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.

Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface interface-id
Step 3
Switch(config)# no lldp transmit
