Configuring The Auto Detect Function For Vlan Interface Backup - Huawei Quidway S3900 Series Operation Manual

Operation Manual – Auto Detect
Quidway S3900 Series Ethernet Switches-Release 1510
When the link between the primary VLAN interface and the destination recovers
(that is, the result of the detecting group becomes reachable again), the system
enables the primary VLAN interface and shuts down the secondary VLAN
interface.

2.4.2 Configuration Example
I. Network requirements
Configure a static route between Switch C and Switch A.
Create detecting group 10 on Switch A to detect the connectivity between Switch
B and Switch C.
Configure VLAN 1 interface to be the primary interface, which is enabled when
the result of detecting group 10 is reachable.
Configure VLAN 2 interface to be the secondary interface, which is enabled
when the result of the detecting group is unreachable.
Make sure the routes between Switch A, Switch B, and Switch C are reachable;
and those between Switch A, Switch D, and Switch C are also reachable.
