Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Corrective Action
To correct the problem, run a manual COT test, as described in the “Running a Manual Continuity Test”
section on page 6-149.
License server unreachable
This alarm appears if the license server is unavailable. The Cisco PGW 2200 Softswitch looks at the local
license files to retrieve the configuration time TDM ports/ the run time license information.
Simultaneously, a timer starts.
If the license server is still unreachable after one week, the license number is half of the license number
in license files.
If the license server is still unreachable after eight weeks, the license number is the number of demo
licenses.
Corrective Action
If the license server unreachable alarm appears, use the rtrv-lics output to determine how many days
license server has been unreachable.
Follow these steps to resolve this problem.
Step 1 Go to the machine where the license server is running (see the first line of the license file for the server
hostname).
Step 2 Enter the ps -ef |grep lmgrd command to see whether the license server daemon is running.
a. If the license server is not running, enter the /opt/CiscoMGC/local/reload_lics.sh command to
restart the license server.
b. If the license server still fails to start, check the /opt/CiscoMGC/var/log/flexlm_server.log for
detailed information or contact Cisco TAC.
c. If the license server is running, but the active Cisco PGW 2200 Softswitch is running on a separate
machine, ensure that the Cisco PGW 2200 Softswitch machine can reach the IP address of the
license server machine.
LIF BER
This alarm occurs when the Cisco PGW 2200 Softswitch detects an excessive bit error ratio from a frame
alignment signal. Any source of electrical noise might cause this alarm; for example, a degraded
transmission line, degraded line connectors, or a high-voltage electrical source that is located in
proximity to a line.
Corrective Action
To correct the problem, isolate the source by testing the connections and transmission line for the
identified component. When you have identified the source, resolve as necessary.
