Disabling and Enabling LLDP on an Interface

LLDP is enabled by default on all supported interfaces to send and to receive LLDP information.

Note If the interface is configured as a tunnel port, LLDP is automatically disabled.

Beginning in privileged EXEC mode, follow these steps to disable LLDP on an interface.

Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Specify the interface on which you are disabling LLDP, and enter
		interface configuration mode.
Step 3
	no lldp transmit	No LLDP packets are sent on the interface.
Step 4
	no lldp receive	No LLDP packets are received on the interface.
Step 5
	end	Return to privileged EXEC mode.
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.
