Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving SS7 Network Related Problems
Verifying Proper Loading of a Dial Plan
Step 1 If you have not already collected system data, refer to 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 the dial plan was loaded incorrectly.
If the dial plan was not loaded correctly, reload the dial plan by saving and activate your dial plan again
as described in the “Saving and Activating your Provisioning Changes” section on page 3-65.
If there are no logs that indicate that the dial plan was loaded incorrectly, 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.
Verifying Configuration to Support Multiple Versions of SS7
Step 1 If you have not already collected system data, refer to the method that is described in the “Collecting
System Data for Cisco TAC” section on page 6-93.
Step 2 Log in to the active Cisco PGW 2200 Softswitch and change directories to the /etc subdirectory by
entering the
cd /opt/CiscoMGC/etc UNIX command.
Step 3 Open the alarmCats.dat using a text editor, such as vi.
Step 4 The third column in the file indicates the severity level for each alarm. Verify that the severity level for
the All C7 IP Links Fail alarm is set to 2. If the severity level is set correctly, the procedure is complete.
Otherwise, proceed to Step 5 to begin the process of correcting your configuration.
Step 5 Set the severity level of the All C7 IP Links Fail alarm to 2.
Step 6 Save your changes and close the text editor.
Step 7 Repeat Step 2 through Step 6 on the standby Cisco PGW 2200 Softswitch.
Step 8 Stop the Cisco PGW 2200 Softswitch software on your 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 your standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
Step 10 Perform a manual switchover from the active Cisco PGW 2200 Softswitch, 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.
