TPLINK-LLDP-MIB

Manages TP-Link switch LLDP neighbor discovery global settings and per-port advertisement control.

TPLINK-LLDP-MIB is a TP-Link vendor-specific MIB for configuring the Link Layer Discovery Protocol (IEEE 802.1AB) on managed switches, covering global enable state and per-port advertisement/reception control along with transmit timers. It's a configuration MIB for a discovery protocol, so its primary monitoring value is confirming the software feature is active as expected on the ports where topology visibility is needed. Enabling/disabling LLDP per port and checking transmit interval/hold-time settings lets an administrator validate that neighbor information, reported via the companion TPLINK-LLDPINFO-MIB, will be current and reliable, and because TP-Link's own documentation is sparse, administrators often load the module into a TPLINK-LLDP-MIB MIB Browser first just to see the exact object names and enumerations before scripting any polling. It implements the IEEE 802.1AB standard, complementing rather than replacing the standard LLDP-MIB where TP-Link's implementation differs. It's deployed on TP-Link managed switches in any network relying on LLDP for automated topology discovery or IP-phone/PoE negotiation.

An administrator checks the global LLDP admin state and per-port transmit-enable objects to confirm LLDP advertisements are active on all uplink and access ports. Verifying the configured transmit interval and hold multiplier ensures neighbor timeout on a management console occurs at the expected rate. A port unexpectedly showing LLDP disabled would explain why a downstream device isn't appearing in the neighbor table reported by TPLINK-LLDPINFO-MIB.
