Receiving LLDPDUs

An LLDP agent that is operating in TxRx mode or Rx mode checks the validity of TLVs carried in every

received LLDPDU. If valid, the information is saved and an aging timer is set for it based on the TTL value

in the TTL TLV carried in the LLDPDU. If the TTL value is zero, the information ages out immediately.

Enabling LLDP

To make LLDP take effect on specific ports, you must enable LLDP both globally and on these ports.

To enable LLDP:
