Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Step 2 Verify that the standby Cisco PGW 2200 Softswitch is in the standby platform state, using 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, the procedure is complete.
Otherwise, proceed to Step 3.
Step 3 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.
Gen Fail
This alarm occurs when a failure occurs because of resource exhaustion or configuration problems, such
as the following:
• Memory exhaustion
• Queue overflow
• Message congestion
• IPC file cannot be opened
• Expired timer
Log messages in the active system log file indicate the nature of the failure. For the majority of the
failures, this alarm is informational and no user action is required. If the system generates this alarm
because it cannot open an IPC file, you must take corrective action.
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 Search the active system log file, as described in the “Viewing System Logs” section on page 6-90, for
logs that indicate that an IPC file cannot be opened.
If there are no logs that indicate that an IPC file cannot be opened, no further action is required.
If there are logs that indicate that an IPC file cannot be opened, proceed to Step 3.
Step 3 Shut down the Cisco PGW 2200 Softswitch software on the standby Cisco PGW 2200 Softswitch, as
described in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on
page 2-4.
Step 4 Restart the Cisco PGW 2200 Softswitch software on the standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
Step 5 Perform a manual switchover, as described in the “Performing a Manual Switchover” section on
page 3-96.
Caution Switchover operations cause the loss of all SS7 messages that are sent to the Cisco PGW 2200 Softswitch
for approximately three seconds. The switchover affects unstable in-progress calls as well as new calls.
Stable in-progress calls are not affected.
