NETGEAR-MRP-MIB

Description: Configures IEEE 802.1Qbe Multiple Registration Protocol applicant and registrar state machines on Netgear switches.

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.

NETGEAR-MRP-MIB is a Netgear private MIB implemented on FastPath-based managed switches to configure the IEEE 802.1Qat/802.1Qav Multiple Registration Protocol (MRP), including MRP applicant and registrar timers per port. It exposes per-port configuration data, join/leave/leave-all timer values and MRP/MMRP enable state, rather than traffic counters, since MRP is a control-plane registration protocol for VLAN and multicast group propagation. While primarily a configuration MIB, it is useful for confirming the software/operational state of the MRP feature on each port (enabled vs. disabled) and for diagnosing registration timing problems that manifest as slow or failed VLAN/group propagation across the switch fabric. It builds directly on IEEE 802.1Q bridge MIB concepts and depends on the underlying dot1dBasePort/ifIndex numbering scheme to identify ports. It is typically deployed in enterprise or industrial Netgear switch stacks using MRP for fast, standards-based dynamic VLAN and stream reservation registration in audio/video bridging or converged Ethernet environments. Engineers can download the NETGEAR-MRP-MIB file directly to load it into their MIB browser.

An engineer would poll agentDot1qPortMrpTable/agentDot1qPortMrpEntry for a given agentDot1qMrpPort to check agentDot1qPortMrpJoinTime, agentDot1qPortMrpLeaveTime, and agentDot1qPortMrpLeaveAllTime, confirming they match standard IEEE defaults. If agentDot1qMrp or agentDot1qMrpMxrp shows the feature disabled on a port that should be running MMRP, VLAN registrations propagated via MRP will fail to reach that port, causing multicast/AVB streams to drop. Abnormally long leave timers found via this table would also explain delayed convergence after a topology change.

Vendor-specific MIB for Netgear Media Redundancy Protocol (MRP); manages redundancy and failover mechanisms on Netgear Ethernet switches and networking devices.
