    DESCRIPTION

        transport connections to all DLSw partners, (3) it

        disconnects all local DLC connections, and (4) it stops

        processing all DLC connection set-up traffic.

        Since these are destructive actions, the user should

        query the circuit and transport connection tables in

        advance to understand the effect this action will have.

        Changing the value from inactive to active causes DLSw

        to come up in its initial state, i.e., transport
