Software User Manual 12/10/09 D-Link Unified Access System Table 225: CP Configuration Field Enable Captive Portal Configuration Name Protocol Mode Verification Mode User Logout Mode Enable Redirect Mode Redirect URL RADIUS Auth Server Idle Timeout Session Timeout Max Up Rate Max Down Rate Max Receive Max Transmit Max Total Description Select the check box to enable the CP. Clear the check box to disable it. This field allows you to change the name of the portal added from the CP Summary page. Choose whether to use HTTP or HTTPs as the protocol for the portal to use during the verification process. • HTTP: Does not use encryption during verification • HTTPS: Uses the Secure Sockets Layer (SSL), which requires a certificate to provide encryption. The certificate is presented to the user at connection time. Select the mode for the CP to use to verify clients: • Guest: The user does not need to be authenticated by a database. • Local: The switch uses a local database to authenticated users. • RADIUS: The switch uses a database on a remote RADIUS server to authenticate users. Select this option to allow an authenticated client to deauthenticate from the network. If this option is clear or the user does not specifically request logout, the client connection status remains authenticated until the CP deauthenticates the user, for example by reaching the idle timeout or session timeout values. Select this option to specify that the CP should redirect the newly authenticated client to the configured URL. If this option is clear, the user sees the locale-specific welcome page after a successful verification. Specify the URL to which the newly authenticated client is redirected if the URL Redirect Mode is enabled. If the verification mode is RADIUS, click the ... button and select the name of the RADIUS server used for client authentications. The switch acts as the RADIUS client and performs all RADIUS transactions on behalf of the clients. To configure RADIUS server information, go to LAN > Security > RADIUS > RADIUS Authentication Server Configuration. Enter the number of seconds a user can remain idle before automatically being logged out. If the value is set to 0 then the timeout is not enforced.The default value is 0. Note: The idle time cannot be enforced in this release for a Wired Captive Portal client due to hardware limitations. Enter the number of seconds to wait before terminating a session. A user is logged out once the session timeout is reached. If the value is set to 0 then the timeout is not enforced. The default value is 0. Enter the maximum speed, in bytes per second, that a client can transmit traffic when using the captive portal. This setting limits the bandwidth at which the client can send data into the network. Enter the maximum speed, in bytes per second, that a client can receive traffic when using the captive portal. This setting limits the bandwidth at which the client can receive data from the network. Enter the maximum number of bytes that a client is allowed to receive when using the captive portal. After this limit has been reached the user will be disconnected. Enter the maximum number of bytes that a client is allowed to transmit when using the captive portal. After this limit has been reached the user will be disconnected. Enter the maximum number of bytes the user is allowed to transfer (sum of bytes transmitted and received). After this limit has been reached the user will be disconnected.
