Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Step 5 Check the IP connectivity between the Cisco PGW 2200 Softswitch and the associated Cisco BRI voice
gateway.
If the IP connectivity is good, proceed to Step 6.
If the IP connectivity is bad, restore the IP connectivity. If the alarm clears after the IP connectivity is
restored, the procedure is complete. Otherwise, proceed to Step 6.
Step 6 Verify that the provisioning data for your ISDN BRI backhaul connect is correct. To verify the
provisioning data, use the prov-rtrv MML command, as described in the “Retrieving Provisioning Data”
section on page 3-69.
If the provisioning data is correct, proceed to Step 7.
If the provisioning data is not correct, begin a dynamic reconfiguration session, as described in the
“Invoking Dynamic Reconfiguration” section on page 3-66.
Step 7 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.
All ISDN IP Conn Fail
This alarm occurs when communication is lost to all ISDN IP connections. The severity of this alarm is
Critical, which causes an automatic switchover if a standby Cisco PGW 2200 Softswitch is present.
Note The ability to change the severity level of this alarm is implemented in the patch (CSCOgs059) for
Release 9.5(2). The XECfgParm.dat parameter, *.AllISDNLinksFailCausesFailover, now controls the
severity level of this alarm. When this parameter is set to false (the default value), this alarm has a
severity level of Major. If you set this parameter to true, this alarm has a severity level of Critical.
This parameter should be set to true if the Cisco PGW 2200 Softswitches are in separate geographic
locations. You can also set this parameter to true if the system is not processing SS7 calls and you want
your system to perform an automatic switchover if all the ISDN IP connections fail. To change the value
of this parameter, use the procedure that is defined in the “Rebooting Software to Modify Configuration
Parameters” section on page 6-183.
Corrective Action
To correct the problem that this alarm identifies, 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 Verify that the affected media gateways are operating normally, as described in the associated
documentation.
Step 3 Verify that the Ethernet interfaces between the Cisco PGW 2200 Softswitch and the media gateways are
working properly.
