2.11 COLORCODEPRIORITYONSM
SMs may now be configured with up to 10 color codes. These color codes can be tagged as
“Primary”, Secondary”, or “Tertiary”. When the SM is scanning for APs, it will first attempt to
register to an AP that matches one of the SM’s Primary color codes. Failing that, the SM will
continue scanning and attempt to register to an AP that matches one of the SM’s Secondary
color codes. Failing that, the SM will continue scanning and attempt to register to an AP that
matches one of the SM’s Tertiary color codes. This is all done in the scanning mode of the SM
and will repeat until a registration has occurred.
Color codes in the same priority group are treated equally. For example, all APs matching one of
the SM’s Primary color codes are analyzed equally. Likewise, this evaluation is done for the
“Secondary” and “Tertiary” priority groups in order. The analysis for selecting an AP within a
priority group is based on various inputs, including signal strength and number of SMs already
registered to each AP.
The first color code in the configuration (Color Code 1) is the pre-Release 9.5 color code. Thus, it
is always a “Primary” Color Code for legacy reasons.
The color codes can be disabled, with the exception of the first color code.
