        value from active to inactive causes DLSw to take
        the following actions - (1) it disconnects all circuits
        through all DLSw partners, (2) it disconnects all
        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
        connections established and ready to bring up circuits."

        no such restriction.
