We are using Cisco AP1231 Access Point in our office to provide the wireless LAN and we are using LEAP for authentication. Now, we would like to use WPA (with PEAP authentication) for the new notebooks. Is it possible for a single AP to use LEAP and WPA in a same VLAN? The SSID can be same or different. Thanks.
If you're asking if Cisco LEAP is supported by WPA WPA2, yes, like all EAP types, Cisco LEAP can be used with WPA and WPA2 networks.
But if you're asking if LEAP and PEAP works on the same AP to the same VLAN, no you can not do it. There are several differences between them that you can check on the following link at the title "EAP TYPE COMPARISONS":
