Select the Avoid Foreign AP Interference check box to cause the Cisco WLC’s RRM algorithms to consider 802.11 traffic from foreign access points (those not included in your wireless network) when assigning channels to lightweight access points, or unselect it to disable this feature. For example, RRM may adjust the channel assignment to have access points avoid channels close to foreign access points. The default value is selected.

Select the Avoid Cisco AP Load check box to cause the Cisco WLC’s RRM algorithms to consider 802.11 traffic from Cisco lightweight access points in your wireless network when assigning channels, or unselect it to disable this feature. For example, RRM can assign better reuse patterns to access points that carry a heavier traffic load. The default value is unselected.

In the EU countries, outdoor deployments do not support non-DFS channels. Customers based in EU or regions with similar regulations must enable this option or at least have one non-DFS channel in the DCA list even if the channel is not supported by the APs.

In the DCA Channel List area, the DCA Channels text box shows the channels that are currently selected. To choose a channel, select its check box in the Select column. To exclude a channel, unselect its check box.

If you are using Cisco Aironet 1520 series mesh access points in your network, you need to set the 4.9-GHz channels in the 802.11a band on which they are to operate. The 4.9-GHz band is for public safety client access traffic only. To choose a 4.9-GHz channel, select its check box in the Select column. To exclude a channel, unselect its check box.

Select the Enable Coverage Hole Detection check box to enable coverage hole detection, or unselect it to disable this feature. If you enable coverage hole detection, the Cisco WLC automatically determines, based on data received from the access points, if any access points have clients that are potentially located in areas with poor coverage. The default value is selected.

In the Data RSSI text box, enter the minimum receive signal strength indication (RSSI) value for data packets received by the access point. The value that you enter is used to identify coverage holes (or areas of poor coverage) within your network. If the access point receives a packet in the data queue with an RSSI value below the value that you enter here, a potential coverage hole has been detected. The valid range is –90 to –60 dBm, and the default value is –80 dBm. The access point takes data RSSI measurements every 5 seconds and reports them to the Cisco WLC in 90-second intervals.

In the Voice RSSI text box, enter the minimum receive signal strength indication (RSSI) value for voice packets received by the access point. The value that you enter is used to identify coverage holes within your network. If the access point receives a packet in the voice queue with an RSSI value below the value that you enter here, a potential coverage hole has been detected. The valid range is –90 to –60 dBm, and the default value is –75 dBm. The access point takes voice RSSI measurements every 5 seconds and reports them to the Cisco WLC in 90-second intervals.

In the Min Failed Client Count per AP text box, enter the minimum number of clients on an access point with an RSSI value at or below the data or voice RSSI threshold. The valid range is 1 to 75, and the default value is 3.

In the Coverage Exception Level per AP text box, enter the percentage of clients on an access point that are experiencing a low signal level but cannot roam to another access point. The valid range is 0 to 100%, and the default value is 25%.

2. In the TPC area, configure a custom TPC power threshold for either Version1 or Version 2 of TPC.

   Note	Only one version of TPC can be operable for RRM on a given controller Version 1 and Version 2 are not interoperable within the same RF profile. If you select a threshold value for TPCv2 and it is not in the chosen TPC algorithm for the RF profile, this value will be ignored.

3. In the Coverage Hole Detection area, configure the voice and data RSSI.

4. In the Coverage Exception text box, enter the number for clients.

5. In the Coverage Level text box, enter the percentage.

6. In the Profile threshold for Traps area, enter the interference percentage, number of clients, noise level, and utilization percentage.

9. In the High-Speed Roam area, enter the neighbor timeout factor.

10. In the DCA area, choose one of the following channel width options to specify the channel bandwidth supported for all 802.11n and 802.11 ac radios in the 5-GHz band:

    • 20 MHz—The 20-MHz channel bandwidth (default)
    • 40 MHz—The 40-MHz channel bandwidth
    • 80 MHz—The 80-MHz channel bandwidth

11. In the DCA area, the DCA Channels text box shows the channels that are currently selected. To choose a channel, select its check box in the Select column. To exclude a channel, unselect its check box. The channel numbers listed are applicable only for that particular RF profile.

    The ranges are as follows:

    • 802.11a—36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140, 149, 153, 157, 161, 165, 190, 196
    • 802.11b/g—1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

    The defaults are as follows:

    • 802.11a—36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140, 149, 153, 157, 161
    • 802.11b/g—1, 6, 11

In the High Density tab, do the following:

1. In the High Density Parameters area, enter the maximum number of clients to be allowed per AP radio and the client trap threshold value.

2. In the Multicast Parameters area, choose the data rates from the Multicast Data Rates drop-down list.

In the Client Distribution tab, do the following:

1. In the Load Balancing area, enter the client window size and the denial count.

   The window size becomes part of the algorithm that determines whether an access point is too heavily loaded to accept more client associations:

   load-balancing window + client associations on AP with the lightest load = load-balancing threshold

   In the group of access points accessible to a client device, each access point has a different number of client associations. The access point with the lowest number of clients has the lightest load. The client window size plus the number of clients on the access point with the lightest load forms the threshold. Access points with more client associations than this threshold is considered busy, and clients can associate only to access points with client counts lower than the threshold.

   The denial count sets the maximum number of association denials during load balancing.

2. In the Band Select area, select or unselect the Probe Response check box.

   Note	The Band Select configurations are available only for the 802.11b/g RF profiles.

3. In the Cycle Count text box, enter a value that sets the number of suppression cycles for a new client. The default count is 2.

4. In the Cycle Threshold text box, enter a time period in milliseconds that determines the time threshold during which new probe requests from a client from a new scanning cycle. The default cycle threshold is 200 milliseconds.

5. In the Suppression Expire text box, enter a time period after which the 802.11 b/g clients become new and are subject to probe response suppression.

6. In the Dual Band Expire text box, enter a time period after which the dual band clients become new and are subject to probe response suppression.

7. In the Client RSSI text box, enter the minimum RSSI for a client to respond to a probe.
