Receiving LLDPDUs
An LLDP-enabled port 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 Time to Live TLV carried in the LLDPDU. If the TTL value is zero, the information ages out
immediately.

LLDP-related configurations made in Ethernet interface view take effect only on the current port, and those made in
port group view take effect on all ports in the current port group. Layer 2 Ethernet interface view is supported only
on SAP modules operating in bridge mode.
Performing basic LLDP configuration
Enabling LLDP
To make LLDP take effect on specific ports, you must enable LLDP both globally and on these ports.
To enable LLDP:
