Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Tracing
• Use the following command to start a 12 hour call trace of the call with duration longer than 3 hours
in the trunk group tg-6006:
sta-sc-trc:tg-6006,duration=10800,prd=43200,confirm
Note You can use the following two commands to perform call traces on a standby Cisco PGW 2200
Softswitch.
sta-sc-trc:<sig_path>:[span=x[,rng=y][,tc=z[,rng=w]]][,mcl=m][,prd=n][,log=”log”],
confirm
sta-sc-trc:<trunkgroup>:[trk=x[,rng=y]][,mcl=m][,prd=n][,log=”log”],confirm
Step 2 Make the call.
Stopping A Call Trace
You can stop a call trace session by issuing the stp-sc-trc MML command. To stop a call trace session
on a particular signaling service, log in to the active Cisco PGW 2200 Softswitch, start an MML session,
and enter the
stp-sc-trc: sig_srv | trkgrp command.
Where:
• sig_srv—MML name for the signaling service on which you are running a call trace.
• trkgrp—MML name for the trunk group on which you are running a call trace.
For example, to stop a call trace session on a trunk group that is called T-1-1, enter the
stp-sc-trc:T-1-1
command.
To stop all call trace sessions, log in to the active Cisco PGW 2200 Softswitch, start an MML session,
and enter the
stp-sc-trc:all command.
The system returns a response like the following:
Media Gateway Controller 2000-03-21 15:28:03
M COMPLD
"ALL:Trace stopped for the following files:
../var/trace/_dpc1_20000321152752.btr
"
Retrieving Names of Open Call Trace Files
To retrieve the names of call trace files for sessions that are in progress, log in to the active Cisco PGW
2200 Softswitch, start an MML session, and enter the
rtrv-sc-trc command.
The system returns a response like the following:
Media Gateway Controller 2000-03-21 15:28:03
M RTRV
"RTRV-SC-TRC:Trace in progress for the following files:
../var/trace/_dpc1_19991221131108.btr
../var/trace/sigtest_dpc2_19991221131109.btr
"
Starting with Cisco PGW 2200 Softswitch Release 9.7(3) Patch 8, you can use the
rtrv-sc-trc::stopreason command to retrieve the stop reason of the last trace file.
