5.7 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 triggers the self healing action 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 Services > Self Healing from the main menu tree.
The Self Healing page launches with the Configuration tab displayed.
2. Select the Enable Neighbor Recovery checkbox.
Enabling Neighbor Recovery is required to conduct manual neighbor detection.
Subnet Define the subnet address used to route GRE tunnel packets between end-points. Each GRE
tunnel must have a unique subnet to function properly and independent of one another.
Time-to-live Configure the period of time (in seconds) packets are kept alive between tunnel destinations.
The defined interval ensures IP reachability between the tunnel end-points.
