Enabling LEAP
Before you can enable LEAP authentication, your network devices must meet the following
requirements:
• Access points to which your client adapter may attempt to authenticate must use the following
firmware versions or later: 11.23T (access points running VxWorks), Cisco IOS Release 12.2(4)JA
(1100 series access points), Cisco IOS Release 12.2(8)JA (1200 series access points), Cisco IOS
Release 12.3(4)JA (1130 series and BR 1310 series access points), Cisco IOS Release 12.3(7)JA
(1240 series access points), or Cisco IOS Release 12.2(13)JA (350 series access points).
Note To use WPA or CCKM, access points must use Cisco IOS Release 12.2(11)JA or later. To
use WPA2, access points must use Cisco IOS Release 12.3(2)JA or later. To use the
Reporting Access Points That Fail LEAP Authentication feature, access points must use the
firmware versions listed on page 5-22.
• All necessary infrastructure devices (such as access points, servers, etc.) must be properly
configured for LEAP authentication.
Follow the steps below to enable LEAP authentication for this profile.
Step 1 Perform one of the following on the Profile Management (Security) window:
• If you want to enable LEAP without WPA or WPA2, choose 802.1x under Set Security Options and
LEAP in the 802.1x EAP Type drop-down box.
• If you want to enable LEAP with WPA or WPA2, choose WPA/WPA2/CCKM under Set Security
Options and LEAP in the WPA/WPA2/CCKM EAP Type drop-down box.
Note If you want to enable CCKM on the client adapter, you must choose the WPA/WPA2/CCKM
security option, regardless of whether you want the adapter to use WPA or WPA2. The
configuration of the access point to which your client adapter associates determines whether
CCKM will be used with 802.1x, WPA, or WPA2.
Note Refer to the “WPA and WPA2” on page 5-19 for additional information.
