Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
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.
All C7 IP Links Fail
This alarm occurs when communication is lost to all Cisco ITP-Ls of every configured protocol family.
This alarm is critical, and causes an automatic switchover, if a standby Cisco PGW 2200 Softswitch is
present.
Note The XECfgParm.dat parameter, *.AllLinksFailCausesFailover, controls the generation of this alarm.
When this parameter is set to false (the default value), this alarm is not generated when the alarm
condition occurs. If you want the Cisco PGW 2200 Softswitch to generate this alarm, you must set the
parameter to true. See the procedure that is described in the “Rebooting Software to Modify
Configuration Parameters” section on page 6-183.
If your Cisco PGW 2200 Softswitches are in separate geographic locations, you should set the value of
*AllLinksFailCausesFailover to true.
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 If your system is provisioned with destinations that use more than one version of SS7, ensure that this
alarm is configured correctly, as described in the “Verifying Configuration to Support Multiple Versions
of SS7” section on page 6-121.
Step 3 Verify that the Cisco ITP-Ls are operating normally. See the documentation for the Cisco 2800 Series
Integrated Services Routers.
Step 4 Verify that the Ethernet interfaces between the Cisco PGW 2200 Softswitch and the Cisco ITP-Ls are
working properly.
Note To find 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.
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 To find 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 interface card on the Cisco ITP-L, see
Cisco 2800 Series Integrated Services Routers.
