   •  Country Channels (default)—RRM channel scanning occurs only on the data channels in the country of operation.
   • DCA Channels—RRM channel scanning occurs only on the channel set used by the dynamic channel assignment algorithm, which by default includes all of the non-overlapping channels allowed in the country of operation. However, you can use the Dynamic Channel Assignment (DCA) page to specify the channel set to be used by DCA.  

7. Choose the type of RRM Neighbor Discover Type:
   • Transparent—Packets are sent as is.
   • Protected—Packets are encrypted.
8. Set the Monitor Mode to enabled state, if required.
9. In the Monitor Intervals(60 to 3600secs) section, set the AP noise interval, AP signal strength interval, AP coverage interval, and AP load interval in terms of seconds and click Apply.

Note: To set all Auto RF radio parameters to the factory defaults, click Reset to Defaults.

In the DCA tab, you can specify the channels that the dynamic channel assignment (DCA) algorithm considers when selecting the channels to be used for RRM scanning:

1. Choose a Channel Assignment Mode to specify the DCA mode:
   • Automatic(default) —Causes the device to periodically evaluate and, if necessary, update the channel assignment for all joined APs.
   • Freeze —Causes the device to evaluate and update the channel assignment for all joined APs. If you choose this option, you get to view the Invoke Channel Update Once. Click Invoke Channel Update Once to apply the RRM data successfully.
   • Off —Turns off DCA and sets all AP radios to the first channel of the band, which is the default value. If you choose this option, you must manually assign channels on all radios.

2. From the Interval drop-down list, choose the interval that tells how often the DCA algorithm is allowed to run. The default interval is 10 minutes.
3. From the AnchorTime drop-down list, choose a number to specify the time of day when the DCA algorithm must start. The options are numbers between 0 and 23 (inclusive) representing the hour of the day from 12:00 a.m. to 11:00 p.m.
4. Check the Avoid Foreign AP Interference check box to cause the device’s RRM algorithms to consider 802.11 traffic from foreign APs (those not included in your wireless network) when assigning channels to lightweight APs, or uncheck it to disable this feature. For example, RRM may adjust the channel assignment to have access points avoid channels close to foreign APs. By default, this feature is in enabled state.
5. Check the Avoid Cisco AP Load check box to cause the device’s RRM algorithms to consider 802.11 traffic from Cisco lightweight APs in your wireless network when assigning channels. For example, RRM can assign better reuse patterns to access points that carry a heavier traffic load. By default, this feature is in disabled state.
6. Check the Avoid Non-802.11a Noise check box to cause the device’s RRM algorithms to consider noise (non-802.11 traffic) in the channel when assigning channels to lightweight APs. For example, RRM may have APs avoid channels with significant interference from non-AP sources, such as microwave ovens. By default, this feature is in enabled state.
7. Check the Avoid Persistent Non-WiFi Interference check box to enable the device to ignore persistent non-WiFi interference.
8. From the DCA Channel Sensitivity drop-down list, choose one of the following options to specify how sensitive the DCA algorithm is to environmental changes such as signal, load, noise, and interference when determining whether to change channels:
   • Low —The DCA algorithm is not particularly sensitive to environmental changes. The DCA threshold is 5 dB.
   • Medium (default)—The DCA algorithm is moderately sensitive to environmental changes. The DCA threshold is 15 dB.
   • High —The DCA algorithm is highly sensitive to environmental changes. The DCA threshold is 30 dB.
9. Set the Channel Width as required. You can choose the RF channel width as 20 MHz, 40 MHz, 80 MHz, 160 MHz, or Best. This is applicable only for 802.11a/n/ac (5 GHZ) radio.
10. The Auto-RF Channel List section shows the channels that are currently selected. To choose a channel, check the corresponding check box.
11. In the Event Driven RRM section, check the EDRRM check box to run RRM when CleanAir-enabled AP detects a significant level of interference. If enabled, set the sensitivity threshold level at which the RRM is invoked, enter the custom threshold, and check the Rogue Contribution check box to enter the rogue duty-cycle.
12. Click Apply.

In the TPC tab, you can edit the Transmit Power Control (TPC) parameters:

1. Choose of the following dynamic transmit power assignment modes:
   • Automatic(default)—The transmit power is periodically updated for all APs that permit this operation.
   • On Demand—The transmit power is updated on demand. If you choose this option, you get to view the Invoke Power Update Once. Click Invoke Power Update Once to apply the RRM data successfully.
   • Fixed—No dynamic transmit power assignments occur and values are set to their global default.

2. Enter the maximum and minimum power level assignment on this radio. If you configure maximum transmit power, RRM does not allow any access point attached to the device to exceed this transmit power level (whether the power is set by RRM TPC or by coverage hole detection). For example, if you configure a maximum transmit power of 11 dBm, then no access point would transmit above 11 dBm, unless the access point is configured manually. The range is –10 dBm to 30 dBm.
3. In the Power Threshold field, enter the cutoff signal level used by RRM when determining whether to reduce an access point’s power.

The default value for this parameter varies depending on the TPC version you choose. For TPCv1, the default value is –70 dBm, and for TPCv2, the default value is –67 dBm. The default value can be changed when access points are transmitting at higher (or lower) than desired power levels. The range for this parameter is –80 to –50 dBm.

Increasing this value (between –65 and –50 dBm) causes the access points to operate at higher transmit power rates. Decreasing the value has the opposite effect. In applications with a dense population of access points, it may be useful to decrease the threshold to –80 or –75 dBm in order to reduce the number of BSSIDs (access points) and beacons seen by the wireless clients. Some wireless clients might have difficulty processing a large number of BSSIDs or a high beacon rate and might exhibit problematic behavior with the default threshold.

An RF group is a logical collection of devices that coordinate to perform RRM in a globally optimized manner to perform network calculations on a per-radio basis. An RF group exists for each 802.11 network type. Clustering devices into a single RF group enable the RRM algorithms to scale beyond the capabilities of a single device.

Lightweight APs periodically send out neighbor messages over the air. APs using the the same RF group name validate messages from each other.

1. In the RF Grouping tab, choose a group mode:
   • Automatic(default)—Members of an RF group elect an RF group leader to maintain a master power and channel scheme for the group. The RF grouping algorithm dynamically chooses the RF group leader and ensures that an RF group leader is always present. Group leader assignments can and do change (for instance, if the current RF group leader becomes inoperable or if RF group members experience major changes).
   • Leader—A device as an RF group leader, manually. In this mode, the leader and the members are manually configured and are therefore fixed. If the members are unable to join the RF group, the reason is indicated. The members’ management IP addresses and system name are used to request the member to join the leader. The leader tries to establish a connection with a member every 1 minute if the member has not joined in the previous attempt.
   • Off—No RF group is configured.
