Cisco ITP-L Error Messages
If you need to contact your technical support representative for assistance, be prepared to provide the
Cisco ITP-L and Cisco PGW 2200 Softswitch debug trace information. You should capture this
information while the problem was occurring. In most cases, the backhaul trace and the LSC trace from
the Cisco ITP-L are required. If the problem is associated with link alignment, you should also include
the IAC trace output. Trace information can help the investigator identify the problem on the Cisco
ITP-L or on the Cisco PGW 2200 Softswitch.
To enable MTP2 traces, enter the following commands:
debug ss7 mtp2 back channel
debug ss7 mtp2 lsc channel
debug ss7 mtp2 iac channel
To turn off debug trace, enter the un all command.
The output from a show version command provides explicit details about the image and branch
information. This information specifically identifies which branch of code to investigate.
The output from a show run command indicates which Cisco ITP-L configuration is present. Knowing
the configuration is important because improper configurations can cause many problems, such as timer
durations.
Provide any information from show commands that you used to identify the problem; for example:
show ss7 sm stats
Include any other information that might be useful for understanding or reproducing the problem. This
information helps your technical support representative verify a fix.
