Invalid Stack Trunks

Example 1

Example 2

Figure 31 through Figure 34 on page 78 show examples of different types
of invalid stack trunks.
Stack trunks must be direct links between trunk ports. There cannot be
any intermediary networking devices, such as media converters, Ethernet
switches, or routers, between trunk ports. Figure 31 is an example of this
type of invalid trunk
.
