xStack® DGS-3620 Series Managed Switch Web UI Reference Guide CHAP, and MS CHAPv2. Redirect State Redirect Destination Use the drop-down menu to enable or disable JWAC Redirect. When the redirect quarantine server is enabled, the unauthenticated host will be redirected to the quarantine server when it tries to access a random URL. When the redirect JWAC login page is enabled, the unauthenticated host will be redirected to the JWAC login page in the Switch to finish authentication. When redirect is disabled, only access to the quarantine server and the JWAC login page from the unauthenticated host are allowed, all other web access will be denied. NOTE: When enabling redirect to the quarantine server, a quarantine server must be configured first. Use the drop-down menu to select the destination before an unauthenticated host is redirected to either the Quarantine Server or the JWAC Login Page. Redirect Delay Time (0-10) Enter the Delay Time before an unauthenticated host is redirected to the Quarantine Server or JWAC Login Page. Enter a value between 0 and 10 seconds. A value of 0 indicates no delay in the redirect. RADIUS Authorization Use the drop-down menu to enable or disable RADIUS Authorization. Local Authorization Use the drop-down menu to enable or disable Local Authorization. Error Timeout (5-300) Enter the time in second for the Quarantine Server Error Timeout. When the Quarantine Server Monitor is enabled, the JWAC Switch will periodically check if the Quarantine works okay. If the Switch does not receive any response from the Quarantine Server during the configured Error Timeout, the Switch then regards it as not working properly. Enter a value between 5 and 300 seconds. Monitor Use the drop-down menu to enable or disable the JWAC Quarantine Server Monitor. When Enabled, the JWAC Switch will monitor the Quarantine Server to ensure the server is okay. If the Switch detects no Quarantine Server, it will redirect all unauthenticated HTTP access attempts to the JWAC Login Page forcibly if the Redirect is enabled and the Redirect Destination is configured to be a Quarantine Server. URL Enter the JWAC Quarantine Server URL. If the Redirect is enabled and the Redirect Destination is the Quarantine Server, when an unauthenticated host sends the HTTP request packets to a random Web server, the Switch will handle this HTTP packet and send back a message to the host to allow it access to the Quarantine Server with the configured URL. When a computer is connected to the specified URL, the quarantine server will request the computer user to input the user name and password to complete the authentication process. Update Server IP Enter the Update Server IP address. Mask Enter the Server IP net mask. Port Enter the port number used by the Update Server.
