In this configuration, the MAP sends a boot request on its connected
port. WX switches in the same subnet respond to the MAP. WX switches
with high bias for the MAP respond immediately, whereas WX switches
with low bias for the MAP respond after a brief delay.
If the switches are in another subnet, the MAP uses DNS to locate one of
the switches, and asks the switch to send the IP address of the best WX
to use, based on the bias settings on each switch and the capacity of
each switch to add new active MAP connections. The MAP then requests
its image and configuration files from the best WX.
