Hello, thanks for your help. We max out at peak time during the day usually around 2,000 wifi users. I'd like to just use a /20 vlan (some room for future growth) for the SSID but is it better to use several /24's in a "vlan pool"? I'm concerned about the exhaustion of the /24s. Currently we have twenty /24's in a vlan pool which should be plenty of space but does the Aruba controller know not to overload a /24 when it is full (if that makes any sense)? For simplicity would it be better to run a /20 with "drop multicast and broadcast" selected? Thanks.
