Invalid Stack Trunks

Example 1

Example 2

62
Figure 19 through Figure 22 on page 63 show examples 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 19 is an example of this
type of invalid trunk
.
Figure 19. Invalid Stack Trunk with an Intermediary Networking Device
Trunks must have a minimum of two ports used per switch. Figure 20 is an
example of an invalid stack trunk that has only one port per switch.
