CHAPTER 22
Basic Redundancy
BLADEOS 6.5 includes various features for providing basic link or device redundancy:

Trunking for Link Redundancy
Multiple switch ports can be combined together to form robust, high-bandwidth trunks to other
devices. Since trunks are comprised of multiple physical links, the trunk group is inherently fault
tolerant. As long as one connection between the switches is available, the trunk remains active.
In Figure 39, four ports are trunked together between the switch and the enterprise routing device.
Connectivity is maintained as long as one of the links remain active. The links to the server are also
trunked, allowing the secondary NIC to take over in the event that the primary NIC link fails.
