Description: Manages TP-Link switch MLD snooping IPv6 multicast group membership and port filtering.

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-MLDSNOOPING-MIB?

TPLINK-MLDSNOOPING-MIB is a vendor-specific MIB from TP-Link covering MLD (Multicast Listener Discovery) snooping, the IPv6 analogue of IGMP snooping, on TP-Link managed switches. It exposes configuration and status objects controlling which switch ports receive specific IPv6 multicast group traffic based on snooped MLD membership reports. Its monitoring role lets an operator verify MLD snooping is enabled and confirm current multicast group/port membership state, helping detect ports incorrectly included in or excluded from an IPv6 multicast stream. It is a straightforward vendor implementation of the standard MLD protocol concept without deep dependency on other MIBs beyond basic bridge/VLAN conventions. It is deployed on TP-Link managed switches in networks running IPv6 multicast applications where efficient Layer 2 forwarding is required. Engineers can download the TPLINK-MLDSNOOPING-MIB file directly to load it into their MIB browser.

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

TP-Link managed switch

Monitoring Examples

No sample objects were provided, so specific OID names cannot be cited; based on its stated purpose, an operator would poll per-VLAN MLD snooping enable status and multicast group/port membership tables to confirm correct IPv6 multicast forwarding. A port missing from an expected multicast group's membership table would indicate MLD snooping is blocking legitimate IPv6 multicast traffic to that port.

What Can Be Monitored

MLD snooping enable/disable state
IPv6 multicast group membership
per-port multicast forwarding state
