Parameters
type: Specifies the type of detection packets.
• nd—ND packets.
• icmpv6—ICMPv6 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 the user idle timeout in the range of 60 to 3600 seconds. The default is 180 seconds.
When the timeout expires, online detection of portal users is restarted.
Usage guidelines
After online detection of portal users is enabled on the interface, the device periodically sends detection
packets of the specified type to login 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.
• If the device receives a reply, it stops sending detection packets. Then the device restarts the idle
timer and waits for the packets from the user.
Direct authentication and re-DHCP authentication support both ND detection and ICMPv6 detection.
Cross-subnet authentication only supports ICMPv6 detection.
If firewall policies on the access device filter out ICMPv6 packets, ICMPv6 detection might fail and result
in the logout of portal users. Make sure the access device does not block ICMPv6 packets before you
enable ICMPv6 detection on an interface.
Examples
# Enable online detection of IPv6 portal users on interface GigabitEthernet 2/1/1. Configure the
detection type as ICMPv6, the maximum number of detection attempts as 5, the detection interval as 10
seconds, and the user idle timeout as 300 seconds.
