Information About FHRP - HSRP MIB

HSRP MIB Traps

HSRP MIB supports Simple Network Management Protocol (SNMP) Get operations, to allow network devices to get reports about HSRP groups in a network from the network management station.

Enabling HSRP MIB trap support is performed through the CLI, and the MIB is used for getting the reports. A trap notifies the network management station when a device leaves or enters the active or standby state. When an entry is configured from the CLI, the RowStatus for that group in the MIB immediately goes to the active state.

Cisco software supports a read-only version of the MIB, and set operations are not supported.

This functionality supports four MIB tables, as follows:

  • cHsrpGrpEntry table defined in CISCO-HSRP-MIB.my

  • cHsrpExtIfTrackedEntry, defined in CISCO-HSRP-EXT-MIB.my

  • cHsrpExtSecAddrEntry, defined in CISCO-HSRP-EXT-MIB.my

  • cHsrpExtIfEntry defined in CISCO-HSRP-EXT-MIB.my

The cHsrpGrpEntry table consists of all the group information defined in RFC 2281, Cisco Hot Standby Router Protocol; the other tables consist of the Cisco extensions to RFC 2281, which are defined in CISCO-HSRP-EXT-MIB.my.

How to Configure FHRP - HSRP MIB

Enabling HSRP MIB Traps

SUMMARY STEPS

1. enable

2. configure terminal

3. snmp-server enable traps hsrp

4. snmp-server host host community-string hsrp


DETAILED STEPS
  Command or Action Purpose
Step 1 enable


Example:
Device> enable
 

Enables privileged EXEC mode.

  • Enter your password if prompted.

 
Step 2 configure terminal


Example:
Device# configure terminal
 

Enters global configuration mode.

 
Step 3 snmp-server enable traps hsrp


Example:
Device(config)# snmp-server enable traps hsrp
 

Enables the device to send SNMP traps and informs, and HSRP notifications.

 
Step 4 snmp-server host host community-string hsrp


Example:
Device(config)# snmp-server host myhost.comp.com public hsrp
 

Specifies the recipient of an SNMP notification operation, and that HSRP notifications be sent to the host.

 

Configuration Examples for FHRP - HSRP MIB

Example: Enabling HSRP MIB Traps

The following examples show how to configure HSRP on two devices and enable the HSRP MIB trap support functionality. As in many environments, one device is preferred as the active one. To configure a device’s preference as the active device, configure the device at a higher priority level and enable preemption. In the following example, the active device is referred to as the primary device. The second device is referred to as the backup device:

Device A

Device(config)# interface GigabitEthernet 0/0/0
Device(config-if)# ip address 10.1.1.1 255.255.0.0
Device(config-if)# standby priority 200 
Device(config-if)# standby preempt
Device(config-if)# standby ip 10.1.1.3
Device(config-if)# exit
Device(config)# snmp-server enable traps hsrp
Device(config)# snmp-server host yourhost.cisco.com public hsrp

Device B

Device(config)#interface GigabitEthernet 1/0/0
Device(config-if)# ip address 10.1.1.2 255.255.0.0
Device(config-if)#  standby priority 101
Device(config-if)# standby ip 10.1.1.3
Device(config-if)# exit
Device(config)# snmp-server enable traps hsrp
Device(config)# snmp-server host myhost.cisco.com public hsrp
