The Link Layer Discovery Protocol (LLDP) operates on the data link layer. With LLDP, a device can 

store and maintain information about itself and the directly-connected neighbor devices for network 

administrators to check link status.  

LLDP can operate in one of the following modes: 

z 

TxRx: A port in this mode sends and receives LLDPDUs. 

z 

Tx: A port in this mode only sends LLDPDUs. 

z 

Rx: A port in this mode only receives LLDPDUs. 

z 

Disable: A port in this mode does not send or receive LLDPDUs. 

TLVs encapsulated in LLDPDUs fall into these categories: basic TLVs, organizationally specific TLVs, 

and media endpoint discovery (MED) related TLVs.  

Basic TLVs are the base of network device management. Organizationally specific TLVs are defined by 

the standard organization, while MED related TLVs are vendor specific for enhanced device 

management and are optional to LLDPDUs. 

Click Device > LLDP > Global Setup. The Global LLDP Parameters Page opens.

Enable/disable LACP globally. Two options are available: 

z 

Enabled: Enables LLDP globally.

Disabled: Disables LLDP globally.  

By default, LLDP is disabled globally.
