Enters a device into the LAN permanent device database or
    modifies an existing entry. Requires SYSPRV privilege.

                                QUALIFIERS

       See the SET DEVICE command for a list of qualifiers and
       the description of each. Except where noted, the only
       difference is that DEFINE DEVICE applies to entries in
       the LAN permanent device database rather than the volatile
       device database.

    Format

      DEFINE DEVICE  device-name

1  –  Parameter

 device-name

    Supplies the name of a device to be added to the LAN permanent
    device database or an entry to be modified. 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 PCI Ethernet device is specified as EWA0, the second as
    EWB0.

2  –  Examples

    1.LANCP> DEFINE DEVICE EXA0/MOPDLL=(ENABLE,EXCLUSIVE)

      This command defines LAN device EXA0 to enable LANACP MOP
      downline load service in exclusive mode. The setting of the
      KNOWNCLIENTSONLY and SIZE characteristics are not changed. If
      the device entry does not currently exist in the LAN permanent
      device database, these settings are set to the defaults.

    2.LANCP> DEFINE DEVICE/ALL/MOPDLL=NOEXCLUSIVE

      This command sets all LAN devices defined in the LAN permanent
      device database to nonexclusive mode for LANACP MOP downline
      load service.

    3.LANCP> DEFINE DEVICE/ALL/UPDATE/VOLATILE_DATABASE

      This command enters all Ethernet devices into the LAN permanent
      device database and updates the entry to include the current
      parameter values.
