Link Session Termination

The user or the remote station can end DLC FDDI.

The user or the remote station can end DLC FDDI in the following ways:

  • The user can cause normal termination by issuing a DLC_HALT_LS command to the DLC FDDI device manager. The DLC_HALT_LS command causes the primary or combined station to initiate a disconnect (DISC) packet sequence.
  • Receive inactivity can be optioned to cause termination. This is useful in detecting a loss of attachment in the middle of a session.
  • The remote station can cause termination by sending a DISC command packet as a primary or combined station.
Note: Protocol violations and resource outages can cause abnormal termination.
