the transmit key, you must also set WEP Key 3 on the access point to exactly the
same value. The access point does not need to use Key 3 as its transmit key,
however.
Note If you use Network-EAP as the authentication type, you must select key 1 as
the access point’s transmit key. The access point uses the WEP key you enter
in key slot 1 to encrypt multicast data signals it sends to EAP-enabled client
devices. Because the access point transmits the WEP key used for multicast
messages to the EAP-enabled client device during the EAP authentication
process, that key does not have to appear in the EAP-enabled device’s WEP
key list. The access point uses a dynamic WEP key to encrypt unicast
messages to EAP-enabled clients.
Refer to the “Setting Up WEP” section on page 7-9 for instructions on setting the
access point’s WEP keys.
EAP Authentication Requires Matching 802.1X Protocol Drafts
Note This section applies to wireless networks set up to use LEAP. If you do not use
LEAP on your wireless network, you can skip this section.
Wireless client devices use Extensible Authentication Protocol (EAP) to log onto
a network and generate a dynamic, client-specific WEP key for the current logon
session. If your wireless network uses WEP without EAP, client devices use the
static WEP keys entered in the Aironet Client Utilities.
If you use Network-EAP authentication on your wireless network, your client
devices and access points must use the same 802.1X protocol draft. For example,
if the radio firmware on the client devices that will associate with an access point
or bridge is 4.16, then the access point or bridge should be configured to use Draft
8 of the 802.1X protocol. Table 13-4 lists firmware versions for Cisco Aironet
products and the draft with which they comply.
