I believe you want to know about the guest pass for the user's to connect with the guest WLAN.
ZoneDirector 1200 can support up to 4,000 DPSK users and guest passes, and up to 4,000 concurrently connected clients. ZoneDirector 3000 can support up to 10,000 total DPSK users and guest passes, and up to 10,000 concurrently connected clients. ZoneDirector 5000 can support up to 20,000 guest passes and 10,000 DPSKs, and up to 20,000 concurrently connected clients. When the maximum number of users that ZoneDirector supports has been reached, additional clients attempting to connect will be refused.
