The ARM client match feature continually monitors a client's RF neighborhood to provide
ongoing client band steering and load balancing, and enhanced AP reassignment for
roaming mobile clients. This feature supersedes the legacy band steering and spectrum load
balancing features, which unlike client match, do not trigger AP changes for clients already
associated to an AP. 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 AP 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.
Note
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
-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.
