Configuration Using SAM

X is the Physical Point of Attachment (PPA). This is a numerical
index for the physical card in its class. For LAN devices, the lanscan
command will display the name and PPA number concatenated (such
as lan0) in the Net-Interface NamePPA column.
• lanadmin
lanadmin uses PPA# instead of NMID.
lanadmin supports a new option -B on|off to enable/disable source
routing with Token Ring. -b displays the state of source routing.
Similar functionality was provided by lanconfig until (and including)
10.20.
Executables that rely on NMID have to be changed. Also, if you use
lanconfig to enable/disable Token Ring source routing, you must now
use lanadmin. See the lanadmin manpage for details. Also, driver
start-up scripts must be changed if they rely on NMID to be used by
lanadmin.
• linkloop
linkloop uses PPA# instead of NMID.
Executables that rely on NMID have to be changed. See the linkloop
manpage for details.
• lanconfig
As of 10.30, lanconfig no longer exists. Instead, lanadmin can be
used to enable/disable Token Ring source routing.
The Token Ring rif option (source routing) is now part of the
lanadmin command.
To disable source routing:
/usr/sbin/lanadmin -B off <PPA_number>
To enable source routing:
/usr/sbin/lanadmin -B on <PPA_number>
To display the current setting:
/usr/sbin/lanadmin -b <PPA_number>
By default, source routing is enabled on Token Ring devices. Use the
lanscan command to determine the PPA numbers for LAN devices.
