Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
LIF FAIL
This alarm occurs when a local Ethernet interface fails.
Corrective Action
To correct the problem, perform the following steps:
Note If the Association Degraded or Association Failed alarms occur along with this alarm, follow the
procedure that is defined in the “Resolving an Association Alarm” section on page 6-122.
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 Use the Log viewer in the MGC Viewer toolkit to search the system log file from the same time period
as this alarm for a GEN_ERR_IPINTF_FAIL log message.
Note For more information on using the Log viewer, see
Cisco PGW 2200 Softswitch Release 9 Operations, Maintenance, and Troubleshooting Guide.
If you detect a GEN_ERR_IPINTF_FAIL log message, proceed to Step 3. Otherwise, proceed to Step 7.
Step 3 Identify the cause of the failure from the information in the log message.
If the cause in the log message is “Admin Down,” the interface was taken down using an administrative
command. Proceed to Step 4.
If the cause in the log message is “Link Down,” the Ethernet path failed. Proceed to Step 5.
Step 4 Enter the ifconfig interface up UNIX command to restore the link to service:
Where:
interface—IP address of the affected interface.
If the interface is restored and is working fine, the procedure is complete. Otherwise, proceed to Step 7.
Step 5 Verify that the cable connected between the interface and the associated Ethernet switch is working
properly.
If the cable is working correctly, proceed to Step 6.
If the cable is not working correctly, replace it. If replacing the cable resolves the problem, the procedure
is complete. Otherwise, proceed to Step 6.
Step 6 Verify that the associated Ethernet switch is working properly.
If the Ethernet switch is working correctly, proceed to Step 7.
If the Ethernet switch is not working correctly, troubleshoot the problem as indicated in the
documentation for your switch. If that resolves the problem, the procedure is complete. Otherwise,
proceed to Step 7.
Step 7 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.
