Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
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 IP addresses of the local interfaces on the standby Cisco PGW 2200 Softswitch by using the
ifconfig -a UNIX command.
The system returns a response indicating the IP addresses of your local interfaces.
Step 3 Verify that the IP addresses obtained in Step 2 match the values that are set for the IP_Addr1 through
IP_Addr4 parameters in the XECfgParm.dat file.
If the settings for the local IP addresses are not the same, proceed to Step 4.
If the settings for the local IP addresses are the same, proceed to Step 12.
Step 4 Log in to your active Cisco PGW 2200 Softswitch and change directories to the /opt/CiscoMGC/etc
directory using the cd /opt/CiscoMGC/etc UNIX command:
Step 5 Open the XECfgParm.dat file in a text editor, such as vi.
Step 6 Search for the IP_Addr properties and change the properties that are not configured correctly.
Step 7 Save the file and exit the text editor.
Step 8 Shut down the Cisco PGW 2200 Softswitch software on the standby Cisco PGW 2200 Softswitch by
entering the /etc/init.d/CiscoMGC stop UNIX command:
Note Shutting down the Cisco PGW 2200 Softswitch software on the active Cisco PGW 2200
Softswitch causes the currently standby Cisco PGW 2200 Softswitch to become the active Cisco
PGW 2200 Softswitch.
Step 9 Restart the Cisco PGW 2200 Softswitch software on this Cisco PGW 2200 Softswitch by entering the
/etc/init.d/CiscoMGC start command:
Step 10 When the Cisco PGW 2200 Softswitch software is fully activated, log in to the active
Cisco PGW 2200 Softswitch and perform a manual switchover, using the sw-over::confirm MML
command:
Step 11 Repeat Step 2 through Step 9 on the newly standby Cisco PGW 2200 Softswitch.
If the problem has not been resolved after you have completed those steps, proceed to Step 12.
Step 12 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.
