Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Note This alarm can occur when a provisioning session is active during peak busy hours. If a provisioning
session is active, you might clear the alarm by stopping the provisioning session. For more information
on the MML commands to manage a provisioning session, see the “Provisioning a Cisco PGW 2200
Softswitch” section on page 3-64.
OverResIncomingThreshold
This alarm occurs when the percentage of idle CICs in a trunk group is less than or equal to the
configured threshold.
Corrective Action
This alarm might occur occasionally during periods of congestion. However, if this alarm occurs
repeatedly, you might need to adjust the value of the parameter that controls the percentage of idle CICs
for the affected trunk group. To modify the parameter, 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.Retrieve the current settings for the affected trunk group using the
prov-rtrv:rttrnkgrp:name=“trnkgrp_name” command:
Where:
trnkgrp_name is the name of the affected trunk group.
The system returns a response like the following:
MGC-01 - Media Gateway Controller 2002-09-20 15:38:02.892 EST
M RTRV
"session=NOA_SPAIN:rttrnkgrp"
/*
name type reattempts queuing cutThrough resIncomingPerc
---------- ---- ---------- ------- ---------- ----------
111 1 2 120 2 0
*/
The parameter, ResIncomingPerc, controls the percentage of idle CICs for the trunk group. In the
preceding example, the value is 0.
Step 2 Start a provisioning session, as described in the “Starting a Provisioning Session” section on page 3-64.
Step 3 Use the prov-ed MML command to modify the setting of the resIncomingPerc parameter. For example,
to change the percentage of idle CICs to 30 percent in a trunk group that is called 1000, enter the
prov-ed:rttrnkgrp:name=“1000”, resImcomingPerc=“30” command:
Note The new value for resIncomingPerc takes effect after your provisioning session is activated.
Once the new value is activated, the OverResIncomingThreshold alarm is set or cleared after an
outgoing call is routed over the affected trunk group.
Step 4 Save and activate the provisioning session, as described in the “Saving and Activating your Provisioning
Changes” section on page 3-65.
If the alarm clears, the procedure is complete. Otherwise, proceed to Step 5.
