Invalid Stack Trunks
Figure 30 through Figure 33 on page 75 show examples of different types
of invalid stack trunks.
Example 1
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 30 is an example of this
type of invalid trunk
.

Trunks must have a minimum of two ports used per switch. Figure 31 is an
example of an invalid stack trunk with one port used per switch.
