■ both raise its transmit power and open its data rates (see Figure 12-68)
Sometimes you lower radios’ transmit power so that closely grouped RPs can
support higher data rates within their relatively small coverage areas. When an
RP radio raises its transmit power to take over a failed neighbor’s coverage area,
it can no longer support high data rates for all stations (some are too far away).
In this case, you should remember to configure the radio to open its data rates
as well as raise its power. (This is the default action.)
■ take no action
Remember that radios are always neighbors to each other. However, you might
want one radio to respond to the failure of a second radio, but you might not
want the second radio to respond to the failure of the first radio. For example,
the second radio might be in a more important location. When editing the second
radio, configure it to take no action.
Note If you configure a dedicated detector to take action when a neighbor fails, that radio
automatically changes to single-channel detector mode when it takes the action so
that it can support wireless stations.
Keep these considerations in mind as you configure the action:
■ You configure an action for a radio, not for a neighbor. The radio must take the
same action no matter which of its neighbors fails.
■ You can configure one action for one radio and another for one of its neighbors.
For example, you might configure one radio to open its data rates, but you might
configure the neighbor to take no action.
To configure the self-healing action, complete these steps:
1. Select Special Features > Self Healing and click the Neighbor Details tab. In
the upper-right corner of the screen, verify that neighbor recovery is enabled.
2. Select the radio for which you want to define the action, and then click the Edit
button. The Edit Neighbors screen is displayed. (See Figure 12-69.)
