    Format

      SHOW ACP

1.1  –  Parameters

    None.

1.2  –  Qualifiers

1.2.1    /OUTPUT

       /OUTPUT=file-name

    Creates the specified file and directs output to it.

1.3  –  Example

  LANCP> SHOW ACP
  LANCP/LANACP options:
    Verify is OFF
    OPCOM messages are ENABLED
    DLL packet tracing is DISABLED

      This example shows how LANCP and LANACP are currently
      configured.

2  –  CONFIGURATION

    Displays a list of LAN devices and characteristics on the system.

    Format

      SHOW CONFIGURATION

2.1  –  Parameters

    None.

2.2  –  Qualifiers

2.2.1    /OUTPUT

       /OUTPUT=file-name

    Creates the specified file and directs output to it.

2.2.2    /USERS

    Shows which protocols are using which template device.

3  –  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

3.1  –  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.

3.2  –  Qualifiers

3.2.1    /ALL

    Shows all devices that match device name.

3.2.2    /CHARACTERISTICS

       /CHARACTERISTICS or PARAMETERS

    Displays status and related information about the device.

3.2.3    /CLEAR_COUNTERS

    Clears device counters and internal driver counters after a
    SHOW DEVICE/COUNTERS or SHOW DEVICE/INTERNAL_COUNTERS command.
    Subsequent SHOW commands show the counter values accumulated
    since the clear was done.

    This affects counters displayed by LANCP only.

    See the /RESTORE_COUNTERS to restore counters to the original
    values.

3.2.4    /COUNTERS

    Displays device counters.

3.2.5    /DLL

       /DLL or MOPDLL

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

3.2.6    /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.

3.2.7    /MAP

    Displays the current configuration of the functional address
    mapping table.

3.2.8    /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.

3.2.9    /OUTPUT

       /OUTPUT=file-name

    Creates the specified file and directs output to it.

3.2.10    /RESTORE_COUNTERS

    Restores device counters and internal driver counters prior to
    a SHOW DEVICE/COUNTERS or SHOW DEVICE/INTERNAL_COUNTERS command.

    See the /CLEAR_COUNTERS to clear the counters.

3.2.11    /REVISION

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

3.2.12    /SR_ENTRY

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

3.2.13    /TRACE

    Displays LAN driver trace data.

3.2.14    /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 packets that contain the configuration
    information and displays the configured tags.

    The switch periodically sends GVRP (GARP VLAN Registration
    Protocol) (GARP = Generic Attribute Registration Protocol)
    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.

      On this node, there are two LAN devices, EXA (DEMNA) and
      FXA (DEMFA). MOP downline load service is enabled on EXA in
      exclusive mode.

      Requests are answered only for nodes that are defined in the
      LANACP node database. The image data size in the load messages
      is 1482 bytes. There have been five downline loads, the last
      one occurring on node GALAXY at 10:27. Finally, there are no
      recorded downline loads for FXA, which is currently disabled
      for downline load service.

    Displays information for all nodes in the LAN volatile node
    database. If you specify a node name, all matching nodes are
    selected; for example, A/ALL selects all nodes beginning with A.

6.2.2    /OUTPUT

       /OUTPUT=file-name

    Creates the specified file and directs output to that file. If
    the file extension is .com, the output is in the form of a list
    of DEFINE NODE or SET NODE commands. The resulting command file
    can be used to create the LAN node databases.

      This example shows output from a command issued on a local node
      on which there are three nodes defined (GALAXY, ZAPNOT, and
      CALPAL). CALPAL has issued two load requests:

      o  The first request is the multicast request from CALPAL that
         the local node volunteered to accept.

      o  The second request is the load request sent directly to the
         local node by CALPAL for the actual load data. The elapsed
         time from the second load request to completion of the load
         was 6.65 seconds.
