xStack® DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch correct response. NOTE: This IP does not respond to ARP requests or ICMP packets. HTTP(s) Port (165535) This parameter specifies the TCP port that the JWAC Switch listens to and uses to finish the authenticating process. UDP Filtering This parameter enables or disables JWAC UDP Filtering. When UDP Filtering is Enabled, all UDP and ICMP packets except DHCP and DNS packets from unauthenticated hosts will be dropped. Forcible Logout This parameter enables or disables JWAC Forcible Logout. When Forcible Logout is Enabled, a Ping packet from an authenticated host to the JWAC Switch with TTL=1 will be regarded as a logout request, and the host will move back to the unauthenticated state. RADIUS Protocol This parameter specifies the RADIUS protocol used by JWAC to complete a RADIUS authentication. The options include Local, EAP MD5, PAP, CHAP, MS CHAP, and MS CHAPv2. Redirect State This parameter enables or disables 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 JWAV 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. Redirect Destination This parameter specifies the destination before an unauthenticated host is redirected to either the Quarantine Server or the JWAC Login Page. Redirect Delay Time (0-10) This parameter specifies 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. Quarantine Server Configuration Error Timeout (5300) This parameter is used to set 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 This parameter enables or disables 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 This parameter specifies 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 Configuration Update Server IP This parameter specifies the Update Server IP address. Mask This parameter specifies the Server IP net mask. 140
