Chapter 11 Configuring Authentication Types
Configuring Authentication Types
Note When you configure TKIP-only cipher encryption (not TKIP + WEP 128 or TKIP + WEP 40) on any
radio interface or VLAN, every SSID on that radio or VLAN must be set to use WPA or CCKM key
management. If you configure TKIP on a radio or VLAN but you do not configure key management on
the SSIDs, client authentication fails on the SSIDs.
Configuring Authentication Types
This section describes how to configure authentication types. You attach configuration types to the
access point’s SSIDs. See the “Configuring Multiple SSIDs” section on page 7-4 for details on setting
up multiple SSIDs. This section contains these topics:
• Assigning Authentication Types to an SSID, page 11-10
• Configuring Authentication Holdoffs, Timeouts, and Intervals, page 11-16
• Creating and Applying EAP Method Profiles for the 802.1X Supplicant, page 11-17
