Description: Updated IEEE 802.3 LLDP extension MIB (version 2) with enhanced TLV objects for energy-efficient Ethernet and additional PHY attributes.

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-DOT3-V2-MIB?

LLDP-EXT-DOT3-V2-MIB is a vendor-neutral IEEE standards MIB extending the LLDP-V2-MIB with 802.3 organizationally-defined TLVs exchanged between directly-connected Ethernet devices, covering auto-negotiation, MAU (physical layer) type, and Power-over-Ethernet (PoE) power-class information. It exposes local and remote port configuration/data for auto-negotiation capabilities and advertised speed/duplex, the operational MAU type of a port, and per-port PoE power class. Its monitoring value is in detecting link-partner mismatches and PoE issues: comparing local versus discovered-neighbor auto-negotiation settings reveals duplex/speed mismatches, while power-class data confirms PoE devices such as phones or APs are receiving the expected power class. It branches from the base LLDP-V2-MIB (IEEE 802.1AB-2009) discovery framework, on which it fully depends for the underlying neighbor-discovery mechanism. It is deployed on any vendor's Ethernet switches, routers, or NICs that support LLDP for physical-layer neighbor discovery. Engineers implementing or auditing this functionality typically reference the LLDP-EXT-DOT3-V2-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in LLDP-EXT-DOT3-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
Ethernet switch, router, or NIC supporting LLDP (IEEE 802.1AB/802.3)

Monitoring Examples

lldpV2Xdot3LocPortTable/lldpV2Xdot3LocPortEntry exposes lldpV2Xdot3LocPortAutoNegSupported, lldpV2Xdot3LocPortAutoNegEnabled, and lldpV2Xdot3LocPortAutoNegAdvertisedCap, plus the resulting lldpV2Xdot3LocPortOperMauType, letting an admin detect an autoneg/duplex mismatch against a discovered neighbor. lldpV2Xdot3LocPowerTable's lldpV2Xdot3LocPowerPortClass reports the PoE power class advertised on a port, useful for verifying a connected PoE endpoint is getting the expected power budget. lldpV2Xdot3PortConfigTable's lldpV2Xdot3PortConfigTLVsTxEnable shows which 802.3 TLVs a port is actively transmitting, which an admin would check if a neighbor isn't receiving expected auto-negotiation or power information.

What Can Be Monitored

local port auto-negotiation support/enabled
advertised auto-negotiation capabilities
operational MAU type
PoE power class per port
802.3 TLV transmit-enable per port

lldpV2Xdot3MIB	1.3.111.2.802.1.1.13.1.5.4623			The LLDP Management Information Base extension module for IEEE 802.3 organizationally defined discovery information. In order to assure the uniqueness of the LLDP-MIB, lldpV2Xdot3MIB is branched from lldpV2Extensions using OUI value as the node. An OUI/'company_id' is a 24 bit globally unique assigned number referenced by various standards. Unless otherwise indicated, the references in this MIB module are to IEEE 802.1AB-2009. Copyright (C) IEEE (2009). This version of this MIB module is published as Annex F.6.5 of IEEE Std 802.1AB-2009; see the standard itself for full legal notices.
lldpV2Xdot3Objects	1.3.111.2.802.1.1.13.1.5.4623.1
lldpV2Xdot3Config	1.3.111.2.802.1.1.13.1.5.4623.1.1
lldpV2Xdot3PortConfigTable	1.3.111.2.802.1.1.13.1.5.4623.1.1.1		not-accessible	A table that controls selection of LLDP TLVs to be transmitted on individual ports.
lldpV2Xdot3PortConfigEntry	1.3.111.2.802.1.1.13.1.5.4623.1.1.1.1		not-accessible	LLDP configuration information that controls the transmission of IEEE 802.3 organizationally defined TLVs on LLDP transmission capable ports. This configuration object augments the lldpV2PortConfigEntry of the LLDP-MIB, therefore it is only present along with the port configuration defined by the associated lldpV2PortConfigEntry entry. Each active lldpV2Xdot3PortConfigEntry is restored from non-volatile storage (along with the corresponding lldpV2PortConfigEntry) after a re-initialization of the management system.
BIT lldpV2Xdot3PortConfigTLVsTxEnable	1.3.111.2.802.1.1.13.1.5.4623.1.1.1.1.1	Bits	read-write	The lldpV2Xdot3PortConfigTLVsTxEnable, defined as a bitmap, includes the IEEE 802.3 organizationally defined set of LLDP TLVs whose transmission is allowed on the local LLDP agent by the network management. Each bit in the bitmap corresponds to an IEEE 802.3 subtype associated with a specific IEEE 802.3 optional TLV. The bit 0 is not used since there is no corresponding subtype. The bit 'macPhyConfigStatus(0)' indicates that LLDP agent should transmit 'MAC/PHY configuration/status TLV'. The bit 'powerViaMDI(1)' indicates that LLDP agent should transmit 'Power via MDI TLV'. The bit 'unused(2)' is no longer used; this was used for the 'Link Aggregation TLV' in the previous version. The bit 'maxFrameSize(3)' indicates that LLDP agent should transmit 'Maximum-frame-size TLV'. The default value for lldpV2Xdot3PortConfigTLVsTxEnable object is an empty set, which means no enumerated values are set. The value of this object is restored from non-volatile storage after a re-initialization of the management system.
