Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
If that does not resolve the problem, proceed to Step 4.
Step 4 Verify that the Ethernet interfaces between the Cisco PGW 2200 Softswitch and the associated media
gateway are working properly.
Note For information on verifying the proper operation of an Ethernet interface on the Cisco PGW
2200 Softswitch, see the Sun Microsystems documentation that came with your system. For
information on verifying the proper functioning of an Ethernet interface on the media gateway,
see the documentation for the specific media gateway.
If an element of the Ethernet connection (such as a cable or an Ethernet interface card) is not working
properly, replace it. Otherwise, proceed to Step 5.
Note For information on removing and replacing an Ethernet interface card on the Cisco PGW 2200
Softswitch, see the Sun Microsystems documentation that came with your system. For
information on removing and replacing an Ethernet interface card on the media gateway, see the
documentation for the specific media gateway.
Step 5 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.
NAS: CommsFailure
This alarm occurs when the Cisco PGW 2200 Softswitch cannot communicate with the identified media
gateway.
Corrective Action
To correct the problem, perform the following steps:
Step 1 To collect system data, see the method that is described in the “Collecting System Data for Cisco TAC”
section on page 6-93.
Step 2 Determine whether the affected media gateway is operating. See the documentation for the media
gateway for more information.
If the affected media gateway is not operating, restore it to service. See the documentation for the media
gateway for more information.
If the affected media gateway is operating, proceed to Step 3.
Step 3 Verify that the IP configuration parameters for the Cisco PGW 2200 Softswitch and the affected media
gateway are correct.
Note Use the prov-rtrv MML command, as described in the “Retrieving Provisioning Data” section
on page 3-69, to retrieve the IP configuration information for the Cisco PGW 2200 Softswitch.
See the documentation for the media gateway for information on retrieving the IP configuration
data.
