Disabling and Enabling LLDP on an Interface

LLDP is disabled globally on all supported interfaces. You must enable LLDP globally to allow a device
to send LLDP packets. However, no changes are required at the interface level.
You can configure the interface to selectively not to send and receive LLDP packets with the
no lldp transmit and no lldp receive commands.
If the interface is configured as a tunnel port, LLDP is automatically disabled.
Note
To disable LLDP on an interface, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface interface-id
Step 3
Switch(config)# no lldp transmit
Step 4
Switch(config)# no lldp receive
Step 5
Switch(config)# end
Step 6
Switch(config)# copy running-config

Switch# configure terminal
Step 2
Switch(config)# interface interface-id
Step 3
Switch(config)# lldp transmit
