command to cancel FS. Then, the
principles of selecting the current link
according to link status are as below:
If the Up/Down status of the two
interfaces is the same, the primary
interface is of high priority.
If the Up/Down status of the two
interfaces is different, the Up interface
is of high priority.

11.2.7 Example for configuring interface backup
Networking requirements
As shown in Figure 11-5, the PC accesses the server through the Switch. To implement a
reliable remote access from the PC to the server, configure an interface backup group on
Switch A and specify the VLAN list so that the two interfaces concurrently forward services
in different VLANs and balance load. Configure Switch A as below:
Add GE 1/1/1 to VLANs 100–150 as the primary interface and GE 1/1/2 as the backup
interface.
Add GE 1/1/2 to VLANs 151–200 as the primary interface and GE 1/1/1 as the backup
interface.
When GE 1/1/1 or its link fails, the system switches traffic to the backup interface GE 1/1/2 to
resume the link.
Switch A is required to support interface backup while other switches are not.
