Configuring Quality of Service

This command provides the following information:

–

The number of roam reason reports received

–

The number of neighbor list requests received

–

The number of neighbor list reports sent

–

The number of broadcast neighbor updates sent

3. To view the roaming history for a particular client, enter this command:

show client roam-history client_mac

This command provides the following information:

–

The time when the report was received

–

The MAC address of the access point to which the client is currently associated

–

The MAC address of the access point to which the client was previously associated

–

The channel of the access point to which the client was previously associated

–

The SSID of the access point to which the client was previously associated

–

The time when the client disassociated from the previous access point

–

Using the CLI to Debug CCX Client Roaming Issues

If you experience any problems with CCX Layer 2 client roaming, enter this command:

debug l2roam [detail | error | packet | all] {enable | disable}

Configuring Quality of Service

Quality of service (QoS) refers to the capability of a network to provide better service to selected

network traffic over various technologies. The primary goal of QoS is to provide priority including

dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic),

and improved loss characteristics.

The controller supports four QoS levels:

• Platinum/Voice—Ensures a high quality of service for voice over wireless.

• Gold/Video—Supports high-quality video applications.

• Silver/Best Effort—Supports normal bandwidth for clients. This is the default setting.

• Bronze/Background—Provides the lowest bandwidth for guest services.

VoIP clients should be set to Platinum, Gold, or Silver while low-bandwidth clients can be set to Bronze.

You can configure the bandwidth of each QoS level using QoS profiles and then apply the profiles to

WLANs. The profile settings are pushed to the clients associated to that WLAN. In addition, you can

create QoS roles to specify different bandwidth levels for regular and guest users. Follow the instructions

in this section to configure QoS profiles and QoS roles.
