Blocked Channels
The following scenarios show how to define a blocked-channels list,
which tells the auto-channel selection algorithm the channels to skip
when selecting the best channel. In practical terms, the behavior is
the opposite of the channel plan where channels are explicitly
allowed.
Non-Overlapping Channels On The 2.4GHz Band
Description
In this example, the 2.4 GHz radio controller will be configured to use
auto-channel selection with channel plan 1,6,11. This configuration
is very common because this is the largest list of non-overlapping channels on
the 2.4 GHz band, ensuring the AP will not cause adjacent-channel interference.
Scenario
Non-Radar Channels On The 5GHz Band
Description
In this example, the 5 GHz radio controller will be configured to use
auto-channel selection with channel plan ${allowed_channels}. This configuration is
used to avoid selecting radar channels (which require at least 1 minute of CAC before they
start working): ${blocked_channels}.
