VMS Help  —  LANCP  SHOW  DEVICE
    Displays information in the volatile device database. If the
    LANACP process is not running, displays a list of current LAN
    devices.

    Format

      SHOW DEVICE  device-name

1  –  Parameter

 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.

2  –  Qualifiers

2.1    /ALL

    Shows all devices that match device name.

2.2    /CHARACTERISTICS

       /CHARACTERISTICS or PARAMETERS

    Displays status and related information about the device.

2.3    /COUNTERS

    Displays device counters.

2.4    /DLL

       /DLL or MOPDLL

    Displays LAN volatile device database information related to MOP
    downline load for the device.

2.5    /INTERNAL_COUNTERS

    Displays internal counters. By default, it does not display zero
    counters. To see all counters, including zero, use the additional
    qualifier /ZERO. To see the debug counters, use the additional
    qualifier /DEBUG.

2.6    /MAP

    Displays the current configuration of the functional address
    mapping table.

2.7    /MESSAGES

    Displays the console messages displayed by the LAN driver as part
    of the LAN driver internal counters. This qualifier is included
    for convenience, to avoid scanning the internal counters to get
    to the message data.

2.8    /OUTPUT

       /OUTPUT=file-name

    Creates the specified file and directs output to it.

2.9    /REVISION

    Displays the current LAN driver and device revision information,
    if available or applicable. Not all LAN drivers maintain revision
    information.

2.10    /SR_ENTRY

    Displays the contents of the current Token Ring source routing
    cache table.

2.11    /TRACE

    Displays LAN driver trace data.

2.12    /VLAN

    Displays a list of IEEE 802.1Q tags that are configured on the
    switch port connected to the specified physical LAN device.
    LANCP listens for the GVRP (GARP (Generic Attribute Registration
    Protocol) VLAN Registration Protocol) packets that contain the
    configuration information and displays the configured tags.

    The switch periodically sends GVRP packets to provide VLAN
    configuration information in compliance with the IEEE 802.1Q
    specification. If GVRP is not configured on the switch, or if the
    LAN device is not connected to a switch, this command displays
    only the list of tags that the VLAN driver has configured.
