       /PVC=(vci[,...])
       /[NO]PVC=(vci[,...])

    On Alpha systems, defines the permanent virtual circuit (PVC) to
    be used by a Classical IP over ATM client. This is an optional
    qualifier.

    A list of PVCs is defined for use by CLIP clients. This command
    should be used before enabling the CLIP client. The PVC has to be
    set up manually in the ATM switch.

    The vci is the VCI (Virtual Circuit ID) of the PVC to be used.
