Configuring LLDP, LLDP-MED, and Wired Location Service

Configuring LLDP-MED TLVs

By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end
device. It then sends LLDP packets with MED TLVs, as well. When the LLDP-MED entry has been aged
out, it again only sends LLDP packets.
By using the lldp interface configuration command, you can configure the interface not to send the TLVs
listed in
Table 25-2
LLDP-MED TLV
inventory-management
location
network-policy
power-management
Beginning in privileged EXEC mode, follow these steps to enable a TLV on an interface:
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 lldp med-tlv-select tlv
Step 4 end
Step 5
copy running-config startup-config
This example shows how to enable a TLV on an interface:
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# lldp med-tlv-select inventory-management
Switch(config-if)# end
