Figure 11-3 Principles of interface backup
As shown in Figure 11-3, GE 1/1/1 and GE 1/1/2 on Switch A are connected to their uplink
devices respectively. The interface forwarding states are shown as below:
Under normal conditions, GE 1/1/1 is the primary interface while GE 1/1/2 is the backup
interface. GE 1/1/1 and the uplink device forward packet while GE 1/1/2 and the uplink
device do not forward packets.
When the link between GE 1/1/1 and its uplink device fails, the backup GE 1/1/2 and its
uplink device forward packets.
When GE 1/1/1 restores normally and keeps Up for a period (restore-delay), GE 1/1/1
restores to forward packets and GE 1/1/2 restores standby status.
When a switching between the primary interface and the backup interface occurs, the switch
sends a Trap to the NView NNM system.
Application of interface backup in different VLANs
By applying interface backup to different VLANs, you can enable two interfaces to share
service load in different VLANs, as shown in Figure 11-4.
