Configuring stateful failover

Select High Availability > Stateful Failover from the navigation tree to enter the stateful failover

configuration page, as shown in Figure 29. T

he upper part of the page allows you to configure stateful

failover parameters. The lower part of the page displays the current stateful failover configuration and the

failover interface information.

Backup Type

Select whether to support asymmetric path.

• Unsupport Asymmetric Path. When two devices operate properly, traffic passes

through one device to the internal network and goes out through the same

device. The devices work in the master/backup mode, that is, one device

processes services while the other device serves as backup.

• Support Asymmetric Path. When two devices operate properly, traffic can pass

through one device to the internal network and go out through the other device.

That is, the session passes through one of the two devices randomly when

leaving the internal network, thus to achieve load sharing. The two devices

work in the load sharing mode and serve as backup for each other.

Backup Interface

Set failover interfaces and specify the working mode (electrical or optical interface

mode) for the currently effective failover interfaces.

Click Modify Backup Interface to enter the Backup Interface Configuration page,

and then you can:

• Select one or more interfaces from the Optional Backup Interface(s) list, and

then click the << button to add the selected interfaces to the Backup Interface(s)

list.

• Select one or more interfaces from the Backup Interface(s) list, and then click

the >> button to remove the selected interfaces from the list.

• Modify the working mode of any failover interface in the list at the lower part.

All currently effective failover interfaces are displayed in the list. If no failover

interface is specified, the list is not displayed.

After completing the settings, click Apply to return to the stateful failover

configuration page.
