8.
The access device sends an authentication reply to the portal server. This reply carries the
EAP-Success message in the EAP-Message attribute.
9.
The portal server notifies the authentication client of the authentication success.
10.
The portal server sends an authentication reply acknowledgment to the access device.
The remaining steps are for extended portal authentication. For more information about the steps, see the
portal authentication process with CHAP/PAP authentication.
Portal stateful failover
Stateful failover supports hot backup of services on two devices. It can be configured on key devices to
avoid service interruptions caused by single point failures. When operating normally, the two devices
synchronize service information. If one device fails, the other device takes over the services.
To implement stateful failover, specify a stateful failover interface on each device and connect the two
stateful failover interfaces through a failover link. For more information about the stateful failover feature,
see High Availability Configuration Guide.

As shown in
service interruption caused by single point failures, deploy two access devices (Gateway A and
Gateway B) and configure the portal stateful failover function so that they back up the portal online user
information of each other through the failover link. If either one (Gateway A or Gateway B) fails, the
other can guarantee the normal data communication of the online portal users and perform portal
authentication for new portal users.
