Step Command Remarks
1. Enter system view. system-view N/A
2. Specify the auto redirection
URL for authenticated portal
users.
portal redirect-url url-string [ wait-time
period ]
By default, an authenticated
user is redirected to the URL
the user typed in the address
bar before portal
authentication.
NOTE:
•
To use this feature for remote Layer 3 portal authentication, the portal server must be the IMC portal
server and the IMC portal server must support the page auto-redirection function.
• The wait-time period option is effective to only local portal authentication.
• When no auto redirection URL is specified for authenticated portal users, an authenticated user is
usually redirected to the URL the user typed in the address bar before portal authentication. However,
with local portal authentication, if the URL a user typed in the address bar before portal authentication
is more than 255 characters, the user cannot be redirected to the page of the URL after passing portal
authentication.
Configuring portal detection functions
Configuring online Layer 3 portal user detection
With online portal user detection enabled on an interface, the device will periodically send probe
packets (ARP requests) to the portal users of the interface to check whether the portal users are still online,
to find out portal users who get offline without logging off.
• If the device receives a reply from a portal user before sending probe packets to the portal user for
the maximum number of times, it considers that the portal user is online and will keep sending
probe packets to the portal user.
• If the device receives no reply from a portal user after sending probe packets to the portal user for
the maximum number of times, it considers that the portal user is offline and will stop sending probe
packets to the portal user and delete the user.
To configure online Layer 3 portal user detection:
