5.6 Configuring Self Healing
The switch supports a feature called Self Healing that enables radios to take corrective action when one or more radios
fail. To enable the feature the user must specify radio neighbors that would self heal if either one goes down. The neighbor
radios do not have to be of the same type. Therefore, an 11bg radio can be the neighbor of a 11a radio and either of them
can self heal when one of them fails.
The switch initiates self healing when it looses communication with the Access Port or when another radio (configured in
detector mode) informs the switch a particular radio is not transmitting beacons.
To configure self-healing on the switch:
1. Select

When enabled, the switch is capable of switching channels on an Access
Port (Automatic Channel Selection) if interference is observed on the
current operating channel.
Displays the average number of retries for a MU to communicate with a
neighbor radio. Define a retry value between 0.0 and 15.0 retry attempts.
Average Retries is a threshold value, when exceeded ACS is initiated.
Set the interval (in seconds) that disables interference avoidance after
detection. The hold time prevents the radio from re-running ACS
continuously.
