Configuring online Layer 3 portal user detection
This feature is available only for the direct and re-DHCP portal authentication configured on a Layer 3
interface.
With online portal user detection enabled on an interface, the firewall 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 firewall 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 firewall 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:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
