Cisco Wireless LAN Controller Configuration Guide

OL-17037-01

Chapter 11      Configuring Radio Resource ManagementWireless Device Access

Configuring RRM

Using the CLI to View RF Group Status

Follow these steps to view the status of the RF group using the CLI.

Step 1

Enter 

show advanced 802.11a group

 to see which controller is the RF group leader for the 802.11a RF 

network. Information similar to the following appears:

Radio RF Grouping

  802.11a Group Mode............................. AUTO

  802.11a Group Update Interval.................. 600 seconds

  802.11a Group Leader........................... 00:16:9d:ca:d9:60

 

802.11a Group Member......................... 00:16:9d:ca:d9:60

  802.11a Last Run............................ 594 seconds ago

This text shows the details of the RF group, specifically whether automatic RF grouping is enabled for 
this controller, how often the group information is updated (600 seconds by default), the MAC address 
of the RF group leader, the MAC address of this particular controller, and the last time the group 
information was updated.

Note

If the MAC addresses of the group leader and the group member are identical, this controller is 
currently the group leader.

Step 2

Enter 

show advanced 802.11b group

 to see which controller is the RF group leader for the 802.11b/g 

RF network.

Configuring RRM

The controller’s preconfigured RRM settings are optimized for most deployments. However, you can 
modify the controller’s RRM configuration parameters at any time through either the GUI or the CLI.

Note

You can configure these parameters on controllers that are part of an RF group or on controllers that are 
not part of an RF group.

Note

The RRM parameters should be set to the same values on every controller in an RF group. The RF group 
leader can change as a result of controller reboots or depending on which radios hear each other. If the 
RRM parameters are not identical for all RF group members, varying results can occur when the group 
leader changes.

Using the GUI to Configure RRM

Using the controller GUI, you can configure the following RRM parameters: RF group mode, transmit 
power control, dynamic channel assignment, coverage hole detection, profile thresholds, monitoring 
channels, and monitor intervals. To configure these parameters, follow the instructions in the subsections 
below.
