The link failover feature can only be configured on a routable interface. For the link failover
feature to be used on a switched port, another VLAN must be configured (for example,
switch.0002) to logically differentiate the switched port from the default PVID VLAN 1
(switch.0001).
38.3.2. Setting a Link Failover Backup Interface
A backup interface is the interface to which link failover switches when the main interface is determined
to be down. You can add up to three backup interfaces to each link failover configuration.
To set a link failover backup interface:
• In edit mode, navigate to /services/link-failover{link failover ID}/backup and click <Add backup>.
• On the Key settings form, select an interface from the list and click Add.
• On the Backup Settings form, set the backup parameters.
• Commit the changes.
