DSP Operational State Notifications

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.

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:

•CISCO-DSP-MGMT-MIB

•DSP Operational State Notification

•Benefits of DSP Operational State Notifications

CISCO-DSP-MGMT-MIB

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

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-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.

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

Enabling DSP Operational State Notifications from the CLI

Perform this task to enable DSP operational state notifications from the CLI.

SUMMARY STEPS

1. enable

2. configure terminal

3. snmp-server enable traps [notification type][vrrp]

4. end

5. exit

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

snmp-server enable traps [notification-type][vrrp]

Example:

Router(config)# snmp-server enable traps dsp oper-state

Enables the generation of DSP notifications made up of the DSP ID that indicates which DSP is affected and the operational state that indicates whether the DSP has failed or recovered.

Step 4 

end

Example:

Router(config)# end

Returns the device to privileged EXEC mode.

Step 5 

exit

Example:

Router# exit

Returns the device to user EXEC mode.

Enabling DSP Operational State Notifications Using an SNMP Application

Perform this task to enable DSP operational state notifications using your SNMP application.

SUMMARY STEPS

1. setany -v2c 1.4.198.75 test cdspEnableOperStateNotification.0 -i 1

DETAILED STEPS

Step 1 setany -v2c 1.4.198.75 test cdspEnableOperStateNotification.0 -i 1

This SNMP command sets the enable operation state notification object identifier (OID) to true.

After entering this command, the system returns the following response: cdspEnableOperStateNotification.0 = true(1).

Configuration Examples for DSP Operational State Notifications

•Enabling DSP Operational State Notifications Using the CLI: Example

•Enabling DSP Operational State Notifications Using an SNMP Application: Example

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 1.4.198.75, 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 1.4.198.75, 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 1.4.198.75 test cdspEnableOperStateNotification.0 -i 1

The application shows the following response:

cdspEnableOperStateNotification.0 = true(1)
