As mentioned earlier, a 10Gbps trunk can have either fiber optic
transceivers or AT-SP10TW direct attach twinax cables. However,
a trunk cannot have both types of cables. An example of this type
of invalid trunk is shown in Figure 22.

 The links of a stack trunk must all be the same speed. Thus, a
stack trunk cannot have both 10Gbps links and 40Gbps or
100Gbps links. Figure 23 is an example of an invalid trunk with
links of different speeds.
