NAME

lanscan - display LAN device conﬁguration and status

SYNOPSIS

lanscan [-ailmnpqv]

DESCRIPTION

lanscan displays the following information about each LAN device that has software support on the sys-

tem:

• 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 Com-

mon 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.

Options

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 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. Two lines per interface. Includes displaying of extended station address

and supported encapsulation methods.

WARNINGS

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.
