How can I configure a SSID that able to support WEP & WPA on the WLAN controller? The reason I ask because we are currently have LEAP/WEP and we want to move forward to PEAP/WPA. I have to use the same SSID with 2 type of encryption to support the transition.
Here is an example (using the text commands since I can't post inline screen caps) I run where I do dynamic WEP along with WPA both using radius. When using radius, you can select any of supported EAP types for both the WEP and WPA WLANs.
wlan create 1 MYSSID MYSSID-wep
! create WLAN 1 ssid "MYSSID"
wlan create 2 MYSSID MYSSID-WPA
! create WLAN 2 ssid "MYSSID"
wlan interface 1 vlan86
wlan interface 2 vlan86
Map them to the same interface. You can map them different ones.
wlan session-timeout 1 1800
wlan session-timeout 2 28800
Set up radius re-auth session timeout. Make WEP with 802.1x shorter. if using static WEP (very very insecure), don't do this.
wlan security 802.1X enable 1
We enable 802.1x on our WEP SSID
wlan radius_server auth add 1 1
wlan radius_server auth add 1 2
wlan radius_server auth add 2 1
wlan radius_server auth add 2 2
wlan radius_server auth add 2 3
Assign the 2 wlans to their respective radius servers - primary and backup
