Configuring LLDP and LLDP-MED

Configuring LLDP-MED TLVs

By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end device. The device continues to send LLDP-MED packets until it receives LLDP packets only.

Using the lldp interface command, you can configure the interface not to send the following TLVs:

Table 28-2	LLDP-MED TLVs
LLDP-MED TLV		Description
inventory-management		LLDP-MED inventory management TLV
network-policy		LLDP-MED network policy TLV
power-management		LLDP-MED power management TLV

Beginning in privileged EXEC mode, follow these steps to disable a TLV on an interface:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Specify the interface on which you are configuring a LLDP-MED
		TLV, and enter interface configuration mode.
Step 3
	no lldp med-tlv-select tlv	Specify the TLV to disable.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	copy running-config startup-config	(Optional) Save your entries in the configuration file.
