Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Step 4 Verify that the IP path between the media gateway and the authentication server is working properly. If
you find no problems in the IP path between the media gateway and the authentication, proceed to
Step 5. Otherwise, fix the identified IP path problems.
Step 5 Verify that the authentication server is working properly. If you find no problems in the authentication
server, proceed to Step 6. Otherwise, fix the identified problems in the authentication server.
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.
Virtual_IP_Addr Mismatch
This alarm occurs when the virtual IP addresses configured in XECfgParm.dat files on the active and the
standby Cisco PGW 2200 Softswitch do not match.
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 the value that is set for the XECfgParm.dat parameter, *.Virtual_IP_Addr, on the active Cisco
PGW 2200 Softswitch.
Step 3 Verify the value that is set for the XECfgParm.dat parameter, *.Virtual_IP_Addr, on the standby Cisco
PGW 2200 Softswitch.
If the parameter values match, proceed to Step 10. Otherwise, proceed to Step 4.
Step 4 Log in to the standby Cisco PGW 2200 Softswitch and change directories to the /etc subdirectory by
entering the cd /opt/CiscoMGC/etc UNIX command:
Step 5 Open the XECfgParm.dat file by using a text editor, such as vi.
Step 6 Set the value of the *.Virtual_IP_Addr parameter to match the value on the active Cisco PGW 2200
Softswitch.
Step 7 Save the changes and close the text editor.
Step 8 Stop 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 9 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.
If that resolves the problem, the procedure is complete. Otherwise, proceed to Step 10.
Step 10 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.
