Tracing

Step 2 To change directories, enter the cd /opt/CiscoMGC/var/trace UNIX command.

Step 3 Use a text file viewer, such as vi, to view the contents of the log file.

Stopping an Abnormal Call Termination Trace

You can stop an in-progress abnormal call termination trace by issuing the stp-abn-trc MML command.

To stop the trace in progress, log in to the active Cisco PGW 2200 Softswitch, start an MML session,

and enter the

stp-abn-trc:

sig_srv

command.

Where:

sig_srv is the MML name for a signaling service on which the abnormal call termination trace is run.

For example, to stop an abnormal call termination trace that is run on a signaling service, which is called

ss7srv1, enter the

stp-abn-trc:ss7srv1 command.

The system responds with a response like the following:

Media Gateway Controller 2000-05-26 07:02:11

M COMPLD

"Trace stopped for the following file:

../var/trace/_20000526070211.abn

To stop all in-progress abnormal call termination traces, log in to the active Cisco PGW 2200 Softswitch,

start an MML session, and enter the

stp-abn-trc:all command.

The system returns a response like the following:

Media Gateway Controller 2000-05-26 07:02:11

M COMPLD

"ALL:Trace stopped for the following files:

../var/trace/_20000526070211.abn

Performing a TCAP Trace

To run a TCAP trace on your system, perform the following steps:

Step 1 Start the TCAP trace by logging in to the active Cisco PGW 2200 Softswitch, starting an MML session,

and entering the

sta-tcap-trc command.

The system begins sending TCAP trace messages to the active system logs file.

Step 2 View the active system logs file according to instructions in the “Viewing System Logs” section on

page 6-90. Note any TCAP trace messages, such as hex dumps of messages that are sent to the SCCP

layer.

Step 3 When the TCAP trace is complete, enter the stp-tcap-trc command to stop the TCAP trace.
