REMOTE ACL CONFIG with CISCO Switches or Routers:

If your facility is not in your office or you are accessing a Cisco router or switch remotely then i suggest a few things, from first hand experience :(.

Accessing the ACL on your Cisco Router: first thing to do is have the new version of the ACL in notepad or textedit review it and make sure the changes you are about to apply are correct. Then ssh or telnet to your box use the reload in XX (min), i use reload in 5. That way i can go do the following:

(Access the router/switch)

Router#show run
(Just check the config)

Router#reload in 5
Router#config t
Router(config)#int gX/X
Router(config-if)#no ip access-group XXX in
Router(config-if)#exit
Router(config)#no access-list XXX
(copy the ACL in notepad and past it to the session)
Router(config)#ctrl+V (pasting the new ACL to the router)
Router(config)#exit
Router#show run
(make sure the ACL is what you want)
Router#config t
Router(config)#int GX/X
Router(config-if)#ip access-group XXX in
Router(config-if)#exit
Router(config)#exit
Router#reload cancel
Router#wr

and you are done…

CANTATA IMG-1010 Call Tracing:

Config IMG-1010 to display active calls and “gerp” cause code’s for each calls to display in terminal:

The IMG-1010 has a very nice feature to let you watch the realtime call flow between IP (SIP or H.323) and SS7. This is great because otherwise we would need to interupt service with a protocal analyser.

This is how it works.

To enable this feature we could just do a telnet session from any linux box that has IP access to the IMG-1010. In our case the GCEMS controller is in Miami, NAP of the Americas, and our IMG-1010 are in Telecom’ arount the world.

Telnet to your IMG-1010:
telnet 255.255.255.255|tee capturetext.txt

username:username
password:password

You should have the username and password to your IMG-1010.

Enter these comands in order to enable call tracing via the CLI.

>W
GEL>29
CALL>P
–logging & Printing All Events–
CALL>_

now open a new terminal window.

[excalsw@hostname]$ tail capturetext.txt |grep “cause”

Where capturetxt.txt is the filename used in the telnet “|tee” command.

Resize your terminal window so you see complete lines of text.Your output should look like this

01:56:13.496 CALL(SS7) (00:8782:01) SENT REL (0×1938:0×3338:449) cause 16

Where cause 16 is the SS7 Cause code of the call.
Where 00:8782:01 is the call ID - so if you would like to look at the complete call. just use this command:

grep “00:8782″ syspogtext.txt and you should see the complete call flow.

This output will look something thik this:

I have jus displayed part of a call…

To stop call tracing:
CALL>r
CALL>q
GEL>q
>

I find these tools very helpfull when diagnosing issues…

The Call Tracing is a feature that you can also enable in you “Client View Application” on the GCEMS Server.

Just go to the /opt/cantata/common/calltracing directory and check for the name of the file to perform operations. Of course you could export the file to a qsl database and view the info via a web page.
