H3C S6812 Series Command Reference Manual page 1886

authentication server is not greater than the synchronization detection timeout configured on the
access device.
Deleting a portal authentication server on the device also deletes the user synchronization
configuration for the server.
If you execute this command multiple times, the most recent configuration takes effect.
For information of the users considered as nonexistent on the portal authentication server, the device
deletes the information after the configured detection timeout expires.
If the user information from the portal authentication server does not exist on the device, the device
encapsulates IP addresses of the users in user heartbeat reply packets to the server. The portal
authentication server then deletes the users.
Examples
# Enable portal user synchronization for portal authentication server pts and set the detection
timeout to 600 seconds. If a use has not appeared in the synchronization packets sent by the portal
authentication server for 600 seconds, the access device logs out the user.
