Enabling or Disabling MAC LLC
When the ring becomes operational, the FDDI interface exchanges Logical Link
Control (LLC) Protocol Data Units (PDUs) between the MAC and the local LLC
entity. You can enable or disable transmission of PDUs on an interface.
Site Manager: LLC Data Enable parameter: page A-10
Note: Enabling or disabling this parameter does not affect transferring and
receiving MAC or SMT frame types.
