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.
