Configuring LLDP and LLDP-MED
Beginning in privileged EXEC mode, follow these steps to enable LLDP on an interface when it has been
disabled:
Command
Step 1

Step 2
interface interface-id
Step 3
lldp transmit
Step 4
lldp receive
Step 5
end
Step 6
copy running-config startup-config
This example shows how to enable LLDP on an interface.
Switch# configure terminal
Switch(config)# interface GigabitEthernet0/1
Switch(config-if)# lldp transmit
Switch(config-if)# lldp receive
Switch(config-if)# end
Configuring LLDP-MED TLVs
By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end
device. It will then send LLDP packets with MED TLVs as well. When the LLDP-MED entry has been
aged out, it only sends LLDP packets again.
Using the lldp interface command, you can configure the interface not to send the following TLVs:
