310 CHAPTER 9: MANAGED ACCESS POINT COMMANDS
set {ap | dap} bias Changes the bias for a MAP. Bias is the priority of one WX switch over
other WX switches for booting and configuring the MAP.
Syntax —
set {ap port-list | dap (dap-num | auto)} bias
{high | low}
 ap port-list — List of ports on which to change the bias for directly
connected MAPs.
 dap dap-num — Number of a Distributed MAP for which to change
the bias.
 dap auto — Configures bias for the MAP configuration template. (See
set dap auto on page 306.)
 high — High bias.
 low — Low bias.
Defaults — The default bias is high.
Access — Enabled.
History —Introduced in MSS Version 3.0. Option auto added for
configuration of the MAP configuration template, MSS Version 4.0.
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.
