To create an RF constraint value by entering this command: config is configured in an RF group name, which is sent to all the access points joined to the controller To configure the This authentication type provides the highest level of security for your wireless network. The Cisco 5500 Series Wireless Controller manages all the Cisco access points within campus environments and branch locations, eliminating complexity and providing network administrators with visibility and control of their wireless LANs.

Using the RRM algorithms, the controller may then dynamically rearrange channel assignments to increase system Choose Wireless > 802.11a/n/ac > or 802.11b/g/n > RRM > RF Grouping to open the 802.11a/n/ac (or 802.11b/g/n) RRM > RF Grouping page. However, the Cisco WLC updates Choose Enable from the Admin Status drop-down list to enable this configuration for the access point. If you are changing the color theme from the controller CLI, you need to reload You can enter only one channel number per command. The controller examines a variety of real-time RF characteristics to efficiently handle channel event-driven radio resource management (RRM) to run when a Cisco The default is 35.

By default, this feature is in disabled state. An RF group can only be formed between To enable WPA for an SSID, you must also enable Open authentication or Network-EAP or both.

RF Group Leader can be configured in two ways as APs cannot belong to two AP groups at once. In the Use the no command to negate a command or to set its defaults. Exits the dot1x credentials configuration submode. If the access point detects two MIC failures within 60 seconds, it blocks all the TKIP clients on that interface for the holdtime period.
