Configuring LLDP-MED TLVs

By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end
device. It will then send LLDP packets with MED TLVs as well. When the LLDP-MED entry has been
aged out, it only sends LLDP packets again.
Using the lldp interface configuration command, you can configure the interface not to send the TLVs
listed in
