Configure WLAN Healing
The wireless controller supports automatic WLAN healing through the following features:
Automatic channel allocation. Enables the wireless controller to distribute an access
point channel automatically across the access points on a floor to reduce interference.
Automatic channel allocation considers interference and the traffic load on the access
point, as well as the wireless mode and bandwidth (also referred to as channel width) to
provide the best channel for the access point.
For information about how to configure automatic channel allocation, including the option
to skip automatic channel allocation during a heavy traffic load or voice activity
, see
Configure Automatic Channel Allocation on page 203.
Automatic transmission power. Automatically determines the optimum transmit power
of an access point based on the coverage requirement.
The access point scans its
neighborhood to determine the RF environment to minimize neighboring access point
interference, leakage across floors, and coverage holes.
For information about how to configure automatic transmission power, see Configure
Automatic Transmission Power on page 193.
When you configure WLAN healing, we recommend the following:
Configure the WLAN self-healing wait time to a value greater than the access point reboot
time, which is usually one minute. Set an appropriate wait time to allow for fluctuations in
the power of nearby access points when access points are rebooted.
The number of neighbors to participate in WLAN self-healing must not be large (three to
four usually suffices in most deployments). Keep the number of participants low to
prevent too many access points from increasing power for a single failed access point.
Configure WLAN Healing for the Basic Profile Group
You can configure WLAN healing for access points in the basic profile group.
To configure WLAN healing for access points in the basic profile group:
1. Open a web browser, and in the browser
’s address field, type the wireless controller’s IP
address.
By default, the IP address is 192.168.0.250.
The wireless controller’s login window opens.
2. Enter your user name and password.
3. Click the Login button.
