338 CHAPTER 23: WIRELESS ESS COMMANDS
■ 802.1x — 802.1x authentication with WEP.
■ wpa — Wi-Fi Protected Access (WPA and WPA2) are systems to
secure wireless (Wi-Fi) networks. WPA implements the majority of the
IEEE 802.11i standard, and was intended as an intermediate measure to
take the place of WEP while 802.11i was prepared. WPA is designed to
work with all wireless network interface cards, but not necessarily with
first generation wireless access points. WPA2 implements the full
standard, but will not work with some older network cards.
■ wpa-psk — WPA with pre-shared key.
■ wpa2 — Indicates that Wi-Fi Protected Access 2 (WPA) is the selected
WLAN security method. WPA2 with 802.1x authenticates WLAN
users and dynamically generate keys.
■ wpa2-psk — WPA2 with pre-shared key.
■ key — A key must be entered for open-wep, shared-wep,
openshared-wep, wpa-psk and wpa2-psk. A key should not be
entered for 802.1x, wpa and wpa2. See the key command in
Security-Suite ESS Configuration mode for information on the range
of the key size.
■ key-hex — Specifies the entry of a pre-shared key (psk) in hexadecimal
format. (Range: 10-26 characters)
■ key-ascii — Specifies the entry of a pre-shared key (psk) in ASCII
format. (Key length: 5 or 13 characters)
■ encryption-key — Specifies the pre-shared key. See usage guidelines
for the key size range.
■ ssid — The ESS SSID string. (Range: 1-32 characters)
