DSP Operational State Notifications
DSP Operational State Notifications
Last Updated: July 24, 2012
The DSP Operational State Notifications feature enables notifications to be generated when digital signaling processor (DSP) failure and recovery events occur. These notifications help facilitate troubleshooting and lessen downtime.
This feature module describes updates to the Cisco DSP Management MIB (CISCO-DSP-MGMT-MIB) for enabling and generating DSP operational state notifications. Also described is how to enable the feature either using the command-line interface (CLI) or by modifying settings at the network management device.

Prerequisites for DSP Operational State Notifications
Information About DSP Operational State Notifications
To enable DSP operational state notifications when a DSP fails and when it recovers, you should understand the following concepts:
DSP Operational State Notification
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-statecommand, 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.
Benefits of DSP Operational State Notifications
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..
How to Enable DSP Operational State Notifications
DSP operational state notifications can be configured in two ways. To configure these notifications, perform one of the following tasks:
Enabling DSP Operational State Notifications from the CLI
Enabling DSP Operational State Notifications Using an SNMP Application
Configuration Examples for DSP Operational State Notifications
Enabling DSP Operational State Notifications Using the CLI Example
The following sample configuration code shows how to enable DSP operational state notifications using the CLI:
Router> enable Router# configure terminal Router(config)# snmp-server enable traps dsp oper-state
The following example shows a typical DSP failure notification:
*Jun 1 02:37:05.720:SNMP:V1 Trap, ent cdspMIBNotificationPrefix, addr 18.104.22.168, gentrap 6, spectrap 2 cdspOperState.37 = 2 entPhysicalEntry.7.37 = DSP (C549) 1/2/0
The following example shows a typical DSP recover notification:
*Jun 1 02:37:10.820:SNMP:V1 Trap, ent cdspMIBNotificationPrefix, addr 22.214.171.124, gentrap 6, spectrap 2 cdspOperState.37 = 1 entPhysicalEntry.7.37 = DSP (C549) 1/2/0
Enabling DSP Operational State Notifications Using an SNMP Application Example
The following sample configuration code shows how to enable DSP operational state notifications from your SNMP application:
In your SNMP application, you type the following command:
setany -v2c 126.96.36.199 test cdspEnableOperStateNotification.0 -i 1
The application shows the following response:
cdspEnableOperStateNotification.0 = true(1)
