 device-name

    Supplies the LAN controller device name. The device name has
    the form ddcu where dd is the device code, c is the controller
    designation, and u is the unit number. LAN devices are specified
    as the name of the template device which is unit 0. For example,
    the first DE435 Ethernet device is specified as EWA0, the second
    as EWB0.

    For example, you can specify a DEMNA controller as EXA, EXA0,
    or EXA0:. This refers to the LAN template device, for which is
    maintained most of the device parameters and counters. Also,
    the device name can refer to a device unit representing an
    actual user or protocol. For example, the cluster protocol can
    be started on a device as EWA1. You can specify specific device
    units to view unit-specific parameter information.

    If you do not specify a device name, all devices are displayed.

    If you specify a device name, all matching LAN devices are
    displayed, for example: E to select all Ethernet devices, F
    for FDDI, I for Token Ring, EW to select all Ethernet PCI Tulip
    devices.

                                   NOTE

       If you do not specify a qualifier, the utility displays the
       matching devices without additional information.
