• Select Support Asymmetric Path if sessions may enter and leave the
internal network through different devices.
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

Synchronization
Specify the local device as the active device during configuration
synchronization.
If the check box is not selected, the local device serves as the standby device
during configuration synchronization.
Auto Synchronization
Select this check box to enable auto synchronization.
• If you select the check box, the active device will synchronize all configurations
to the standby device at a time, and automatically synchronize configuration
updates to the standby device.
• If you do not select the check box, you can only click Manual
Synchronization to manually synchronize all configurations.
IMPORTANT:
You are recommended to enable auto synchronization.
Manual Synchronization
Click the Manual Synchronization button to synchronize all configurations
from the active device to the standby device.
If the current stateful failover state is synchronization, you can select the manual
synchronization method.
