Uplink failover overview

Uplink failover is a fault tolerance function that changes communication paths in failure of the
LAN switch module or external network device. It is implemented by using together with SFT
(Switch Fault Tolerance), a teaming function of Intel® PROSet, or Linux bonding function on a
server blade.
The following figure shows the uplink failover operation.
