A3COM-HUAWEI-VRRP-EXT-MIB

Description: Extends standard VRRP management with H3C/3Com vendor-specific objects for tracking, preemption delay, and enhanced failover monitoring.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

A3COM-HUAWEI-VRRP-EXT-MIB extends the standard IETF VRRP MIB with vendor-specific objects for H3C/3Com routers and Layer-3 switches, adding capabilities like enhanced failover tracking, preemption delay tuning, and additional state monitoring beyond the base VRRP standard. It exposes configuration and status data related to virtual router redundancy: which router is master, backup timers, tracked interface/link state, and preemption behavior. This is squarely a high-availability monitoring MIB, letting administrators detect unexpected VRRP role changes (master-to-backup failover) that indicate a hardware or link failure on the active router. It explicitly depends on and extends the standard VRRP-MIB (RFC 2787/5798), reusing its virtual router table structure and adding vendor columns. It is deployed on H3C/3Com edge and core routers configured in VRRP redundancy groups for gateway high availability, and the A3COM-HUAWEI-VRRP-EXT-MIB download can be loaded directly into a MIB browser for reference.

No concrete sample objects were provided, so specific table names cannot be grounded to this batch's data; conceptually an administrator would track the extended VRRP virtual router state and preemption-delay objects added by this MIB to detect abnormal failovers, but naming exact object identifiers here would be speculative.
