:34:05
|
So the call is attempting to go up the gateway there
|
|
0:34:12
|
and then we see information back and
|
|
0:34:14
|
forth from the MGCP end point.
|
|
0:34:27
|
If we just want to see information about this call,
|
|
0:34:30
|
we can enter our search to in here
|
|
0:34:39
|
and it will highlight it for us.
|
|
0:34:47
|
And we can finally answer the phone if we like.
|
|
0:34:59
|
OK, we saw the softkey event to turn on mute there
|
|
0:35:08
|
and we see more MGCP information because
|
|
0:35:11
|
at this point the call is
|
|
0:35:16
|
is proceeding through that MGCP gateway.
|
|
0:35:18
|
Want to go ahead and tear the call down.
|
|
0:35:23
|
OK, to answer your question, Yaser
|
|
0:35:27
|
you said how can I repeat
|
|
0:35:29
|
how I started the real time monitor? Absolutely
|
|
0:35:35
|
So on the real time monitoring tool,
|
|
0:35:38
|
we go to Trace and Log central
|
|
0:35:41
|
and then from there we expanded Real Time Trace
|
|
0:35:44
|
double click on View Real Time data,
|
|
0:35:47
|
selected the node so I´ve shut down
|
|
0:35:49
|
the CUCM service on the subscriber.
|
|
0:35:51
|
So I know that all my phones are registered to the publisher.
|
|
0:35:55
|
Choose next, the product of CUCM,
|
|
0:35:58
|
the service being call manager,
|
|
0:36:04
|
and then the file type being STI, we can also look at SDL
|
|
0:36:08
|
or database information, if that´s what we´re looking at
|
|
0:36:12
|
or wanted to view, it pulls up another window.
|
|
0:36:15
|
I bring it over to the viewable window and then we,
|
|
0:36:20
|
this is a Real time.
|
|
0:36:24
|
Download at this point.
|
|
0:36:28
|
Now waits for the filed update
|
|
0:36:30
|
and there we´ve got information about the call.
|
|
0:36:38
|
If we wanted to search for
|
|
0:36:41
|
the device name, we could also do that.
|
|
0:36:43
|
It doesn´t allow paste though, it doesn´t look like, no.
|
|
0:36:47
|
So SEP, well actually let´s just key in
|
|
0:36:51
|
F1DE, Foxtrot 1 Delta Echo
|
|
0:37:01
|
and there we see the device name, the last
|
|
0:37:05
|
four of the MAC address highlighted wherever we are
|
|
0:37:09
|
speaking or receiving information
|
|
0:37:11
|
to or from the phone respectively.
|
|
0:37:33
|
OK.
|
|
0:37:36
|
Where did I download RTMT for MAC?
|
|
0:37:41
|
From a friend, but I´m sure I could probably make that available.
|
|
0:37:47
|
Actually, a friend of mine, custom wrote it.
|
|
0:37:54
|
Just Java.
|
|
0:37:57
|
OK, so we´ve look at them in Real Time
|
|
0:38:00
|
and we view search we haven´t use search in non-real time though,
|
|
0:38:04
|
so let´s take a look at search with non-real time, as our Task 1.9.
|
|
0:38:13
|
OK? So let´s go to
|
|
0:38:17
|
browse the trace files
|
|
0:38:21
|
and we want to browse, let´s browse call manager
|
|
0:38:26
|
from all servers and specifically the
|
|
0:38:39
|
call manager realm.
|
|
0:39:00
|
Pulling information.
|
|
0:39:03
|
OK, I have nodes, sub and pub.
|
|
0:39:06
|
So I open up pub, grab CUCM the remote browser is ready
|
|
0:39:11
|
the result tells us call manager and sdi.
|
|
0:39:15
|
Double click there and I´ve got my,
|
|
0:39:18
|
I´ll just collapse this over here I´ve got my last 2 files.
|
|
0:39:22
|
So I can open that, I´ll just use my generic viewer.
|
|
0:39:30
|
And here I´ve got the non-real time
|
|
0:39:35
|
file that I can certainly search through,
|
|
0:39:40
|
just I was doing earlier
|
|
0:39:42
|
so I don´t think it will still allow copy and paste, doesn´t.
|
|
0:39:46
|
So 0001 that was 001 Bravo 5452 and Foxtrot 1 Delta Echo.
|
|
0:40:13
|
And again this file´s pretty big, but we can
|
|
0:40:16
|
scroll down and see highlighted in red
|
|
0:40:19
|
Unfortunately, this doesn´t do what the,
|
|
0:40:27
|
this doesn´t quite do what Cisco VLT does.
|
|
0:40:32
|
Is anyone familiar with the VLT?
|
|
0:40:35
|
I´ll go ahead and pull that up here real quick.
|
|
0:40:46
|
Voice Log Translator is really nice.
|
|
0:40:52
|
So if I tell it to open a log file
|
|
0:40:59
|
that I have already downloaded, I do have to already downloaded it
|
|
0:41:05
|
and they can sit here and
|
|
0:41:08
|
show me specific timestamps device IPs. What message was sent.
|
|
0:41:14
|
All sorts of really good information about
|
|
0:41:18
|
and you can use filters and it will only show you
|
|
0:41:21
|
specifically what it is that you want,
|
|
0:41:23
|
filter by IP or protocol or whatever you like
|
|
0:41:28
|
that´s really really useful tool.
|
|
0:41:30
|
This is the translator tool. The Voice Log translator however,
|
|
0:41:35
|
this is separate download from cisco.com.
|
|
0:41:38
|
For whatever reason it was not included in the plug-ins
|
|
0:41:41
|
and it´s still not even in 8,
|
|
0:41:44
|
it´s still not included in the plug-ins for
|
|
0:41:46
|
whatever reason just completely battles me, I´m not sure.
|
|
0:41:50
|
but because it´s not in the plug-ins, it means that you
|
|
0:41:52
|
will not have it available to you in the real lab either.
|
|
0:41:56
|
It´s a great tool for real life you should certainly
|
|
0:41:59
|
download it and use it but in the lab, it unfortunately will not be available.
|
|
0:42:09
|
OK? So look back at our next task.
|
|
0:42:16
|
So we´ve look that trace files real time from RTMT and search in non-real time.
|
|
0:42:24
|
Now, let´s look at RIS from command line,
|
|
0:42:28
|
so just something that we can do very quickly
|
|
0:42:31
|
is look the pub and do a show, risdb.
|
|
0:42:41
|
Now we can do a list or a query.
|
|
0:42:46
|
So list, I can list the individual tables
|
|
0:42:49
|
that I may be able to pull from phone, phone extension
|
|
0:42:54
|
region, device pool, etcetera.
|
|
0:42:59
|
In this case, we were told to check how many IP phones
|
|
0:43:02
|
are registered via the pub or sub command line depending on
|
|
0:43:05
|
which is the active CPE at this point of pub is.
|
|
0:43:08
|
So we need to do show risdb, query, and we want a query phone.
|
|
0:43:19
|
OK, I know it was phone because these are the available options
|
|
0:43:22
|
that I have to query and I already hit seen phone up there.
|
|
0:43:27
|
So, we now see and they do have columns at the CSV file however,
|
|
0:43:33
|
the columns aren´t exactly lined up.
|
|
0:43:37
|
But we can see roughly that we´ve got
|
|
0:43:40
|
total phones are 7 and total registered are 7.
|
|
0:43:45
|
So I´ve got 7 phones and they´re all registered.
|
|
0:43:48
|
I can see their IP addresses.
|
|
0:43:51
|
I can see information about them, what protocols they are
|
|
0:43:54
|
registered status, reg.
|
|
0:43:57
|
Is there a user ID associated, various things, device model
|
|
0:44:02
|
things like that including their description.
|
|
0:44:06
|
OK, so just a real quick tool we could
|
|
0:44:08
|
do something beyond just the task, we could show
|
|
0:44:11
|
risdb for, let´s see, what was one of our,
|
|
0:44:16
|
well actually query is the next thing we need.
|
|
0:44:19
|
And what was one of the other thing? Let´s do gateway.
|
|
0:44:24
|
They paste and gateway and I can see that I´ve got
|
|
0:44:28
|
3 registered gateways
|
|
0:44:30
|
and gives me all the information about them.
|
|
0:44:35
|
Show risdb list again,
|
|
0:44:40
|
and maybe I can take a look at phone extension for instance.
|
|
0:44:47
|
Go risdb, query, phone extension.
|
|
0:44:53
|
And I can see what phone IP addresses and
|
|
0:44:57
|
SEP MAC adresses are registered to which
|
|
0:45:00
|
dn´s or rather which dn´s are registered to which MAC adresses.
|
|
0:45:04
|
OK, so just a couple quick things that I can do
|
|
0:45:08
|
to see very quick useful information.
|
|
0:45:14
|
Now this is going to be one of the most useful things in your lab.
|
|
0:45:19
|
Is the perfmon from either command line or RTMT, so performance monitor.
|
|
0:45:24
|
Here we´re told to, how much total bandwidth
|
|
0:45:27
|
and how much available bandwidth there is
|
|
0:45:30
|
for both the Corporate Headquarter and Branch2 sites when no calls are active.
|
|
0:45:35
|
And then we´re instructed to place a call
|
|
0:45:37
|
from the Corporate Headquarter Phone 1 to Branch2
|
|
0:45:40
|
Phone 1 and recheck both of the statistics.
|
|
0:45:44
|
OK, so back on the command line.
|
|
0:45:46
|
We´re now going to do show perf, query.
|
|
0:45:52
|
Actually, before we do that,let´s go back to show perf list, clas or classes
|
|
0:46:00
|
and we really only want to take a look at the call manager classes
|
|
0:46:05
|
though, what we were told to deal with?
|
|
0:46:08
|
Total band width is available, what is the sound like?
|
|
0:46:13
|
When the call is active or when the call is not active.
|
|
0:46:16
|
What is that sound like we´re talking about?
|
|
0:46:20
|
Anyone?
|
|
0:46:23
|
Locations, exactly correct.
|
|
0:46:25
|
So we´re going to search for locations and there it is,
|
|
0:46:28
|
it´s called Cisco locations. Alright, so
|
|
0:46:34
|
By the way the reason that a lot of these say
|
|
0:46:37
|
Cisco before them is all this
|
|
0:46:40
|
performance monitor statistics used to be included
|
|
0:46:43
|
in windows perfmon tool or performance monitor tool
|
|
0:46:49
|
and so they had it differentiate of course
|
|
0:46:51
|
from some microsoft type.
|
|
0:46:55
|
Back in the call manager 2, 3 and 4 days.
|
|
0:46:59
|
So now we´re going to do instead of show perf list classes,
|
|
0:47:03
|
we´re going to do show perf, query, class
|
|
0:47:08
|
and we of course need to double quotes
|
|
0:47:13
|
and here we´ve got the information that we need
|
|
0:47:16
|
for all of our sites. Now we´ve got a lot of information here.
|
|
0:47:22
|
First of all, all the information for Hub None
|
|
0:47:26
|
L1 Branch1, and then L Branch 2, or Location Branch2
|
|
0:47:31
|
and we see band width available, band width maximum,
|
|
0:47:36
|
now looks like everything´s set to zero right now.
|
|
0:47:40
|
So we actually need to go change something before
|
|
0:47:43
|
we can actually have any usable information here.
|
|
0:47:52
|
So we´ve got Hub None which is going to stay at 0 and
|
|
0:47:56
|
we´re going to revisit and talk about QOS of course, but
|
|
0:48:01
|
audio band width will put to, I don´t know
|
|
0:48:04
|
multiples of 24 for g729, let´s just say two calls.
|
|
0:48:10
|
OK, for Branch1, I´m not sure why I updated
|
|
0:48:12
|
that because we´re only supposed to be
|
|
0:48:14
|
interacting between headquarters and Branch 2.
|
|
0:48:19
|
And you know what? Let´s just for the sake of this demonstration
|
|
0:48:23
|
go ahead and make Hub_None although, this is not the recommended pratice.
|
|
0:48:28
|
Let´s just go ahead and set that to 48 as well.
|
|
0:48:30
|
So two calls in or out of every site.
|
|
0:48:33
|
Update was successul, but it didn´t actually keep.
|
|
0:48:39
|
as it´s Hub none. Alright, so we´re just going to
|
|
0:48:42
|
need to create a new site here, it´s actually just
|
|
0:48:50
|
copy this site, we´ll call it temp headquarters.
|
|
0:48:58
|
Save it and we´re going to use BAT
|
|
0:49:03
|
to go ahead and update our phones based on a query
|
|
0:49:09
|
OK? We talked about being able to do this,
|
|
0:49:12
|
we have to modify 3 phones. This is the quickest way.
|
|
0:49:15
|
And we´ll say if the directory number begins with 1
|
|
0:49:18
|
then we want that to be a part of our query.
|
|
0:49:20
|
Good, there´s are 3 headquarter phones.
|
|
0:49:25
|
and now when you´re done I want you
|
|
0:49:27
|
to restart the phones, not reset them.
|
|
0:49:31
|
OK? Log out if they were log in to extension mobility,
|
|
0:49:35
|
but we don´t have any of that going on.
|
|
0:49:36
|
And I want to set location for each of these,
|
|
0:49:39
|
to Temp headquarter, so I want to check that.
|
|
0:49:43
|
By the way if your using bat to update anything
|
|
0:49:46
|
sometimes you see 2 checkboxes like this.
|
|
0:49:49
|
The reason for 2 checkboxes,
|
|
0:49:51
|
well the first one is do I want to affect this field?
|
|
0:49:55
|
The second is, is this a checkbox who use device
|
|
0:49:59
|
calling party transformation CSS, turned on
|
|
0:50:03
|
check or turned off
|
|
0:50:05
|
I say that´s the reason sometimes you´ll see 2 checkbox
|
|
0:50:08
|
Don´t forget to check the checkbox next to the field
|
|
0:50:11
|
you´re setting because everything else you´re saying
|
|
0:50:13
|
leave alone, leave it as it was
|
|
0:50:16
|
And we´re run immediately, update the phones for headquarter locations.
|
|
0:50:24
|
Submit it. 0 records found, job request submitted.
|
|
0:50:30
|
Let´s go check the scheduler
|
|
0:50:35
|
and update phones headquarter location is completed,
|
|
0:50:39
|
for those should be in the proper location and my phone is resetting right now,
|
|
0:50:46
|
is registering
|
|
0:50:56
|
and there it is, it's back.
|
|
0:50:59
|
OK, so back to the command line, so let´s run this command again.
|
|
0:51:05
|
Now we see that we have a number of 48 fields
|
|
0:51:08
|
so were going to be calling between Branch2
|
|
0:51:11
|
helpful with there at the bottom
|
|
0:51:13
|
Branch2 and temp headquarters. OK, so bandwidth available is 48 currently
|
|
0:51:20
|
and then the maximum, it can never be this 48.
|
|
0:51:23
|
OK, so to answer our task question, how much total bandwidth?
|
|
0:51:29
|
An available bandwidth is there for both corporate and Branch2.
|
|
0:51:34
|
Well, we have for corporate 48 and 48 for the first question
|
|
0:51:40
|
and then for branch, first and second question really
|
|
0:51:43
|
and then for Branch2 48 and 48.
|
|
0:51:45
|
OK, so now, now we´re going to place a call.
|
|
0:51:53
|
I´ll go ahead and bring up my next phone,
|
|
0:51:58
|
I can answer the call,
|
|
0:52:04
|
and we´re told to go between Branch1 or headquarter
|
|
0:52:07
|
and Branch2, so let´s bring up maybe 3002
|
|
0:52:11
|
3001, I think we were told phone numer 1.
|
|
0:52:15
|
and refresh it every 3 seconds, sounds good, control it.
|
|
0:52:26
|
OK, so now we´ll place a call, the 3002.
|
|
0:52:36
|
Mute here.
|
|
0:52:42
|
I called 3002 rather than 3001, user error there.
|
|
0:52:50
|
OK, new call 3001 now the call is ringing in.
|
|
0:53:07
|
Call.
|
|
0:53:10
|
Test, yes, it´s connected
|
|
0:53:15
|
OK, we´ve got mute on.
|
|
0:53:18
|
And now we can see that for Branch2 maximum
|
|
0:53:22
|
bandwidth is of course still 48, but available is 24.
|
|
0:53:26
|
And also for headquarters,
|
|
0:53:29
|
so this actually goes to part of what we would
|
|
0:53:31
|
talk about with locations based CAC is that
|
|
0:53:35
|
bandwidth is decremented from both the calling and the called party.
|
|
0:53:43
|
Always decremented from both now if one side,
|
|
0:53:45
|
has like hub-none has unlimited then
|
|
0:53:49
|
it´s of course decremented from 0 which is still
|
|
0:53:53
|
infinity you know still infinite band width
|
|
0:53:56
|
which is the reason that I set up a Tempheadquarter
|
|
0:53:58
|
location to illustrate that it´s decremented from both
|
|
0:54:02
|
calling and called, original and destination location.
|
|
0:54:09
|
OK, so we´ve done that, hang up the call
|
|
0:54:14
|
check the bandwidth again, everything´s back to 48
|
|
0:54:18
|
all is good there and we´ve met the requirement.
|
|
0:54:23
|
Now let´s look at that same statistic via perfmon through RTMT.
|
|
0:54:29
|
Well we could look at the same statistic,
|
|
0:54:31
|
actually let´s look at a different one, as for the task.
|
|
0:54:35
|
So determine if there are any active music on
|
|
0:54:37
|
hold streams either unicast or multicast on the CUCM sub or pub server
|
|
0:54:44
|
place a call from Corporate Headquarter Phone 1 to
|
|
0:54:46
|
to Branch2 phone 1. Of the Corporate phone,
|
|
0:54:49
|
place the Branch2 on hold and then recheck the statistics
|
|
0:54:54
|
and determine from these statistics if the call is
|
|
0:54:57
|
either unicast or if it is multicast.
|
|
0:55:02
|
OK, so now we´re going to look at perfmon from the RTMT.
|
|
0:55:09
|
Some things like logs and traces are probably
|
|
0:55:13
|
easier from RTMT, some things like what we see here,
|
|
0:55:19
|
Performance monitor statistics
|
|
0:55:21
|
are probably going to be easier from command line
|
|
0:55:24
|
in some regards, just depends on
|
|
0:55:26
|
what you like to see and what you like to use.
|
|
0:55:28
|
So we click on performance over here on the left,
|
|
0:55:31
|
go ahead and collapse this, now that we have what we want
|
|
0:55:34
|
I opened up 177 1 10 10
|
|
0:55:38
|
Why? Beacause our phones are still registered.
|
|
0:55:43
|
.10 so I would open up whichever servers folder
|
|
0:55:48
|
the phones are registered too
|
|
0:55:50
|
and I´m going to want to pull up the MOH Device.
|
|
0:55:59
|
And I was told to determine if there any active music on hold streams
|
|
0:56:07
|
unicast or multicast. So let´s grab not highest active, that was the peak,
|
|
0:56:13
|
but multicast resource active.
|
|
0:56:17
|
And do I want it for 2 and or 3? Now remember,
|
|
0:56:22
|
my CUCM sub server has the call manager service stop
|
|
0:56:26
|
however, that doesn´t mean it´s IP voice
|
|
0:56:29
|
me to streaming up service is stop.
|
|
0:56:32
|
So I will need to add both of them to determine.
|
|
0:56:36
|
OK, it´s only going to let me do one. I can add 1, then I can add the other
|
|
0:56:45
|
resources available, that´s not so much
|
|
0:56:48
|
what I´m interested in and then unicast resources
|
|
0:56:52
|
that´s total, I want active.
|
|
0:56:55
|
So 2 and _3 which is my sub,
|
|
0:57:00
|
so now I´ve got multicast pub, multicast sub, unicast pub, unicast sub
|
|
0:57:07
|
and the nice thing here is these are in real time.
|
|
0:57:10
|
I can change monitoring properties and how fast they should
|
|
0:57:15
|
a resample, how many data points to show on the chart, things like that
|
|
0:57:19
|
The problem is there not,they're in graf format.
|
|
0:57:23
|
So the nice things is that they are real time,
|
|
0:57:27
|
I don´t necessarily like graph as much as I like just hard
|
|
0:57:31
|
numerical values, like this.
|
|
0:57:34
|
But with the command line you have to continue to hit up enter
|
|
0:57:38
|
to see the changes, there´s no real time information flowing.
|
|
0:57:42
|
So again, both have their plus and minuses
|
|
0:57:45
|
So now we´re told to place a call from Corporate Phone1
|
|
0:57:48
|
to Branch2 phone1 and then have Corporate Branch2 put on hold
|
|
0:57:53
|
and determine, first of all recheck the statistics and determine
|
|
0:57:56
|
if the call, the music on hold is multicast or unicast.
|
|
0:58:00
|
Alright? So we set everything up yesterday,
|
|
0:58:03
|
so that it should be mulicast, but we´ll take a look.
|
|
0:58:09
|
Alright? So let´s place the call.
|
|
0:58:15
|
Where are we told to go from Corporate to Branch2?
|
|
0:58:18
|
Good we´ve already got that up.
|
|
0:58:27
|
Answer, put it on mute. and we lost the refresh here, there we go.
|
|
0:58:33
|
OK, and we´ll put this call on hold.
|
|
0:58:42
|
A little quiet, probably can´t hear it when we turned it up.
|
|
0:58:49
|
And our RTMT shows that we have a unicast resource active
|
|
0:58:56
|
on MOH_2.
|
|
0:58:59
|
So we have to deduced unicast, music on hold
|
|
0:59:05
|
rather than multicast and it´s all in the publisher
|
|
0:59:08
|
and we´ve done that from the RTMT, Performance Monitor Tools.
|
|
0:59:17
|
Resume that.
|
|
0:59:21
|
Mute on both.
|
|
0:59:23
|
And why isn´t multicast? Well we can troubleshoot out if we want
|
|
0:59:27
|
probably because we tore down the cluster and
|
|
0:59:30
|
rebuilt it from CSV and there´s probably something
|
|
0:59:32
|
that we haven´t set yet so very potentially on the gateways
|
|
0:59:37
|
OK? So troubleshooting that at this point
|
|
0:59:40
|
could be another task, something that we would do for
|
|
0:59:44
|
the yesterday with the or actually really something that
|
|
0:59:48
|
we would do toward the media module because if it´s
|
|
0:59:53
|
sending unicasts and that means it was instructed
|
|
0:59:55
|
to send unicast which is more relating to the CUCM server
|
|
1:00:00
|
part of things. It doesn´t necessarily both really has
|
|
1:00:03
|
nothing to do with the infrastructure itself
|
|
1:00:05
|
whether it´s set up properly not for multicast.
|
|
1:00:08
|
OK? So we have looked at performance monitor, RTMT, command line.
|
|
1:00:16
|
Performance monitor we´ve looked at a number of the command line,
|
|
1:00:19
|
utilities such as the risdb query.
|
|
1:00:23
|
We´ve look at trace files although we had a problem
|
|
1:00:25
|
problem reading and writing from the server.
|
|
1:00:27
|
Database we can probably reboot that pub and get a little better
|
|
1:00:30
|
performance although RTMT did yield some, a better benefits there
|
|
1:00:36
|
and again I have seen those issues with the SSH, in fact
|
|
1:00:40
|
dealt with the number of issues, in fact it´s a
|
|
1:00:43
|
interesting that, who was it down here that brought up?
|
|
1:00:47
|
Revil that brought up, if we have SFTP in the lab.
|
|
1:00:52
|
I´ve actually run into a number of issues with CUCM,
|
|
1:00:56
|
most specifically 7.X releases with the
|
|
1:01:15
|
that with a number of issues regarding
|
|
1:01:19
|
SFTP to and from the CUCM servers and also SSH.
|
|
1:01:26
|
So I believe the issue that we´re facing with the
|
|
1:01:29
|
log files stopping their flow in the middle.
|
|
1:01:33
|
If the actual end of the file hadn´t completed yet was that,
|
|
1:01:37
|
it was an SSH transmission.
|
|
1:01:41
|
It could be on my client end but I doubt it I use it for a lot of other
|
|
1:01:45
|
unix boxes and I don´t have issues with it so
|
|
1:01:47
|
leave it´s probably related to the CUCM.
|
|
1:01:51
|
Well maybe not the best for viewing trace files
|
|
1:01:54
|
certainly good for viewing performance monitor, which isn´t
|
|
1:01:57
|
real time streaming, certainly good for a number of quick
|
|
1:02:03
|
queries whether it´s database replication or
|
|
1:02:08
|
ris database information.
|
|
1:02:13
|
Looking at files, TFTP file management things of that nature
|
|
1:02:17
|
finding up a host names of the server when they´re,
|
|
1:02:20
|
sometimes it´s no other way like the CUP server.
|
|
1:02:28
|
OK, We also look a lot at the bat tool and
|
|
1:02:32
|
various things that it can help us to in the lab
|
|
1:02:35
|
as well as just in regular life.
|
|
1:02:40
|
Hey Mark, in regards to the lab component
|
|
1:02:45
|
actually seen in the lab everything is
|
|
1:02:48
|
started for you in a lot of things are pupils
|
|
1:02:53
|
in regards to that when you get in to lab is the best
|
|
1:02:57
|
practice maybe just to go and then restart all the services yourself
|
|
1:03:00
|
again as well as maybe reset all your
|
|
1:03:04
|
service parameters and your cross parameters back to
|
|
1:03:07
|
default just in case they´ve change anything?
|
|
1:03:11
|
That´s a great question David, yes, I would say absolutely
|
|
1:03:15
|
if you do come in to a lab where there has been a number of
|
|
1:03:20
|
pieces of configuration that have already been
|
|
1:03:22
|
done for you as you mentioned services activated possibly started.
|
|
1:03:28
|
You also mentioned service and I´d add on service parameters.
|
|
1:03:32
|
Those are a perfect perfect in fact the number one
|
|
1:03:36
|
place that whenever I create labs
|
|
1:03:38
|
and create built in and parent troubleshooting within the lab.
|
|
1:03:41
|
It´s the number one place that I go to
|
|
1:03:47
|
help the student along is, there are so many things,
|
|
1:03:52
|
in fact we might just have almost an entire module if we don´t cover
|
|
1:03:57
|
all the various parameters in all the other
|
|
1:04:01
|
various modules that we´ll be doing deep dive sessions on
|
|
1:04:04
|
we don´t cover them all, we might just have an
|
|
1:04:06
|
entire module based on service paramaters because first of all
|
|
1:04:11
|
there´s a number of services, not all of which we´re too concern about
|
|
1:04:15
|
them changing things on, but they could,
|
|
1:04:18
|
but the main one being the call manager service and
|
|
1:04:23
|
especially once we click advance mode, there are just hundreds of fields.
|
|
1:04:28
|
A lot of additional functionality and features,
|
|
1:04:31
|
a lot of things that could intentionally
|
|
1:04:35
|
like I said help us with, in the same way that
|
|
1:04:37
|
Call Cisco bugs features so quote and quote helps us with,
|
|
1:04:42
|
but there´s a lot things they could do, one of the ones that´s.
|
|
1:04:46
|
A favorite of mine is
|
|
1:04:49
|
this one is right here, strip the hash, or octothorpe sign
|
|
1:04:54
|
from the called party number, by default this is true
|
|
1:04:56
|
which means that if you´ve ever created
|
|
1:04:59
|
CTI or rather a translation or a route pattern
|
|
1:05:06
|
and you have a duplicate pattern with a hash at the end.
|
|
1:05:10
|
You don´t necessarily need the discard digit of preDot and
|
|
1:05:16
|
trailing pound or is it?
|
|
1:05:23
|
preDot trailing pound, OK, that´s the best thing to use
|
|
1:05:28
|
because that will definitely get rid of the dot
|
|
1:05:30
|
everything before the dot and that trailing hash
|
|
1:05:34
|
trailing pound, trailing hash, whatever you want to call it.
|
|
1:05:38
|
But it´s done for you automatically, but it´s very
|
|
1:05:42
|
possible they could have set it to false, you can always
|
|
1:05:44
|
see the default or recommended value for the right,
|
|
1:05:48
|
but you don´t have time to search through everything.
|
|
1:05:52
|
So as you mentioned set to default. Are you sure it´s going to replace
|
|
1:05:56
|
all service parameter values including the advance one?
|
|
1:06:00
|
For call manager active service with the default settings
|
|
1:06:03
|
it can´t be undone, are you sure? Yes, you´re sure.
|
|
1:06:07
|
That´s a great idea, definitely seomthing that I always recommend
|
|
1:06:11
|
studens do when they first get in to the CCI voice lab
|
|
1:06:15
|
is reset, at least the primary, I mean you may not
|
|
1:06:18
|
go through every single service taht could take awhile,
|
|
1:06:22
|
plus if you note, this it was on 177.1.10.10
|
|
1:06:29
|
OK? Now, anything that says,
|
|
1:06:36
|
the headings has clusterwide parameter, if you set in on one
|
|
1:06:41
|
or if you set to default on 1, it sets to default on both.
|
|
1:06:44
|
Anything that does not say clusterwide like this is an active parameter
|
|
1:06:49
|
on this server, actually has to be changed on both server
|
|
1:06:53
|
so in other words CDR enabled, if they did not want CDR enabled.
|
|
1:06:58
|
If you default it on 1, it does not necessarily, well does not
|
|
1:07:01
|
default it on the other becasue this is part of the system
|
|
1:07:03
|
under the particular server, so watch for that
|
|
1:07:07
|
and I would´t say that you probably have to go through
|
|
1:07:09
|
every single one, but certainly through call manager
|
|
1:07:12
|
certainly the enterprise parameters,
|
|
1:07:14
|
and then if you run in to any issues on all the others,
|
|
1:07:17
|
any of the others I should say. You know maybe
|
|
1:07:20
|
the media isn´t working properly then.
|
|
1:07:24
|
You might want to go and set the default over here
|
|
1:07:26
|
or other various places as well, also along with that
|
|
1:07:31
|
is a good idea to always,
|
|
1:07:36
|
restart or actually do factory default
|
|
1:07:40
|
restore factory default, is the command that I´m looking for
|
|
1:07:44
|
on the CUE, the unite express queue module
|
|
1:07:48
|
because just like, so far everyone that I´ve talked to that writes tk
|
|
1:07:56
|
tcl or expect scripts to interact with devices and
|
|
1:08:02
|
hit them to clear off their configs or do whatever they want
|
|
1:08:07
|
No one that I´ve talked to has had much luck with the CUE device
|
|
1:08:10
|
because it´s variable reboot time is almost impossible to predict
|
|
1:08:14
|
and the one thing you don´t ever want a expect script
|
|
1:08:17
|
to do is just sit there and wait infinitely,
|
|
1:08:21
|
you know because then you´ll never complete it,
|
|
1:08:23
|
you will never know the status so it´s very likely
|
|
1:08:28
|
that your CUE module could possibly have existing configuration on it
|
|
1:08:33
|
and not even just from a proctor trying to help you quote and quote
|
|
1:08:38
|
in inherent trouble, but even from a previous candidate
|
|
1:08:42
|
and some candidates going in to a lab might
|
|
1:08:45
|
be tempted to think, oh well that could
|
|
1:08:47
|
really save some time if someone´s already configured it for me
|
|
1:08:50
|
yes, but you don´t the status of the candidate that went before
|
|
1:08:53
|
for you and you´d rather be in control of that so that´s one
|
|
1:08:56
|
other thing that I definitely default when I get to the lab.
|
|
1:09:00
|
Good question.
|
|
1:09:03
|
The others
|
|
1:09:08
|
How many times, in your opinion is a bit to tackle or
|
|
1:09:14
|
I mean is that can I take Brussels or maybe sent bit by bit because
|
|
1:09:19
|
experiencing some lag on accessing docs and virtual Brussels lab
|
|
1:09:24
|
so they commented or you know had a look at any delay
|
|
1:09:33
|
accessing the equipment?
|
|
1:09:38
|
Well, I haven´t heard too many issues, I´ve heard
|
|
1:09:41
|
one or two from Brussels, but not too many to make me concern
|
|
1:09:45
|
from RTP I haven´t heard of any issues.
|
|
1:09:48
|
I would actually probably recommend either Brussels or RTP
|
|
1:09:53
|
and the reason those two over San Jose
|
|
1:09:56
|
eventhough the hardware is local to San Jose is that
|
|
1:09:59
|
their, I don´t believe there´s a full-time
|
|
1:10:03
|
Well let me actually back up and approach the question in this way.
|
|
1:10:07
|
For every time that you go sit down
|
|
1:10:10
|
and take a CCI lab at any Cisco location .
|
|
1:10:14
|
There is typically one and sometimes two proctors
|
|
1:10:19
|
proctoring the entire room of candidates
|
|
1:10:22
|
and not just for one track, they´re proctoring the route switch
|
|
1:10:26
|
security, the service provider and then for the locations that
|
|
1:10:30
|
offer voice, the voice tracks as well because route switch security
|
|
1:10:35
|
service provider offered almost everywhere.
|
|
1:10:37
|
Some of the other ones, SP ops, wireless
|
|
1:10:41
|
storage those are only offered in very limited places
|
|
1:10:44
|
and sometimes even on limited days,
|
|
1:10:46
|
but at the very least the proctor is almost always proctoring for
|
|
1:10:51
|
3 if not 4 different tracks.
|
|
1:10:53
|
Now that doesn´t mean that the proctor
|
|
1:10:55
|
is certified in all of those tracks, they are definitely a CCIE.
|
|
1:11:01
|
Many of them or dual or triple or you know whatever CCIEs but,
|
|
1:11:05
|
they are not necessarily, let´s say actually most are single or dual
|
|
1:11:11
|
and they´re not necessarily CCIEs in the track that you´re taking.
|
|
1:11:15
|
So, for instance almost all the proctors have historically been
|
|
1:11:20
|
and at least route switch and possibly something else or maybe securing else.
|
|
1:11:26
|
And at San Jose that´s still the case, now
|
|
1:11:29
|
there were, you know for awhile there was
|
|
1:11:34
|
Ben Ing who is the CCI voice content manager
|
|
1:11:38
|
was also a proctor, kind of in a dual role
|
|
1:11:42
|
there in San Jose, he stationed permanently there in San Jose.
|
|
1:11:46
|
While he is still, his cubicle is still in the actual CCI voice
|
|
1:11:50
|
tetsing room in San Jose, he is no longer proctor, actually
|
|
1:11:56
|
proctoring over exams. He´s not really available for questions
|
|
1:12:01
|
and he´ll tell you that, guide you over to one of the other
|
|
1:12:05
|
well informed, let´s call them instructors, the proctors, but they
|
|
1:12:13
|
might very well not necessarily have their CCI voice.
|
|
1:12:18
|
His counter part, the other one that helps set up the voice program
|
|
1:12:22
|
is located in Brussels.
|
|
1:12:24
|
and he is still the proctor there, so you can certainly get
|
|
1:12:28
|
you know immediate answers from the proctor in Brussels
|
|
1:12:34
|
and the primary proctor in RTP, Kelly, who just took over.
|
|
1:12:38
|
She´s actually a single CCI in voice, so
|
|
1:12:41
|
while most locations it´s the voice people that are
|
|
1:12:44
|
kind of a little bit of a disadvantage because
|
|
1:12:47
|
the other proctors have to kind of get up to speed.
|
|
1:12:50
|
So to speak on the tasks that are
|
|
1:12:53
|
written down in those labs and they´re supposed
|
|
1:12:55
|
to be able to answer questions about them
|
|
1:12:57
|
they may not have an intimate knowledge of the protocols
|
|
1:13:00
|
and everything so they maybe able to answer
|
|
1:13:03
|
just the most, you know strict sense of
|
|
1:13:09
|
the wording of the task and that´s about it
|
|
1:13:12
|
and they might not really have a full underastanding of the lab
|
|
1:13:16
|
and they don´t need to in some senses
|
|
1:13:19
|
in order to be able to answer questions about wording and
|
|
1:13:23
|
becasue they have a specific you know regimen of
|
|
1:13:27
|
pick up this pohone, dial this number
|
|
1:13:30
|
Here is exactly what you should hear or see,
|
|
1:13:32
|
if it doesn´t happen then you know
|
|
1:13:35
|
don´t get the points, candidate doesn´t get the points
|
|
1:13:37
|
if it does happen, the candidate does get the points
|
|
1:13:40
|
and wow that´s all well and good.
|
|
1:13:42
|
Obviously you and I know that if you have an intimate knowledge
|
|
1:13:47
|
and are certified in the track that you´re trying to either grade or.
|
|
1:13:51
|
Most importantly when the students are sitting there,
|
|
1:13:53
|
ask questions about and answer questions about you´re going to be able to
|
|
1:13:58
|
help the student or candidate a lot better.
|
|
1:14:02
|
If they show themselves to have an expert level
|
|
1:14:06
|
understanding of the protocols and everything and they´re just
|
|
1:14:09
|
asking for clarification or maybe they´re not undertanding something properly
|
|
1:14:13
|
the people, the proctors that have that intimate knowledge of the
|
|
1:14:18
|
of the protocols and the test being administered.
|
|
1:14:20
|
We are going to be able to help the candidate a lot
|
|
1:14:23
|
all that´s to say if you come up and just say
|
|
1:14:25
|
hey I don´t what this question means, can you help me?
|
|
1:14:27
|
No proctor, whether there are a voice or a
|
|
1:14:29
|
route switch or whatever is going to help you,
|
|
1:14:31
|
but they´re not there to take the test for you.
|
|
1:14:34
|
They are there to clarify things and if you show that you have
|
|
1:14:36
|
good knowledge of what it is, you're just missing something, maybe wording or
|
|
1:14:41
|
lost in translation, or grammar or something like that
|
|
1:14:44
|
they´re going to be very quick to help you.
|
|
1:14:48
|
Also to answer Christopher´s question as
|
|
1:14:51
|
to being interested how the equipments set up in the lab
|
|
1:14:55
|
in terms of physical equipment, you will have
|
|
1:14:58
|
2 phones at every site in front of you.
|
|
1:15:01
|
So you´ll have at least 6 phones, possibly 7 or 8, but at least 6.
|
|
1:15:06
|
And then you´ll also have a PSTN phone and they are all 7965s.
|
|
1:15:15
|
It really doesn´t matter whether you study with 61s
|
|
1:15:20
|
Joe can you hear me now? OK.
|
|
1:15:24
|
OK.
|
|
1:15:26
|
I really doesn´t matter if you´re practicing with 61s or 62s
|
|
1:15:30
|
there´s one, well actually there´s 2 things
|
|
1:15:33
|
that we care about that the 62s do that are a little bit better than 61s,
|
|
1:15:37
|
which is that they can negotiate the ILBC code act
|
|
1:15:42
|
and that they have which actually we don´t really
|
|
1:15:44
|
care about this other one, they have the enhanced
|
|
1:15:49
|
handset for g711 wide band.
|
|
1:15:55
|
Both 61s and 62s have the speaker phone that has the
|
|
1:15:59
|
g722 enabled codec for the speaker phone,
|
|
1:16:03
|
but the handsets are enhancing the 62s
|
|
1:16:06
|
you can buy an upgrade for the 61s, but really to the labs
|
|
1:16:10
|
perspective ILBC negotiation is the only thing that a 62 can do
|
|
1:16:14
|
that a 61 cannot do. So for the money,
|
|
1:16:19
|
you´re probably best studying as 61, wihout being said
|
|
1:16:22
|
the real lab does test with 65s.
|
|
1:16:26
|
Probably just because they look and they have a lot of
|
|
1:16:29
|
easy inventory to get access to because it was not
|
|
1:16:31
|
as many people bought them as did by 61 and 62s.
|
|
1:16:35
|
You have 19 inch, flat panel LCD monitor, new laser mouse
|
|
1:16:42
|
with scroll at least this is the way it is in RTP and San Jose.
|
|
1:16:46
|
Very fast computer, someone mentioned I think it was David
|
|
1:16:51
|
about the lagging to the documentation.
|
|
1:16:55
|
It is the actual website, the cisco.com website
|
|
1:16:59
|
you are going to, you´re not going to an offline cache version
|
|
1:17:02
|
or dvd like they used to do. I took my first route switch lab in 2002.
|
|
1:17:09
|
I actually had a two-time cd ROM
|
|
1:17:12
|
and the whole tower shook when the whole documentation
|
|
1:17:15
|
CD started to spin up, that was, things have gotten a lot better since then
|
|
1:17:20
|
but anyway, there should not be any lag to the documentation
|
|
1:17:27
|
You know the only lag would be maybe if you are
|
|
1:17:29
|
international and you´re trying to download pdf´s
|
|
1:17:33
|
but 17 make pdfs, but otherwise shouldn´t have a problem
|
|
1:17:38
|
Christoper asks, is there any plenty of desk space to take notes
|
|
1:17:41
|
and room to spread out or you cramp in to a small cubicle?
|
|
1:17:44
|
It is a cubicle, but you are given amples
|
|
1:17:48
|
space to spread out for your your three ring binder which is your one side.
|
|
1:17:54
|
You´re computer, monitor and keyboard in the middle,
|
|
1:17:56
|
and your notes on the other side, and all of your phones are
|
|
1:17:59
|
hung up in the desk surrounding you in the cubicle so
|
|
1:18:03
|
there´s actually ample plenty of space to be comfortable.
|
|
1:18:10
|
I mean you can´t really spread out much beyond that
|
|
1:18:12
|
that I don´t know that you really need to or have any other
|
|
1:18:14
|
materials that you can take in or help you out with.
|
|
1:18:20
|
One thing to keep in mind is that you are not allowed
|
|
1:18:23
|
to bring in anything like watches or pens
|
|
1:18:27
|
P-E-N-S, pens, they will provide pens and pencils.
|
|
1:18:32
|
Typically pencils, but there´s been too many people that has been noted
|
|
1:18:39
|
were caught having usb watches or usb pens or
|
|
1:18:44
|
anything electronic or something that could look like,
|
|
1:18:46
|
it could be electronic, you won´t be allowed to bring them.
|
|
1:18:49
|
|
