device.

 

 

 

 

 

2

Port ID

Identifies the specific port that transmitted the

Mandatory

 

 

LLDP frame. When the device does not advertise

 

 

 

MED TLV, this field displays the port name of the

 

 

 

port; when the device advertises MED TLV, this

 

 

 

field displays the MAC address of the port.

802.1, IEEE 802.3, IETF, as well as individual

 

 

 

software and equipment vendors, to define TLVs

 

 

 

that advertise information to remote device.

 

 

 

 

 

Optional TLVs are grouped into two categories including basic management TLV and Organizationally-specific TLV.

1) Basic Management TLV

A set of TLVs considered to be basic to the management of the network stations are required for all LLDP implementations.

2) Organizationally Specific TLV

Different organizations have defined various TLVs. For instance, Port VLAN ID TLV, Port and Protocol VLAN ID TLV, VLAN Name TLV And Protocol Identity TLV are defined by IEEE 802.1, while MAC/PHY Configuration/Status TLV, Power Via MDI TLV, Link Aggregation TLV and Maximum Frame TLV are defined by IEEE 802.3. Some specific TLVs are for LLDP-MED protocol, such as LLDP-MED Capabilities TLV, Network Policy TLV, Extended Power-via-MDI TLV, Hardware Revision TLV and so on.
