Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Step 5 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.
PC UNAVAIL
This alarm occurs when a destination point code (DPC) is unavailable. This alarm can occur if a network
failure isolates the DPC; or, the alarm can occur if a local equipment failure causes a loss of connectivity.
Also, the Cisco PGW 2200 Softswitch can raise the alarm if the DPC, or routes to the DPC, were
configured improperly.
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 The Cisco PGW 2200 Softswitch should also display other alarms that indicate problems with hardware,
the SS7 links, or the network. Resolve those alarms first.
If resolving those alarms does not clear this alarm, proceed to Step 3.
Step 3 Ensure that the provisioning settings for the DPC and for all routes to the DPC and adjacent STPs match
the settings that are used on the far-end, as described in the “Retrieving Provisioning Data” section on
page 3-69.
If the configuration data associated with the DPC is incorrect, begin a dynamic reconfiguration session,
as described in the “Invoking Dynamic Reconfiguration” section on page 3-66.
If the configuration data associated with the DPC is correct, then proceed to Step 4.
Step 4 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.
Peer IP Links Failure
This alarm occurs when the IP links to the peer Cisco PGW 2200 Softswitch are removed or down.
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 Ethernet interfaces for the active and standby Cisco PGW 2200 Softswitches are working
properly.
