Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Step 5 Open a dynamic reconfiguration session to modify the routing contexts of the M3UA routing keys, as
described in the “Invoking Dynamic Reconfiguration” section on page 3-66.
If modifying the routing contexts of the M3UA routing keys corrects the problem, the procedure is
complete. Otherwise, proceed to Step 6.
Step 6 Verify that the AS is not shut down on the Cisco ITP. See the documentation for your Cisco ITP for more
information. If the AS is shut down, restart it. Otherwise, proceed to Step 7.
If tending to the AS corrects the problem, the procedure is complete. Otherwise, proceed to Step 7.
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 SUA Assoc Fail
This alarm occurs when all SUA associations transporting SS7 signaling have failed.
Note The XECfgParm.dat parameter, *.AllLinksFailCausesFailover, now 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. For the Cisco PGW 2200 Softswitch to generate this alarm, set the parameter to true,
by using the procedure that is defined in the “Rebooting Software to Modify Configuration Parameters”
section on page 6-183.
If the Cisco PGW 2200 Softswitches are in separate geographic locations, set the value of
*AllLinksFailCausesFailover to true.
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 Verify that the Cisco ITPs are operating normally. See the documentation for your Cisco ITP for more
information.
If ensuring that the Cisco ITPs are operating normally corrects the problem, the procedure is complete.
Otherwise, proceed to Step 3.
Step 3 Verify that the Ethernet interfaces between the Cisco PGW 2200 Softswitch and the Cisco ITPs 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 a Cisco ITP, see the
documentation for the Cisco ITP.
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 4.
