Configuring portal detection functions
Configuring online detection of portal users
Configure online detection of portal users on an interface to find abnormal logouts in time.
If a portal user is idle for the specified period of time (idle time), the device sends detection packets to the
user at intervals (interval interval) to identify whether the user is still online.
• If the device receives no reply from the user after sending detection packets to the user for the
maximum number of times (retry retries), it considers that the portal user is offline and logs out the
user.
• If the device receives a reply, it considers that the portal user is online, and resets the idle timer for
the user. The device repeats the previous procedure to continue detecting the online status of the
user.
IPv4 detection packets can be ARP requests or ICMP requests. IPv6 detection packets can be ND requests
or ICMPv6 requests.
ARP and ND detections apply only to direct and re-DHCP portal authentication. ICMP detection applies
to all portal authentication modes.
