LLDP information is associated with the specific device that sends it. The device itself is
uniquely identified by the receiving party port via chassis ID and port ID values. Multiple LLDP
devices can reside on a single port, using a hub for example, and all of the devices are reported
via MIB. You can enable (Rx-only, TX-only, Rx or Tx) or disable LLDP mode of operation on a
per-port basis.
