Description: IEEE 802.1 MIB for Multiple Instance Registration Protocol (MIRP) providing GARP/MRP protocol instance management.

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 IEEE8021-MIRP-MIB?

IEEE8021-MIRP-MIB is a standards-based IEEE 802.1 MIB module defining objects for the Multiple I-SID Registration Protocol (MIRP), part of the IEEE 802.1Qbe extension used in Provider Backbone Bridged Networks (PBBN). It exposes per-port protocol state and configuration data such as protocol enablement status, backbone VLAN ID (BVID) associations, and destination selector settings for I-SID registration. In monitoring terms it is used chiefly to check the operational/administrative enabled status of MIRP on each bridge port and confirm per-port configuration consistency across a PBB network, rather than to monitor traditional hardware health metrics like temperature or CPU. It depends on and extends the broader IEEE 802.1Q Bridge MIB framework and PBB (802.1ah) constructs referenced by the BVID and I-SID objects. It is typically deployed in carrier-grade Ethernet switches and provider backbone bridges within service-provider network cores where I-SID-based service instances must be registered and disseminated. Engineers implementing or auditing this functionality typically reference the IEEE8021-MIRP-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in IEEE8021-MIRP-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.

Supported Devices

Provider Backbone Bridge (PBB) switches
carrier Ethernet switches
vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

An administrator polling ieee8021MirpV2PortTable/ieee8021MirpV2PortEntry can check ieee8021MirpV2PortEnabledStatus per port to confirm MIRP is active where expected. Cross-referencing ieee8021PbbMirpEnableStatus, ieee8021PbbMirpBvid, and ieee8021PbbMirpDestSelector reveals whether a backbone VLAN's I-SID registration is misconfigured or disabled on a port, which would show up as unreachable service instances. The ieee8021MirpV2Conformance/Compliances/Groups objects define conformance requirements rather than live monitoring data.

What Can Be Monitored

MIRP protocol enabled status per port
PBB MIRP enable status
backbone VLAN ID (BVID) association
destination selector configuration
plug-and-play (PNP) enable state

OIDs

OID symbolic	OID numeric	Type	Access	Description
T/F ieee8021PbbMirpEnableStatus	1.3.111.2.802.1.1.9.1.1.1.7	TruthValue	read-write	The administrative status requested by management for MIRP. The value true(1) indicates that MIRP should be enabled on this component, on all ports for which it has not been specifically disabled. When false(2), MIRP is disabled on all ports. This object affects all MIRP Applicant and Registrar state machines. A transition from false(2) to true(1) will cause a reset of all MIRP state machines on all ports. The value of this object MUST be retained across reinitializations of the management system.
VLA ieee8021PbbMirpBvid	1.3.111.2.802.1.1.9.1.1.1.8	VlanIdOrNone	read-write	The B-VID to which received MIRPDUs are to be assigned, or 0, if they are to be sent on the CBP PVID.
INT ieee8021PbbMirpDestSelector	1.3.111.2.802.1.1.9.1.1.1.9	INTEGER	read-write	An enumerated value specifying what destination_address and vlan_identifier are to be used when the MIRP Participant transmits an MIRPDU towards the MAC relay entity: cbpMirpGroup (1) Use the Nearest Customer Bridge group address from Table 8-1 with the MIRP B-VID. cbpMirpVlan (2) Use the Nearest Customer Bridge group address from Table 8-1 with the Backbone VLAN Identifier field from the Backbone Service Instance table. cbpMirpTable (3) Use the Default Backbone Destination and Backbone VLAN Identifier fields from the Backbone Service Instance table. The value of this object MUST be retained across reinitializations of the management system.
T/F ieee8021PbbMirpPnpEnable	1.3.111.2.802.1.1.9.1.1.1.10	TruthValue	read-write	A Boolean value specifying the administrative status requested by management for attaching a MIRP Participant to a PNP if and only if this system is a Backbone Edge Bridge (BEB): true(1) The BEB is to attach a MIRP Participant to exactly one Port, either a management Port with no LAN connection external to the BEB, or a PNP. false(2) No MIRP Participant is to be present on any PNP (or on the MAC Relay-facing side of a CBP). The value of this object MUST be retained across reinitializations of the management system.
IEE ieee8021PbbMirpPnpPortNumber	1.3.111.2.802.1.1.9.1.1.1.11	IEEE8021BridgePortNumberOrZero	read-only	The Bridge Port Number of the Provider Network Port (PNP) that has an associated MIRP Participant, or 0, if no Bridge Port has an associated MIRP Participant. This object indexes an entry in the Bridge Port Table. The system SHALL ensure that either ieee8021PbbMirpPnpPortNumber contains 0, or that the indexed ieee8021BridgeBasePortType object contains the value providerNetworkPort(3).

ieee8021MirpV2PortTable	1.3.111.2.802.1.1.23.1.1		not-accessible	A table that contains controls for the Multiple I-SID Registration Protocol (MIRP) state machines for all of the Ports of a Bridge.
ieee8021MirpV2PortEntry	1.3.111.2.802.1.1.23.1.1.1		not-accessible	Each entry contains the MIRP Participant controls for one Port.
T/F ieee8021MirpV2PortEnabledStatus	1.3.111.2.802.1.1.23.1.1.1.1	TruthValue	read-create	The state of MIRP operation on this port. The value true(1) indicates that MIRP is enabled on this port, as long as ieee8021PbbMirpEnableStatus is also enabled for this component. When false(2) but ieee8021PbbMirpEnableStatus is still enabled for the device, MIRP is disabled on this port. If MIRP is enabled on a VIP, then the MIRP Participant is enabled on that VIP's PIP. If MIRP is enabled on none of the VIPs on a PIP, then the MIRP Participant on the PIP is diabled; any MIRP packets received will be silently discarded, and no MIRP registrations will be propagated from the PIP. A transition from all VIPs on a PIP false(2) to at least one VIP on the PIP true(1) will cause a reset of all MIRP state machines on this PIP. If MIRP is enabled on any port not a VIP, then the MIRP Participant is enabled on that port. If MIRP is disabled on a non-VIP port, then MIRP packets received will be silently discarded, and no MIRP registrations will be propagated from the port. A transition from false(2) to true(1) will cause a reset of all MIRP state machines on a non-VIP port. The value of this object MUST be retained across reinitializations of the management system.
