authenticating process.
Use the drop-down menu to enable or disable 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.
Use the drop-down menu to choose the RADIUS protocol used by JWAC to complete
a RADIUS authentication. The options include Local, EAP MD5, PAP, CHAP, MS
CHAP, and MS CHAPv2.
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.
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.
Use the drop-down menu to enable or disable RADIUS Authorization.
Use the drop-down menu to enable or disable Local Authorization.
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.
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.
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.
Enter the Update Server IP address.
Enter the Server IP net mask.
Enter the port number used by the Update Server.
