5.13 Self Healing

A self-healing network is one that is capable of maintaining the availability of the network under all
circumstances. The network can self-manage in response to the events that occur within the network. Self
heal for WS2000 is provided by the device maintaining a Neighbor Table with entries for each device in its
neighborhood.
Self-healing can be activated from
menu item.
Self-healing consists of two different features, Neighbor Recovery and Interference Avoidance. Neighbor
Recovery uses a Neighbor Table to keep track of all its immediate neighbor portals. Interference Avoidance
detects interference on the channel on which the portal is operating and shifts the portal's channel to an
unused channel in the channel list.
Neighbor Recovery
When enabled, a portal listens to beacons of its neighbors configured in the Neighbor Table. The AP goes
into monitoring mode once it has listened to a set number of beacons from its neighbor. After going into the
monitoring mode, if the AP is not able to listen to the beacons from a neighbor, it considers that particular
neighbor as being down and take appropriate neighbor recovery action as configured in the Neighbor Table.
The following actions can be performed to recover the lost neighbor.
• none - No action is taken to recover
• raise-power - The AP raises its operating power to the maximum power level less the Offset value.
• open-rates - The AP operates with its configured basic and supported rates.
• both - Both the raise-power and open-rates actions are performed.
