Configuration Example for Auto Detect Implementation in VLAN Interface Backup

Network requirements
As shown in
between Switch A, Switch D, and Switch C are reachable.
Create detected group 10 on Switch A to detect the connectivity between Switch B and Switch C.
Configure VLAN-interface 1 to be the active interface, which is enabled when the detected group
10 is reachable.
Configure VLAN-interface 2 to be the standby interface, which is enabled when the detected group
10 is unreachable.

Configuration procedure
Configure the IP addresses of all the interfaces as shown in
omitted.
# Enter system view.
<SwitchA> system-view
# Create auto detected group 10.
[SwitchA] detect-group 10
# Add the IP address of 10.1.1.4 to detected group 10 to detect the reachability of the IP address, with
the IP address of 192.168.1.2 as the next hop, and the detecting number set to 1.
