Chapter 3 Cisco PGW 2200 Softswitch Platform Operations
Regular Operations
The following sections provide the procedures for managing call rejection percentages:
• Modifying the MCL Call Reject Settings, page 3-79
• Retrieving the MCL Call Reject Settings, page 3-79
The Cisco PGW 2200 Softswitch raises alarms that are associated with three of the MCLs. The Cisco
PGW 2200 Softswitch raises an alarm as it detects an MCL. These alarms are automatically cleared
when the Cisco PGW 2200 Softswitch exits an MCL. Table 3-15 shows the alarm that corresponds to
each which MCL. For more information on these alarms, see
Cisco PGW 2200 Softswitch Release 9 Messages Reference.
For example, as the Cisco PGW 2200 Softswitch detects a transition in congestion from MC1 to MC2
and back, the raising and clearing of alarms progresses as follows:
1. The OverloadLight alarm is set.
2. The OverloadLight alarm is cleared.
3. The OverloadMedium alarm is set.
4. The OverloadMedium alarm is cleared.
5. The OverloadLight alarm is set.
Note The alarms that correspond to Cisco PGW 2200 Softswitch MCLs create SNMP traps. To identify these
alarms among the SNMP traps, look for the tpAlarmCatName object to contain the name of the alarm
(OverloadLight, OverloadMedium, or OverloadHeavy) and the tpAlarmSet object to indicate whether
the alarm is being set (2) or cleared (1). For more information on the MIBs for the Cisco PGW 2200
Softswitch, see Cisco PGW 2200 Softswitch Release 9 Management Information Base Guide.
