Parameters
interface-list: Specifies an interface list, represented by { interface-type interface-num }&<1-2>. The
interface-type and interface-num arguments refer to the type and number of the failover interface, and
the &<1-2> argument indicates that you can specify up to two failover interfaces.
vlan vlan-id: Specifies a backup VLAN by its ID in the range of 1 to 4094.
Usage guidelines
Failover interfaces send and receive stateful failover packets for data backup. Stateful failover packets
are identified by the backup VLAN. Each stateful failover device adds the backup VLAN tag to the
stateful failover packets, and sends the packets through the failover interface. Only the packets that are
received from failover interfaces and carry the backup VLAN tag are treated as stateful failover packets.
Do not configure other services for the backup VLAN. Otherwise, the operation of stateful failover might
be affected.
Examples
# Configure GigabitEthernet 0/1 as a failover interface and VLAN 100 as a backup VLAN.
<Sysname> system-view
[Sysname] dhbk interface gigabitethernet 0/1 vlan 100
display dhbk status
Use display dhbk status to display the stateful failover status information.
