What Is TPLINK-LLDPCOUNT-MIB?
TPLINK-LLDPCOUNT-MIB is a TP-Link enterprise MIB that extends the vendor's TPLINK-LLDP-MIB with LLDP frame and neighbor-event counters for TP-Link managed switches. It defines global scalars under lldpGlobalCount — lldpGlobalCountUpdateTime, lldpGlobalCountNeighborInserted, lldpGlobalCountNeighborDeleted, lldpGlobalCountNeighborDroped, and lldpGlobalCountNeighborAged — alongside a per-interface lldpCountNeighborInfoTable (indexed by ifIndex) exposing lldpNeighborFramesOut/FramesIn, lldpNeighborFramesDiscarded, lldpNeighborFramesInErrors, lldpNeighborAgeOuts, and TLV-level lldpNeighborTlvDiscarded/TlvUnrecognized counters, plus a lldpNeighborChange notification carrying the four global counters. This gives an operator visibility into LLDP protocol health per port — whether neighbor entries are churning, whether frames are being malformed or discarded, or whether unrecognized TLVs are showing up — beyond just the current neighbor snapshot found in the base LLDP-MIB. It depends on TPLINK-LLDP-MIB for the parent OID tree and notification root, and on RFC1213-MIB for ifIndex, and it is deployed on TP-Link managed switches alongside standard LLDP for topology discovery; network administrators can pull the TPLINK-LLDPCOUNT-MIB download to add these counters to their LLDP dashboards.
IPNetwork Monitor allows you to monitor SNMP objects defined in TPLINK-LLDPCOUNT-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 switches (T-series/Omada-managed switch lines)
Monitoring Examples
An operator polls lldpCountNeighborInfoEntry for a given ifIndex to watch lldpNeighborFramesInErrors and lldpNeighborTlvDiscarded alongside lldpNeighborAgeOuts; a port with a climbing FramesInErrors count and repeated age-outs would indicate an unstable or misbehaving LLDP neighbor on that link rather than a genuine topology change.
What Can Be Monitored
- global neighbor insert/delete/drop/age-out counts
- per-port LLDP frames sent/received
- per-port frame discard and error counts
- per-port neighbor age-out counts
- per-port TLV discarded/unrecognized counts
