Rebooting Software to Modify Configuration Parameters
Sometimes you might need to change your configuration settings in the XECfgParm.dat file while the
system is in-service. To change a configuration while the system is in-service, perform the following
procedure:
Caution Performing this procedure stops the functioning of the Cisco PGW 2200 Softswitch software. Perform
this step only while in contact with Cisco Technical Assistance Center (TAC) personnel. See the
“Obtaining Documentation and Submitting a Service Request” section on page xviii for information on
contacting the Cisco TAC.
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 standby Cisco PGW 2200 Softswitch and change directories to the /etc subdirectory by
entering the
cd /opt/CiscoMGC/etc UNIX command.
Step 3 Open the XECfgParm.dat by using a text editor, such as vi.
Step 4 Search for the parameters that are specified in the referring procedure and verify that they are set to the
correct values. If they are set correctly, proceed to Step 11. Otherwise, proceed to Step 5 to begin the
process of correcting your configuration.
Step 5 Modify the incorrect parameters that were identified in Step 4 to match the correct values.
Step 6 Save your changes and close the text editor.
Step 7 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 8 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.
Step 9 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 transmitted 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 Repeat Step 2 through Step 9 for the newly standby Cisco PGW 2200 Softswitch.
If repeating Step 2 through Step 9 resolves the problem, the procedure is complete. Otherwise, proceed
to Step 10.
Step 11 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.
