Platform Troubleshooting
NTP is Used and the Cisco PGW 2200 Softswitch is the Source of the CDRs
If the Cisco PGW 2200 Softswitch is the source of CDRs and NTP maintains system time, the system
time can get out of synchronization with the NTP server only if a user with root access (which should
be strictly controlled) modifies the time on an Cisco PGW 2200 Softswitch. You cannot modify the time
on the NTP server. To correct the system time when an NTP server maintains system time, and the Cisco
PGW 2200 Softswitch is the source of your CDRs, perform the following steps:
Caution This procedure affects service. Perform the procedure during a maintenance period.
Step 1 Stop the Cisco PGW 2200 Softswitch software on both Cisco PGW 2200 Softswitches, as described in
the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on page 2-4.
Step 2 Reboot the Cisco PGW 2200 Softswitches, according to the Sun Microsystems documentation that came
with the system. Rebooting the Cisco PGW 2200 Softswitches restarts the Xntp demon, which
synchronizes the system time with the time on the NTP server.
Step 3 Restart the Cisco PGW 2200 Softswitch software on both Cisco PGW 2200 Softswitches, as described
in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
Securing Your Network
The Cisco PGW 2200 Softswitch introduces a security enhancement for your network. To enable this
enhancement, you must completely install the CSCOh020 security package on your network (which can
consist of Cisco PGW 2200 Softswitch, BAMS, and HSI). For the procedure for installing this security
package, see Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide.
The following sections describe the process for securing your network:
• Securing the Cisco PGW 2200 Softswitch, page 6-187
• Securing Cisco BAMS, page 6-189
Securing the Cisco PGW 2200 Softswitch
Perform the following steps to secure the Cisco PGW 2200 Softswitch:
Step 1 Before you begin the process to secure the network, you must identify the last CDR that the Cisco BAMS
obtained from the Cisco PGW 2200 Softswitch.
Log in to the active Cisco PGW 2200 Softswitch as root and enter the
# cd /opt/CiscoMGC/var/spool
UNIX command to change directories.
Step 2 Enter the # ls -l cdr_yyyymmdd UNIX command to verify the CDR.
