Description: Huawei VRRP snooping MIB for monitoring VRRP advertisement traffic on access switches without active VRRP participation.

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.

What Is HUAWEI-VRRP-SNOOPING-MIB?

HUAWEI-VRRP-SNOOPING-MIB is a Huawei-proprietary module for passively monitoring VRRP (Virtual Router Redundancy Protocol) advertisement traffic on Layer 2 access switches that do not themselves participate in VRRP. It exposes snooped information about observed VRRP groups/virtual-router IDs, the currently snooped master's address, and the ingress port/VLAN on which VRRP advertisements were seen. Its monitoring purpose is to give visibility into gateway-router hardware/software status without direct SNMP access to those routers: it reveals which router currently holds the VRRP master role and can flag master failover events as they happen, as well as VRRP traffic arriving on an unexpected port. It is fundamentally derived from the standard VRRP protocol (RFC 5798) and complements the standard VRRP-MIB deployed on the actual VRRP-speaking routers. It is typically deployed on Huawei Layer 2 access switches sitting between VRRP-enabled default-gateway routers and end hosts. Engineers can download the HUAWEI-VRRP-SNOOPING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-VRRP-SNOOPING-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An admin would poll a snooped VRRP table (an hwVrrpSnpGroupTable/hwVrrpSnpGroupEntry pattern) recording each observed virtual-router ID, the currently snooped master address, and the ingress port/VLAN. Watching the snooped master address change confirms that VRRP failover occurred correctly after a gateway router was rebooted or lost its uplink. Seeing VRRP advertisements arrive on an unexpected access port would flag a misconfigured or rogue device impersonating the gateway.

What Can Be Monitored

snooped VRRP group/virtual-router ID
observed VRRP master address/state
VRRP advertisement ingress port/VLAN
VRRP master failover events

OIDs

OID symbolic	OID numeric	Type	Access	Description
hwVrrpSnooping	1.3.6.1.4.1.2011.6.142			The mib file is for management of the snooping of VRRP extension. VRRP: Virtual Router Redundancy Protocol, specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN.
hwVrrpSnoopingObject	1.3.6.1.4.1.2011.6.142.1			VrrpSnooping Object.
hwVrrpSnoopingPortTable	1.3.6.1.4.1.2011.6.142.1.1		not-accessible	Indicates the port snooping control table, which is used for adding, deleting, and querying a port for snooping. The index of this table is hwVrrpSnoopingPortIndex.
hwVrrpSnoopingPortEntry	1.3.6.1.4.1.2011.6.142.1.1.1		not-accessible	Indicates the port snooping control table, which is used for adding, deleting, and querying a port for snooping. The index of this entry is hwVrrpSnoopingPortIndex.
I32 hwVrrpSnoopingPortIndex	1.3.6.1.4.1.2011.6.142.1.1.1.1	Integer32	not-accessible	Indicates the port for snooping. Range: -1, 1-16 The NMS issues -1 and the system automatically allocates the index within 1-16 that is not occupied.
I32 hwVrrpSnoopingPortIfIndex	1.3.6.1.4.1.2011.6.142.1.1.1.2	Integer32	read-write	Indicates ifindex of the port for snooping.
ROW hwVrrpSnoopingPortRowStatus	1.3.6.1.4.1.2011.6.142.1.1.1.3	RowStatus	read-create	Indicates the row status. Currently, only createAndGo(4), destroy(6), and active(1) are supported. In creating a port for snooping, hwVrrpSnoopingPortRowStatus needs to be bound and set to createAndGo(4). In deleting a port for snooping, hwVrrpSnoopingPortRowStatus needs to be bound and set to destroy(6). In query, hwVrrpSnoopingPortRowStatus is set to active(1). Options: 1. active(1) -indicates the query operation 2. createAndGo(4) -indicates creating an RRPP domain 3. destroy(6) -indicates deleting an RRPP domain
hwVrrpSnoopingVRouterTable	1.3.6.1.4.1.2011.6.142.1.2		not-accessible	Indicates the virtual router group for adding, deleting and querying snooping. The index of this table is hwVrrpSnoopingVRouterIndex.
