Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
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 Retrieve the current DNS properties by logging in to the active Cisco PGW 2200 Softswitch, starting an
MML session, and entering the prov-rtrv:dnsparam:“all” command:
The system returns a response like the following:
MGC-01 - Media Gateway Controller 1999-12-30 14:27:48
M RTRV
"session=test:dnsparam"
/*
*.DnsCacheSize = 500
*.DnsKeepAlive = 30
*.DnsPolicy = HIERARCHY
*.DnsQueryTimeout = 1000
*.DnsServer1 = 172.22.1.1
*.DnsServer2 = 143.83.1.1
*DnsTTL = 3600
*/
Note the value of the *.DnsServer1 and *.DnsServer2 parameters.
Step 3 Begin a dynamic reconfiguration session to select new DNS servers for your system, entering their IP
addresses in the *.DnsServer1 and *.DnsServer2 parameters, using the procedure that is described in the
“Invoking Dynamic Reconfiguration” section on page 3-66.
If this alarm occurs repeatedly despite selecting new DNS servers, then proceed to Step 4.
Step 4 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.
SIP: OOS
This alarm occurs when an IP link used by the SIP is out of service.
Corrective Action
To correct the problem, attempt to restore the IP link to service using the procedure that is described in
the “Setting the Service State of an IP Link” section on page 6-105.
SIP Service Fail Over
This alarm occurs in response to the failure of switch interfaces, because of either a physical failure or
an administrative shutdown.
