Stopping DLCTOKEN Link Sessions

The user or the remote station can be stopped by the token-ring data link control (DLCTOKEN):

• Issue a DLC_HALT_LS command. This command will cause the primary or combined station to initiate a disconnect (DISC) packet sequence.
• Sending a DISC command packet as a primary or combined station.
• Receiving an inactivity timeout can stop a DLCTOKEN link session. This action is useful in detecting a loss of connection in the middle of a session.

Note: Abnormal stopping is caused by certain protocol violations or by resource outages.
