Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
SS7 RTE KEY FAIL
This alarm occurs when one or more routing keys for an SS7 signaling service that is associated with an
SG has failed; the signaling service cannot receive some ISUP messages. The maximum number of
routing keys that the associated SG supports might have been exceeded.
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 Ensure that the provisioning settings for the bearer channels that are associated with this SG are correct
by using the procedure that is described in the “Retrieving Provisioning Data” section on page 3-69.
If the configuration data associated with the bearer channels is incorrect, begin a dynamic
reconfiguration session, as described in the “Invoking Dynamic Reconfiguration” section on page 3-66.
If reconfiguration clears the alarm, the procedure is complete. Otherwise, proceed to Step 3.
If the configuration data associated with the bearer channels is correct, then proceed to Step 4.
Step 3 Determine the maximum number of dynamic routing keys that are allowed on the associated SG.
Step 4 Determine how many routing keys the Cisco PGW 2200 Softswitch is using for the affected SG by
adding the number of CICs associated with the SS7 signaling service (ss7sgpath) and the number of SS7
subsystems (ss7sgsubsys).
For example, if 990 CICs and 10 SS7 subsystems were associated with the SG, then the Cisco PGW 2200
Softswitch would be using 1000 routing keys.
Step 5 Compare the maximum number of routing keys that are allowed to the number of routing keys being
used. If the number of routing keys being used is greater, proceed to Step 6. Otherwise, proceed to
Step 7.
Step 6 Begin a dynamic reconfiguration session to delete the excess routing keys by removing either CICs or
SS7 subsystems from your configuration, using the procedure that is described in the “Invoking Dynamic
Reconfiguration” section on page 3-66.
If deleting excess routing keys clears the alarm, 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.
SS7 SIG SRVC CONFIG FAIL
This alarm occurs when the identified SS7 signaling service that is associated with an SG is not
configured correctly.
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”
