R3303-HP 6600/HSR6600 Routers Security Configuration Guide
139
CAUTION:
• Specifying or changing the device ID of a device will log off all online users on the device. Therefore,
perform the confi
g
uration only when necessary and, after the confi
g
uration, save the confi
g
uration and
restart the device.
• When two devices are running in stateful failover mode (one active, the other standby), do not delete the
configured backup source IP addresses. Otherwise, online users on the backup may not be able to
receive packets from the server.
The following matrix shows the feature and router compatibility:

Portal stateful failover Yes Yes No
To implement stateful failover for portal, configure VRRP for traffic switchover, and perform the following
configurations for service backup on each of the two devices that back up each other:
• Specify an interface for backing up portal services, which is referred to as portal service backup
interface in this document, and enable portal on the portal service backup interface. The portal
service backup interface is different from the stateful failover interface. Stateful failover interfaces
only forward state negotiation messages and backup data.
• Specify the portal group to which the portal service backup interface belongs. Be sure to specify the
same portal group for the portal service backup interfaces that back up each other on the two
devices.
• Specify the device ID. Make sure that the device ID of the local device is different from that of the
peer device.
• Specify the backup source IP address for outgoing RADIUS packets as the source IP address for
RADIUS packets that is configured on the peer device, so that the peer device can receive packets
from the server. (This configuration is optional.)
• Specify the stateful failover interface, and enable stateful failover on the interface. For related
configuration, see High Availability Configuration Guide.
After the stateful failover state of the two devices changes from independence to synchronization and the
portal group takes effect, the two devices start to back up the data of online portal users for each other.
Configuration guidelines
• In stateful failover mode, the device does not support re-DHCP portal authentication on the portal
service backup interface.
• In stateful failover mode, if a user on either device is logged out, information about the user on the
other device is deleted, too. You can log off a user on the device or on the portal server. For example,
you can use the cut connection and portal delete-user commands on the device to log off users.
• The AAA and portal configuration must be consistent on the two devices that back up each other.
For example, you must configure the same portal server on the two devices.
