Note 

You cannot remove the flex profile configuration from a site tag if local site is configured on the site tag.
Note 

The no local-site command needs to be used to configure the Site Tag as Flexconnect, otherwise the Flex profile configuration does not take effect.

Step 5

description site-tag-name

Example:

Device(config-site-tag)# description "default site tag"

Adds a description for the site tag.
Step 6

end

Example:

Device(config-site-tag)# end

Exits site tag configuration mode and returns to privileged EXEC mode.
Step 7

show wireless tag site summary

Example:

Device# show wireless tag site summary

(Optional) Displays the number of site tags.

Note 

To view detailed information about a site, use the show wireless tag site detailed site-tag-name command.

  3. ap tag-source-priority source-priority source {ap | filter}
  4. ap tag-source-priority source-priority source {ap | filter}
  5. end
  6. ap tag-sources revalidate

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:

Device> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.
Step 2

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.
Step 3

Step 4

ap tag-source-priority source-priority source {ap | filter}

Example:

Device(config)# ap tag-source-priority 1 source filter

Configures source priority for the filter.

  • Use the filter that was configured by using the ap filter name command.

Note 

It is not mandatory to configure an AP filter, it comes with default priorities.

Device(config)# end

Exits global configuration mode and returns to privileged EXEC mode.
Step 6

ap tag-sources revalidate

Example:

Device# ap tag-sources revalidate

Configuring RF Profile (GUI)

Procedure

Step 1

Choose Configuration > Tags & Profiles > RF.

Step 2

On theRF Profile page, click Add to configure the following:

  • General

  • 802.11

  • RRM

  • Advanced
Step 3

In the General tab, proceed as follows:

  1. Enter a name and description for the RF profile.

  2. Choose the appropriate radio band.

  3. To enable the profile, set the status as Enable.

  4. Click Save & Apply to Device.

Step 4

In the 802.11 tab, proceed as follows:

  1. Choose the required operational rates.

  2. Select the required 802.11n MCS Rates by checking the corresponding check boxes.

  3. Click Save & Apply to Device.

Step 5

In the RRM > General tab, proceed as follows:

  1. Enter the foreign interference threshold between 0 and 100 percent in the Interference field. The default is 10.

  2. In the Clients field, enter the client threshold between 1 and 75 clients. The default is 12.

  3. In the Noise field, enter the foreign noise threshold between –127 and 0 dBm. The default is –70.

  4. In the Utilization percentage field, enter the RF utilization threshold between 0 and 100 percent. The default is 80.

Step 6

In the RRM > Coverage tab, proceed as follows:

  1. Enter the client level in the Minimum Client Level field.

  2. In the Data RSSI Threshold field, enter the actual value in dBm. Value ranges from -60 to -90 dBm and the default value is –80 dBm.

  3. In the Voice RSSI Threshold field, enter the actual value in dBm. Value ranges from -60 to -90 dBm and the default value is –75.

Step 7

In the RRM > TPC tab, proceed as follows:

  1. Enter the power level assignment on this radio in the Maximum Power Level field. 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).

  2. In the Minimum Power Level field, enter the minimum power level assignment on this radio.

  3. In the Power Threshold V1 field, enter the cutoff signal level used by RRM when determining whether to reduce an access point’s power.

Step 8

  1. Check the Avoid AP Foreign AP Interference check box to cause the controller’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.

  2. Choose the appropriate channel width.

  3. In the DCA Channels section, the DCA Channels field shows the channels that are currently selected. To choose a channel, select the appropriate check box. Extended UNII-2 channels in the 802.11a/n/ac band do not appear in the channel list: 100, 104, 108, 112, 116, 132, 136, and 140. To include these channels in the channel list, select the Extended UNII-2 Channels check box.

  4. Click Save & Apply to Device.

Step 9

In the Advanced tab, enter the following information in the High Density Parameters section:

  1. In the Max Clients field, set the maximum number of clients allowed globally.

  2. Use the Multicast Data Rate drop-down to choose the data rate for multicast traffic.

    Choose auto to configure the device to use the radio's default data rate.

  3. Use the Rx SOP Threshold drop-down to set the Receiver Start of Packet Detection Threshold (Rx SOP) to determine the Wi-Fi signal level in dBm at which AP radios will demodulate and decode a packet. The higher the RXSOP level, the less sensitive the radio is and the smaller the receiver cell size will be. Reducing the cell size ensures that clients connect to the nearest access point using highest possible data rates. Choose auto to configure the device to use the radio's default threshold.

Step 10

In the Client Distribution section, enter the following:

  • Load Balancing Window—Enter a value between 1 and 20 to specify the load-balancing window and the number of client associations on the AP with the lightest load.

  • Load Balancing Denial Count—Enter a value between 0 and 10 to specify the number of times the client associations will be rejected for a particular AP.

Step 11

In the High Speed Roam section, check the Mode Enable check box to enable the mode.

Step 12

In the Neighbor Timeout field, enter the neighbor timeout value.

Step 13

From the Client Network Preference drop-down list, choose the client network preference.

Step 14
