1. For Airtime fairness mode configuration, specify any of the following values in the RF>ARM >Show
advanced options tab:
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 11n clients are assigned more airtime
than 11a/11g. The 11a/11g clients get more airtime than 11b. The ratio is 16:4:1.

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 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 IAP changes
for clients already associated to an IAP.
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 hand off assist or load balancing features. 802.11ac-capable access points do not support the
legacy band steering, station hand off or load balancing settings, so these access points must be managed using
client match.
When the client match feature is enabled on an IAP, the IAP measures the RF health of its associated clients. In the
current release, the client match feature is supported only within an IAP cluster. If any of the following trigger
conditions is met, clients are moved from one AP to another for better performance and client experience:
l Dynamic Load Balancing: Client match balances clients across IAPs on different channels, based on the client
load on the IAPs and the SNR levels the client detects from an underutilized IAP. If an IAP radio can support
additional clients, the IAP will participate in client match load balancing and clients can be directed to that IAP
radio, subject to the predefined SNR thresholds. For better load balancing, clients are steered from busy
channels to idle channels.
l Sticky Clients: The client match feature also helps mobile clients that tend to stay associated to an IAP despite
low signal levels. IAPs using client match continually monitor the client's RSSI as it roams between IAPs, and
move the client to an IAP when a better radio match can be found. This prevents mobile clients from remaining
associated to an APs with less than ideal RSSI, which can cause poor connectivity and reduce performance for
other clients associated with that IAP.
