NAME [Toc] [Back]
lanscan - display LAN device configuration and status
SYNOPSIS [Toc] [Back]
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
+ 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 hardware path. Here, # is a number that uniquely identifies a
Options [Toc] [Back]
lanscan recognizes the following command-line options:
Hewlett-Packard Company - 1 - HP-UX 11i Version 2: Sep 2004
-a Display station addresses only. No headings.
-i Display interface names only. No headings.
-l Display information about PPAs that are acquired by APA.
-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.
