Category: Protocol: LLDP, Standard: IEEE 802

Description: Updated IEEE 802.1 LLDP extension MIB (version 2) defining enhanced TLV objects for VLAN, port protocol, and link aggregation.

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 LLDP-EXT-DOT1-V2-MIB?

LLDP-EXT-DOT1-V2-MIB is the standard IEEE 802.1 Working Group LLDP extension MIB (part of IEEE Std 802.1AB, extending LLDP-V2-MIB) defining organizationally-specific TLV configuration for 802.1Q-related discovery information. Its objects cover per-port TLV transmit-enable flags for port-VLAN ID, VLAN name, protocol-VLAN, protocol identity, VID-usage-digest, and management-VLAN advertisement, alongside local-system tables reporting the port's actual VLAN ID and protocol-VLAN support. As a configuration/protocol-status MIB it lets an administrator confirm which 802.1Q-related TLVs a port advertises via LLDP, useful for automated VLAN/topology discovery tools. It is deployed on network devices implementing IEEE 802.1AB LLDP with 802.1 extension TLVs. Engineers implementing or auditing this functionality typically reference the LLDP-EXT-DOT1-V2-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in LLDP-EXT-DOT1-V2-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

  • Network devices implementing IEEE 802.1AB LLDP (802.1 extension TLVs)

Monitoring Examples

An administrator checks lldpV2Xdot1ConfigVlanNameTxEnable to confirm a port is advertising its VLAN name via LLDP, which downstream network-topology discovery tools rely on.

What Can Be Monitored

  • 802.1Q-related LLDP TLV advertisement configuration
