source bandwidth.
In multiple chassis fabrics, each link between chassis contributes 106 or 212
MB of bandwidth between those chassis depending on the speed of the link.
When additional bandwidth is needed between devices, increase the number
of links between the connecting switches. The switch module guarantees
in-order-delivery with any number of links between chassis.

Latency
Latency is a measure of how fast a frame travels from one port to another. The
factors that affect latency include transmission rate and the
source/destination port relationship as shown in
