TPLINK-IPV6-SOURCE-GUARD-MIB

Description: Manages TP-Link switch IPv6 source guard port bindings to prevent IPv6 address spoofing.

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.

TPLINK-IPV6-SOURCE-GUARD-MIB is a private TP-Link enterprise MIB that manages IPv6 Source Guard, a switch security feature that filters IPv6 traffic based on verified IP-to-port/MAC bindings to prevent IPv6 address spoofing on access ports. It exposes configuration-category data covering per-port binding tables and source-guard enforcement settings. As a security-feature status MIB, its monitoring role is to confirm the software configuration state -- which ports have source guard enabled and what bindings are currently enforced -- flagging any port where spoofing protection has been disabled or where a binding entry is missing or stale, rather than reporting on hardware health. IPv6 Source Guard typically depends on IPv6 Neighbor Discovery snooping (see TPLINK-NDSNOOPING-MIB) to populate its binding table, giving it an implicit dependency on that companion module. It is deployed on TP-Link managed switches in dual-stack or IPv6 access-layer networks where address spoofing protection is required. Engineers can download the TPLINK-IPV6-SOURCE-GUARD-MIB file directly to load it into their MIB browser.

No sample object names were provided, but based on the module's stated purpose an admin would poll a per-port IPv6 source guard binding table to confirm each active client's IPv6 address is bound to the correct port and MAC address, revealing any port with source guard disabled or an unexpected/missing binding that could indicate a spoofing attempt or misconfiguration.
