 NAME    [Toc]    [Back]
      lanscan - display LAN device configuration and status

 SYNOPSIS    [Toc]    [Back]
      lanscan [-ailmnpqv]

 DESCRIPTION    [Toc]    [Back]
      lanscan displays the following information about each LAN device and
      VLAN interface that have software support on the system:

           +  Hardware Path.

           +  Active Station Address (also known as Physical Address).

           +  Card Instance Number.

           +  Hardware State.

           +  Network Interface ``NamePPA''.   The Network Interface
              ``Name'' and the ``PPA'' (Physical Point of Attachment) number
              are concatenated together.  A single hardware device may have
              multiple ``NamePPA'' identifiers, which indicates multiple
              encapsulation methods may be supported on the device.  For
              Ethernet/IEEE 802.3 links, the ``Name'' lan is used to
              designate Ethernet encapsulation, and snap for IEEE 802.3
              encapsulation.  For other links (FDDI, Token Ring), only the
              lan encapsulation designation is used.

           +  Network Management ID.

           +  MAC Type.

           +  HP DLPI Supported.  Indicates whether or not the lan device
              driver will work with HP's Common Data Link Provider
              Interface.

           +  DLPI Major Number.

           +  Extended Station Address for those interfaces which require
              more than 48 bits.  This is displayed only when the -v option
              is selected.

           +  Encapsulation Methods that the Network Interface supports.
              This is displayed only when the -v option is selected.

      If the interface corresponds to VLAN, then lanscan displays VLAN# as
      its hardware path.  Here, # is a number that uniquely identifies a
      VLAN interface.

    Options    [Toc]    [Back]
      lanscan recognizes the following command-line options:

           -a      Display station addresses only.  No headings.

           -i      Display interface names only.  No headings.

           -l      Display information about PPAs that are acquired by APA.
                   No headings.

           -m      Display MAC types only.  No headings.

           -n      Display Network Managements IDs only.  No headings.

           -p      Display PPA and/or VPPA (PPA associated with a VLAN)
                   numbers only.  No headings.

           -q      Same as -p, except link aggregate PPA's will be followed
                   by a list of LAN interface PPA's that are configured in
                   the corresponding link aggregate. No headings.

           -v      Verbose output.  Multiple lines per interface.  Includes
                   displaying of extended station address and supported
                   encapsulation methods.  If the interface corresponds to
                   VLAN, it also displays VLAN-specific information: VLAN
                   id, PPA of physical interface on which VLAN is created,
                   Priority, ToS, Priority Override, ToS Override, and VLAN
                   name (see vlan(7)).

 WARNINGS    [Toc]    [Back]
      lanscan does not display information about LAN devices that do not
      have software support such as LAN interface cards that fail to bind
      properly at boot-up time.
