Cisco Cisco IOS Software Release 12.4(4)T

Familiarity with the CISCO-DSP-MGMT-MIB and Simple Network Management 
Protocol (SNMP). 

To enable DSP operational state notifications when a DSP fails and when it recovers, you should 
understand the following concepts:

The CISCO-DSP-MGMT-MIB monitors DSP resources and status.

A DSP notification consists of a DSP ID that indicates which DSP is affected and an operational state 
that indicates whether the DSP has failed or recovered.

When this feature is configured using the snmp-server enable traps dsp oper-state command, a 
notification is generated when a single DSP fails instead of after all DSPs have failed. For example, a 
DSP fails, and you lose your voice calls. In a DSP failure notification, the problem is identified. If no 
DSP failure notification is generated, a network management station (NMS) has to poll the router for 
configuration and status information to diagnose the problem. 

The DSP Operational State Notifications feature enables the generation of notifications when DSP 
failure and recovery events occur. These notifications help facilitate troubleshooting and lessen 
downtime because an NMS does not have to poll the router for configuration and status information to 
diagnose the problem..

DSP operational state notifications can be configured in two ways. To configure these notifications, 
perform one of the following tasks:
