Description: Manages TP-Link switch IP multicast routing table entries and forwarding configuration.

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 TPLINK-IPMROUTE-MIB?

TPLINK-IPMROUTE-MIB is a TP-Link private enterprise MIB covering IP multicast routing on TP-Link managed switches/routers, specifically configuration related to PIM (Protocol Independent Multicast) forwarding behavior. It exposes configuration and state data for the multicast routing table: route entries, their associated forwarding interfaces, and related PIM parameters that determine how multicast traffic is replicated and forwarded through the device. Its monitoring relevance is mainly at the software/protocol level — confirming multicast routes are installed and forwarding as expected — rather than physical hardware sensors, though a missing or stale route entry can reveal a control-plane or link problem upstream. It depends on the standard PIM multicast routing model and typically complements a device's unicast routing and interface MIBs. It is deployed in networks running IP multicast applications (e.g., IPTV, video conferencing) where TP-Link switches/routers perform multicast forwarding between VLANs or subnets. Engineers can download the TPLINK-IPMROUTE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TPLINK-IPMROUTE-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.

TP-Link managed switch or router

Monitoring Examples

No specific object or table names were provided in the source excerpt for this module, so exact identifiers cannot be cited. Given its purpose, it would expose a multicast route table keyed by group and source address with associated incoming/outgoing interface indices; an administrator would poll this table to confirm a given multicast group is being forwarded out the correct interfaces. An empty or unexpectedly pruned entry would indicate a PIM neighbor or upstream routing problem rather than a local hardware fault.

What Can Be Monitored

multicast route table entries
forwarding interface assignments
PIM configuration status
route source/group mapping
