What type of devices are we speaking of? Access points or Client devices? Client Match is "server-side" technology meaning it doesn't matter what type of client you have.
From the documentation:
Legacy 802.11a/b/g devices do not support the client match feature. When you enable client match on 802.11n-capable devices, the client match feature overrides any settings configured for the legacy bandsteering, station handoff assist or load balancing features. 802.11ac-capable devices do not support the legacy bandsteering, station hand off or load balancing settings, so these APs must be managed on using client match.
For clients read the whitepaper
ClientMatch technology works with all clients - including new 802.11ac clients - across all operating systems, without the need for client software. It is available as part of ArubaOS 6.3.9 and higher.
