NAME
lanscan — display LAN device configuration and status
SYNOPSIS
lanscan
[-aimnpqv]
[system]
lanscan
[-aimnpqv]
[system
[core]]
# PA only
DESCRIPTION
lanscan
displays the following information about each
LAN
device that has software support on the system:
Active Station Address (also known as Physical Address).
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.
HP DLPI Supported. Indicates whether or not the lan device driver
will work with HP's Common Data Link Provider Interface.
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.
The
system
argument allows substitution for the default value
/stand/vmunix.
On PA systems only, the
core
argument allows substitution for the default value
/dev/kmem.
Options
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 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.
