Bandwidth
Bandwidth is a measure of the volume of data that can be transmitted at a given
transmission rate. A 1Gbps/2Gbps port can transmit or receive at 1 Gbps or 2
Gbps depending on the device to which it is connected. 10 Gbps ports transmit at
10 Gbps. The switch supports all transmission rate combinations as shown in
Table 3-2.
In multiple chassis fabrics, each link between chassis contributes 100, 200, or
1000 megabytes 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 guarantees
in-order-delivery with any number of links between chassis.
