Maximum subnet size for WLAN

Hi!

 

Usually I never deploy bigger subnets than /24 for my wireless clients but I want to ask you guys about the limits if I use drop broadcast and convert broadcast ARP to unicast feature on my VAPs.

 

With these two features enabled, what's the largest recommended subnet to deploy for wireless only clients?

 

Thanx,

/22 is usually a good size (just over 1000 hosts) and will keep the number of VLANs in your pools down.

With those safeguards in place, we have seen some of our larger customers use a /20.  Please work with your Aruba SE in case you ever need to grow to that large of a space.
