This deployment guide will provide a step-by-step configuration in the data center utilizing the FN I/O
Module, the PowerEdge FN410S. In this deployment guide, the two FN410S's installed in the rear of
the FX2 chassis are configured as a virtual link trunk (VLT) pair of switches. This provides the
functionality for the pair of switches to perform as one logical switch
What is VLT?
VLT allows physical links between two switching devices to appear as a single virtual link to other
networking devices. VLT reduces the role of spanning tree protocols (STPs) by allowing link
aggregation group (LAG) terminations on two separate distribution or core switches, and by supporting
a loop-free topology. VLT provides Layer 2 multipathing, creating redundancy through increased
bandwidth, enabling multiple parallel paths between nodes and load-balancing traffic where alternative
paths exist.
