You can enable LLDP transmit and receive with the interface ethernet 1/4 command:
switch(config)# interface ethernet 1/4
switch(config-if)# lldp ?
receive Enable LLDP reception on interface
transmit Enable LLDP transmission on interface
Check that the peer supports LLDP.
•
Check if remote peers exist. Check if values exist for a peer's LLDP TLVs.
Use the show lldp interface ethernet 1/4 command.
