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
