Daily Tasks
Note If you enter the rtrv-dest:all MML command after a switchover has occurred, the state of some
of the signaling services might be listed as undefined (UND). UND is the default state for a
signaling service when the system starts. In this instance, UND indicates that the Cisco PGW
2200 Softswitch has not received a service state message for the associated signaling service
since the switchover occurred. No user action is required.
Step 2 If the primary service state is not in service (IS) for any of the signaling service, check your alarms
retrieval MML session for signaling-related alarms. The “Monitoring the Alarms Status” section on
page 3-7 describe the method for setting up an alarms-retrieval MML session.
If a signaling-related alarm appears, you can determine the appropriate course of action by searching for
the corrective actions for that alarm in the “Alarm Troubleshooting Procedures” section on page 6-4. If
the alarm is not in that section, corrective action is not required. More information on the alarm can be
found in Cisco PGW 2200 Softswitch Release 9 Messages Reference.
You can also find additional information on the conditions that caused the alarms by viewing the system
logs. The logs can be viewed using the log viewer, part of the Cisco MGC viewer toolkit. For information
on using the log viewer, see the “Using the Log Viewer” section on page 3-128.
Note You can also use the rtrv-dest MML command to retrieve information on individual signaling services
using the procedure that is presented in the “Retrieving Signaling Service States” section on page 3-45.
Understanding the Signaling Service State Information
The following sections describe the information that is returned by the system when you enter the
rtrv-dest command, as shown in the following example:
"sigsrv1:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"
"sigsrv2:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"
"sigsrv3:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"
Destination
The first field lists the MML name of the associated signaling service. In the preceding example, the
signaling services are sigsrv1, sigsrv2, and sigsrv3.
Package
The PKG field lists the protocol package that is associated with the destination. In the example, the
protocol is SS7-ANSI.
Association
The ASSOC field shows the type of association, either unknown, switched, or a specific channel for the
signaling service. In the example, the association type is SWITCHED.
