3Com WL-455 manual „ 802.1x Supplicant Setup

Page 40

„Required — Clients authenticate to a RADIUS server via the access point. Clients are not allowed onto the wired LAN until authentication is successful. If two Radios are installed and WPA is being used, both radios’ security must be set to “WPA authentication over 802.1x” for the WPA key management when 802.1x is Required. If one radio’s security is set to “WPA pre-shared key (PSK)” for WPA key management and the other is “WPA authentication over 802.1x”, then the 802.1x Wireless Setup must be set to “Supported” instead.

When 802.1x is enabled, the broadcast and session key rotation intervals can also be configured. Set these values to force the periodic refresh of broadcast or session keys for each 802.1x client.

First set up the RADIUS authentication for the client on the RADIUS authentication server. (See “RADIUS” on page 31.) Select Supported or Required on the 802.1x Wireless Setup field above. Enter data as described in the following table.

Defines how long the RADIUS server will refresh the primary broadcast key.

Defines how long the RADIUS server will dynamically re-assign a session key to a connected client station.

Defines the time interval in which the Access Point forces a Reauthentication and subsequently re-issues a new session key.

„802.1x Supplicant Setup

802.1x Supplicant provides the access point with the ability to authenticate itself to an 802.1x-enabled switch port. In an environment where network access is controlled via 802.1x, the supplicant makes it possible for the access point to connect to the wired network. The access point assumes the 802.1x authenticator role (if configured properly) after the supplicant has completed. The supplicant authentication method supported is EAP-MD5.

„Enable—Select Enable to start the supplicant authentication process. The supplicant retries the authentication process until it has been successfully authenticated.

„Username—Enter a username to be used for EAP-MD5 authentication.

„Password—Enter a password to be used for EAP-MD5 authentication.

„Confirm Password—Re-enter the password for EAP-MD5 authentication.
