wpa-wpa2-mixed - Clients using WPA or WPA2 are accepted for
authentication.
wpa-wpa2-psk-mixed - Clients using WPA or WPA2 with a Pre-
shared Key are accepted for authentication

Interface Configuration (Wireless-VAP)
COMMAND USAGE
◆ The auth command automatically configures settings for each
authentication type, including encryption, 802.1X, and cipher suite. The
command auth open-system disables encryption and 802.1X.
◆ To use WEP shared-key authentication, set the authentication type to
“shared-key” and define at least one static WEP key with the key
command. Encryption is automatically enabled by the command.
◆ To use WEP encryption only (no authentication), set the authentication
type to “open-system.” Then enable WEP with the encryption
command, and define at least one static WEP key with the key
command.
◆ When any WPA or WPA2 option is selected, clients are authenticated
using 802.1X via a RADIUS server. Each client must be WPA-enabled or
support 802.1X client software. The 802.1X settings (see “802.1X
Authentication Commands” on page 169) and RADIUS server details
(see “RADIUS Client Commands” on page 163) must be configured on
the access point. A RADIUS server must also be configured and be
available in the wired network.
◆ If a WPA/WPA2 mode that operates over 802.1X is selected (WPA,
WPA2, WPA-WPA2-mixed, or WPA-WPA2-PSK-mixed), the 802.1X
settings (see “802.1X Authentication Commands” on page 169) and
RADIUS server details (see “RADIUS Client Commands” on page 163)
must be configured. Be sure you have also configured a RADIUS server
on the network before enabling authentication. Also, note that each
client has to be WPA-enabled or support 802.1X client software. A
RADIUS server must also be configured and be available in the wired
network.
◆ If a WPA/WPA2 Pre-shared Key mode is selected (WPA-PSK, WPA2-PSK
or WPA-WPA2-PSK-mixed), the key must first be generated and
distributed to all wireless clients before they can successfully associate
with the access point. Use the wpa-preshared-key command to
configure the key (see “key” on page 215 and “transmit-key” on
page 216).
◆ WPA2 defines a transitional mode of operation for networks moving
from WPA security to WPA2. WPA2 Mixed Mode allows both WPA and
WPA2 clients to associate to a common VAP interface. When the
