lanscan - display LAN device configuration and status
lanscan [-aimnpqv] [system [core]]
lanscan displays the following information about each LAN device and
VLAN interface that has 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
+ DLPI Major Number.
+ Extended Station Address for those interfaces which require
more than 48 bits. This is displayed only when the -v option
+ 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 h/w path. Here '#' is a number that uniquely identifies a VLAN
The arguments system and core allow substitution for the default
values /stand/vmunix and /dev/kmem.

lanscan recognizes the following command-line options:
-a Display station addresses only. No headings.
-i Display interface names only. 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 displays VLAN specific information also - VLAN
id, PPA of physical interface on which VLAN is created,
Priority, ToS, Priority Override, ToS Override and VLAN
name (see vlan(7)).
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.
lanscan was developed by HP.
