DESCRIPTION

Basic TLV 

These are the Basic TLV flags

Port ID TLV

The port ID TLV identifies the specific port that transmitted the LLDP frame. 

Port ID Subtype: This shows how the port is identified.

Port ID: This is the ID of the port.

Port 

Description TLV 

 

T

his displays the local port description.

Dot1 TLV 

Port VLAN ID 

TLV

This displays the VLAN ID sent by the IEEE 802.1 Port VLAN ID TLV.

Port-Protocol 

VLAN ID TLV

This displays the IEEE 802.1 Port Protocol VLAN ID TLVs, which indicates whether the 
VLAN is enabled and supported.

Dot3 TLV 

 

MAC PHY 

Configuration & 

Status TLV

The MAC/PHY Configuration/Status TLV advertises the bit-rate and duplex capability of 
the sending 802.3 node. It also advertises the current duplex and bit-rating of the

Size TLV

This displays the maximum supported frame size in octets. 

MED TLV 

LLDP Media Endpoint Discovery (MED) is an extension of LLDP that provides additional 
capabilities to support media endpoint devices. MED enables advertisement and 
discovery of network policies, device location discovery to allow creation of location 
databases, and information for troubleshooting.
