Description
Use this drop-down menu to either enable or disable JWAC on the Switch.
Enter the JWAC Virtual IP address that is used to accept authentication requests from an
unauthenticated host. The Virtual IP address of JWAC is used to accept authentication
requests from an unauthenticated host. Only requests sent to this IP will get a correct
response.
NOTE: This IP does not respond to ARP requests or ICMP packets.
Enter the Virtual URL used.
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.
Enter the TCP port that the JWAC Switch listens to and uses to finish the authenticating
process.
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.
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.
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.
This parameter specifies the destination before an unauthenticated host is redirected to either
the Quarantine Server or the JWAC Login Page.
This parameter specifies the Delay Time before an unauthenticated host is redirected to the
