Stateful Failover Configuration Example
Network requirements
In Figure 2 , Device A and Device B are deployed for stateful failover in an enterprise network to provide
Internet access. They both run NAT to provide IP address translation.
It is required to:
• Configure the devices to back up each other, so that when one device fails, the other device takes
over the services to ensure service continuity.
• Enable automatic configuration synchronization from Device A (active device) to Device B (standby
device).
Configuration procedure
Step1 Configure Device A.
# Configure stateful failover.
• Select high reliability > Stateful Failover from the navigation tree.
• Click Modify Backup Interface to enter the Backup Interface Configuration page as
shown in
Figure 5 . Select GigabitEthernet0/1 from the Optional Backup Interface(s) list,
click the << button, and then click Apply.

Then enter the Stateful Failover Configuration page as shown in
Figure 6 and complete the
following settings:
• Select the Enable Stateful Failover check box.
• Select Unsupport Asymmetric Path for Backup Type.
• Select the Main Device for Configuration Synchronization check box.
• Select the Auto Synchronization check box.
• Click Apply.
