Chapter 2: Virtual Chassis Stacking
Stack of Three Switches
46
In stacks of three or four switches the amount of inter-switch network
traffic might require a stacking trunk with greater bandwidth than that
provided by the default ports 27 and 28. For such situations ports 25 and
26 can also be used as trunk ports. Figure 10 shows examples of stacks of
three and four switches using all four SFP+ ports for the stack trunk..
