Airtime Fairness Mode The airtime fairness feature provides equal access to all clients on the wireless medium, regardless of client type, capability, or operating system, thus delivering uniform performance to all clients. This feature prevents the clients from monopolizing resources. You can configure airtime fairness mode parameters through the Instant UI or the CLI. In the Instant UI 1. For Airtime fairness mode configuration, specify any of the following values under the RF > ARM > Show advanced options tab: Table 54: Airtime Fairness Mode-Configuration Parameters Parameter Description Default Access Select this option to provide access based on client requests. When Air Time Fairness is set to default access, per-user and per-SSID bandwidth limits are not enforced. Fair Access Select this option to allocate Airtime evenly across all the clients. Preferred Access Select this option to set a preference where 802.11n clients are assigned more airtime than 802.11a/11g. The 802.11a/11g clients get more airtime than 802.11b. The ratio is 16:4:1. 2. Click OK. In the CLI (Instant AP)(config)# arm (Instant AP)(ARM)# air-time-fairness-mode {| | (Instant AP)(ARM)# end (Instant AP)# commit apply Client Match The ARM client match feature continually monitors a client's RF neighborhood to provide ongoing client band steering and load balancing, and enhanced W-IAP reassignment for roaming mobile clients. This feature supersedes the legacy band steering and spectrum load balancing features, which unlike client match, do not trigger W-IAP changes for clients already associated to a W-IAP. In addition to this, the Client Match feature provides the smartphone handoff assist function which helps smartphones to switch between 3G and 4G networks when the Wi-Fi connectivity is poor. The W-IAP monitors the Received Signal Strength Indicator (RSSI) of the smartphone and checks if it remains under the threshold connectivity strength for a certain duration and deauthenticates the client. Legacy 802.11a/b/g access points do not support the client match feature. When client match is enabled on 802.11n-capable access points, the client match feature overrides any settings configured for the legacy band steering, station handoff assist, or load balancing feature. 802.11ac-capable access points do not support the legacy band steering, station handoff assist, or load balancing settings; so these access points must be managed using client match.

Client Match
The ARM client match feature continually monitors a client's RF neighborhood to provide ongoing client band
steering and load balancing, and enhanced W-IAP reassignment for roaming mobile clients. This feature
supersedes the legacy band steering and spectrum load balancing features, which unlike client match, do not
trigger W-IAP changes for clients already associated to a W-IAP. In addition to this, the Client Match feature
provides the smartphone handoff assist function which helps smartphones to switch between 3G and 4G
networks when the Wi-Fi connectivity is poor. The W-IAP monitors the Received Signal Strength Indicator (RSSI)
of the smartphone and checks if it remains under the threshold connectivity strength for a certain duration
and deauthenticates the client.
Legacy 802.11a/b/g access points do not support the client match feature. When client match is enabled on
802.11n-capable access points, the client match feature overrides any settings configured for the legacy
band steering, station handoff assist, or load balancing feature. 802.11ac-capable access points do not
support the legacy band steering, station handoff assist, or load balancing settings; so these access points
must be managed using client match.
