NAME
lanscan — display LAN device configuration and status
DESCRIPTION
lanscan
displays the following information about each
LAN
device and VLAN interface that have 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.
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
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
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.
