Which two configuration settings must be modified in the Cisco WLC to achieve this configuration?

FlexConnect APs have already been deployed in a branch office for local switching. Currently the WLAN in the large auditorium is proposed to change to a high-density design and thus some low data rates are proposed to be disabled while keeping the data rates in other areas under the same Cisco WLC.

Which two configuration settings must be modified in the Cisco WLC to achieve this configuration? (Choose two.)

A. RF Profiles

B. Mobility Groups

C. FlexConnect Groups

D. AP Groups

E. Fape profile.

Explanation:

From:

Cisco Wireless LAN Controller Configuration Guide, Release 7.4 -Configuring FlexConnect Groups [Cisco Wireless LAN Controller Software] -Cisco http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_010001111.html

AP Groups

After you create up to 512 WLANs on the Cisco WLC, you can selectively publish them (using access point groups) to different access points to better manage your wireless network.

After all access points have joined the Cisco WLC, you can create up to 150 access point groups and assign up to 16 WLANs to each group. Each access point advertises only the enabled WLANs that belong to its access point group. The access point does not advertise disabled WLANs in its access point group or WLANs that belong to another group.

The Cisco WLC creates the default-group access point group and automatically populates it with the first 16 WLANs (WLANs with IDs 1 through 16, or fewer if 16 WLANs are not configured). This default group cannot be modified (you cannot add WLANs to it and you cannot delete WLANs from it). It is dynamically updatedwhenever the first 16 WLANs are added or deleted. If an access point does not belong to an access point group, it is assigned to the default group and uses the WLANs in that group. If an access point joins the Cisco WLC with an undefined access point group name, the access point keeps its group name but uses the WLANs in the default-group access point group.

RF Profiles

RF Profiles allows you to tune groups of APs that share a common coverage zone together and selectively change how RRM will operates the APs within that coverage zone.

For example, a university might deploy a high density of APs in an area where a high number of users will congregate or meet. This situation requires that you manipulate both data rates and power to address the cell density while managing the co-channel interference. In adjacent areas, normal coverage is provided and such manipulation would result in a loss of coverage.

Using RF profiles and AP groups allows you to optimize the RF settings for AP groups that operate in different environments or coverage zones. RF profiles are created for the 802.11 radios. RF profiles are applied to all APs that belong to an AP group, where all APs in that group will have the same profile settings.

The RF profile gives you the control over the data rates and power (TPC) values.

What is a Mobility Group?

A. A Mobility Group is a group of Wireless LAN Controllers (WLCs) in a network with the same Mobility Group name. These WLCs can dynamically share context and state of client devices, WLC loading information, and can also forward data traffic among them, which enables inter-controller wireless LAN roaming and controller redundancy. Refer to the Configuring Mobility Groups section of Cisco Wireless LAN Controller Configuration Guide, Release 7.0 for more information.

FlexConnect Groups

To organize and manage your FlexConnect access points, you can create FlexConnect Groups and assign specific access points to them.

All of the FlexConnect access points in a group share the same backup RADIUS server, CCKM, and local authentication configuration information. This feature is helpful if you have multiple FlexConnect access points in a remote office or on the floor of a building and you want to configure them all at once. For example, you can configure a backup RADIUS server for a FlexConnect rather than having to configure the same server on each access point.
