HP 6600 Security Configuration Manual page 155

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.
Configuration procedure
To configure stateful failover:
Step
1. Enter system view.
2. Enter interface view.
3. Specify the portal group to
which the portal service
backup interface belongs.
4. Return to system view.
5. Specify the device ID in
stateful failover mode.

Remarks
N/A
N/A
By default, the portal service
backup interface does not belong
to any portal group.
The portal service backup
interfaces on the two devices for
stateful failover must belong to the
same portal group.
N/A
By default, the device operates in
stand-alone mode, and thus has no
device ID configured.
