Attribute Meaning
Channel Bandwidth
The channel size used by the radio for RF transmission.
Selecting multiple channel bandwidths will increase registration and re-
registration times.
Cyclic Prefix Scan
The cyclic prefix for which AP scanning is executed.
AP Selection Method Operators may configure the method by which a scanning SM selects an AP.
By default, AP Selection Method is set to “Optimize for Throughput”, which
has been the mode of operation in releases prior to 12.0.3.1.
Power Level: AP selection based solely on power level
OR
Optimize for Throughput: AP selection based on throughput optimization –
the selection decision is based on power level (which affects the modulation
state), channel bandwidth (which affects throughput) and number of SM
registrations to the AP (which affects system contention performance).
Color Code 1 to 10 Color code allows you to force the SM to register to only a specific AP, even
where the SM can communicate with multiple APs. For registration to occur,
the color code of the SM and the AP must match. Specify a value from 0 to
254.
Color code is not a security feature. Instead, color code is a management
feature, typically for assigning each sector a different color code. The default
setting for the color code value is 0. This value matches only the color code
of 0 (not all 255 color codes).
SMs may be configured with up to 10 color codes. These color codes can be
tagged as Primary, Secondary, or Tertiary, or Disable. 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 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 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.
