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 27-2.
Beginning in privileged EXEC mode, follow these steps to enable a TLV on an interface:
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
