Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
FAIL REMOTE STANDBY
This alarm occurs on the active Cisco PGW 2200 Softswitch when a synchronization operation between
the active and standby Cisco PGW 2200 Softswitches fails. The system automatically clears this alarm
if a synchronization operation succeeds after the failure. If the synchronization succeeds, the system
triggers the Standby Warm Start alarm. See the “Standby Warm Start” section on page 6-75 for more
information.
Corrective Action
To correct the problem, perform the following steps:
Step 1 To collect system data, see the method that is described in the “Collecting System Data for Cisco TAC”
section on page 6-93.
Step 2 Verify that the standby Cisco PGW 2200 Softswitch is in the standby platform state. Use the procedure
that is defined in the “Verifying the Platform State of the Cisco PGW 2200 Softswitches” section on
page 3-2.
If the standby Cisco PGW 2200 Softswitch is in the standby platform state, proceed to Step 3. Otherwise,
proceed to Step 4.
Step 3 Synchronize the standby Cisco PGW 2200 Softswitch with the active Cisco PGW 2200 Softswitch by
entering the prov-sync MML command.
Step 4 Shut down the Cisco PGW 2200 Softswitch software on your standby Cisco PGW 2200 Softswitch, as
described in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on
page 2-4.
Step 5 Restart the Cisco PGW 2200 Softswitch software on your standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
If that resolves the problem, the procedure is complete. Otherwise, proceed to Step 6.
Step 6 Contact the Cisco TAC to analyze the problem further and to determine a solution. For more information
about contacting the Cisco TAC, see the “Obtaining Documentation and Submitting a Service Request”
section on page xviii.
FORCE NODE RESTART
This alarm occurs on the standby Cisco PGW 2200 Softswitch when a new SS7 IOCC is added to the
configuration of the system. This alarm causes the Cisco PGW 2200 Softswitch software on the standby
Cisco PGW 2200 Softswitch to be rebooted. This alarm does not affect the active Cisco PGW 2200
Softswitch.
Corrective Action
To correct the problem, perform the following steps:
Step 1 When the Cisco PGW 2200 Softswitch software has restarted on the standby Cisco PGW 2200
Softswitch, collect system data. Refer to the method that is described in the “Collecting System Data for
Cisco TAC” section on page 6-93.
