Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving SS7 Network Related Problems
Step 5 Shut down the Cisco PGW 2200 Softswitch software on your active Cisco PGW 2200 Softswitch, using
the procedure in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on
page 2-4.
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 6 Restart the Cisco PGW 2200 Softswitch software on the Cisco PGW 2200 Softswitch, using the
procedure in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
Step 7 After 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 procedure 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.
Step 8 After the manual switchover is complete, log in to the newly active Cisco PGW 2200 Softswitch, start
an MML session and enter the
prov-sync command to synchronize the Cisco PGW 2200 Softswitches.
Step 9 After the synchronization is complete, perform a manual switchover using the procedure 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.
Step 10 After the manual switchover is complete, log in to your newly standby Cisco PGW 2200 Softswitch and
change directories to the /opt/CiscoMGC/etc directory using the
cd /opt/CiscoMGC/etc UNIX
command.
Step 11 Open the XECfgParm.dat file in a text editor, such as vi.
Step 12 Search for the pom.dataSync property and ensure that it is set to true.
Step 13 Save the file and exit the text editor.
Step 14 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:
Step 15 Restart the Cisco PGW 2200 Softswitch software on the Cisco PGW 2200 Softswitch by entering the
/etc/init.d/CiscoMGC start command.
