11. Select the block status, which is a way to quickly and temporarily control a captive
portal during unexpected events, such as denial of service attacks:
• Disable: The blocking function is disabled. You cannot quickly block the captive
portal.
• Enable: The captive portal is blocked.
• Not Blocked: The captive portal is not blocked. The default is Not Blocked.
12. From the Group menu, select an existing captive portal user group for the captive
portal.
All users who belong to the group are permitted to access the network through the
captive portal.
This option is available only if you select Local or RADIUS from the Verification
menu.
13. In the Idle Timeout field, enter the number of seconds that the switch waits before
terminating an idle session and logging out the user.
The range is from 0 to 900 seconds. The default is 0 seconds, which means that the
time-out is not enforced.
14. From the User Logout menu, specify if an authenticated client can log out from the
captive portal and network:
• Enable: A user can deliberately log out from the captive portal and network.
• Disable: A user cannot log out from the captive portal and network, causing the
connection status to remain authenticated until the captive portal deauthenticates
the user, for example because idle time-out or session time-out period is exceeded.
15. If the verification mode is RADIUS (that is, you select RADIUS from the Verification
menu), specify the IP address of the RADIUS server in the Radius Auth Server field.
16. From the Redirect Mode menu, specify if newly authenticated clients are redirected
to a URL:
• Enable: Authenticated clients are redirected to a URL that you can specify in the
Redirect URL field.
• Disable: Authenticated clients are not redirected and the default locale “welcome”
is used. The default is Disable.
17. In the Redirect URL field, specify the URL to which newly authenticated clients must
be redirected.
The maximum length for the URL is 512 alphanumeric characters. The default URL
is http://
/v1/security/captive_portal/cp_welcome.html.
This option is available only if you select Enable from the Redirect Mode menu.
