Configuring portal user synchronization

Once the access device loses communication with a portal authentication server, the portal user
information on the access device and that on the portal authentication server might be inconsistent after
the communication resumes. To address this problem, the device provides the portal user synchronization
feature. This feature is implemented by sending and detecting portal synchronization packets, as follows:
1. The portal authentication server sends the online user information to the access device in a
synchronization packet at the user heartbeat interval, which is set on the portal authentication
server.
2. Upon receiving the synchronization packet, the access device compares the users carried in the
packet with its own user list. If a user contained in the packet does not exist on the access device,
the access device informs the portal authentication server to delete the user. The access device
starts the synchronization detection timer (timeout timeout) immediately when a user logs in. If the
user does not appear in any synchronization packet within a synchronization detection interval,
the access device considers the user does not exist on the portal authentication server and logs the
user out.
Portal user synchronization requires a portal authentication server to support the portal user heartbeat
function. Only the IMC portal authentication server supports the portal user heartbeat function. To
implement the portal user synchronization feature, you also need to configure the user heartbeat function
on the portal authentication server. Make sure the user heartbeat interval configured on the portal
authentication server is not greater than the synchronization detection timeout configured on the access
device.
Deleting a portal authentication server on the access device also deletes the user synchronization
configuration for the portal authentication server.
To configure portal user information synchronization:
Step
1. Enter system view.
2. Enter portal
authentication server
view.
3. Configure portal user
synchronization.
