Parameters
type: Specifies the type of detection packets.
• arp—ARP packets.
• icmp—ICMP packets.
retry retries: Sets the maximum number of detection attempts, in the range of 1 to 10, and the default is
3. If the device receives no reply from a portal user when this threshold is reached, it logs out the portal
user.
interval interval: Sets a detection interval in the range of 1 to 1200 seconds. The default interval is 3
seconds.
idle time: Sets a user idle timeout in the range of 60 to 3600 seconds. The default is 180 seconds. When
the timeout expires, online detection of IPv4 portal users is restarted.
Usage guidelines
After online detection of IPv4 portal users is enabled on the interface, the device periodically sends the
specified type of detection packets to online portal users to verify if they are online. The detection process
is as follows:
When the device receives no packets from a portal user within the configured idle time, the device sends
detection packets to the user.
• If the device receives no reply from the user after sending detection packets to the user for the
maximum number of times, the device logs out the portal user.
