— Configures bias for the MAP configuration profile. (See

set dap auto on page 339.)
high — High bias.
— Low bias.
low
Defaults — The default bias is high.
Access — Enabled.
History —Introduced in MSS Version 3.0. Option auto added for
configuration of the MAP configuration profile.
Usage — High bias is preferred over low bias. Bias applies only to WX
switches that are indirectly attached to the MAP through an intermediate
Layer 2 or Layer 3 network. A MAP always attempts to boot on MAP
port 1 first, and if an WX switch is directly attached on MAP port 1, the
MAP always boots from it.
If MAP port 1 is indirectly connected to WX switches through the
network, the MAP boots from the switch with the high bias for the MAP.
If the bias for all connections is the same, the MAP selects the switch that
has the greatest capacity to add more active MAPs. For example, if a MAP
is dual homed to two WX4400 wireless LAN switches, and one of the
switches has 50 active MAPs while the other switch has 60 active MAPs,
the new MAP selects the switch that has only 50 active MAPs.
If the boot request on MAP port 1 fails, the MAP attempts to boot over its
port 2, using the same process described above.
MAP selection of a WX switch is sticky. After a MAP selects a WX switch
to boot from, the MAP continues to use that switch for its active data link
even if another switch configured with high bias for the MAP becomes
available.
Examples — The following command changes the bias for a Distributed
MAP to low:
WX4400# set dap 1 bias low
success: change accepted.
