7.3.6 Example for configuring failover
Networking requirements
As shown in Figure 7-6, to improve network reliability, Link 1 and Link 2 of Switch B are
connected to Switch A and Switch C respectively. Link 1 is the primary link and Link 2 is the
standby link. Link 2 will not be used to forward data until Link 1 is fault.
Switch A and Switch C are connected to the uplink network in link aggregation mode. When
all uplink interfaces of Switch A and Switch C fails, Switch B needs to sense fault in time
switches traffic to the standby link. Therefore, you should deploy failover on Switch A and
Switch C.
Figure 7-6 Configuring failover
Configuration steps
Step 1 Configure failover on Switch A.
Create the failover group.
Alpha-A28E#config
Alpha-A28E(config)#link-state-tracking group 1
Add uplink interfaces to the failover group.
Alpha-A28E(config)#interface port 1
Alpha-A28E(config-port)#link-state-tracking group 1 upstream
