Allied Telesis AlliedWare Plus GS980MX Series - Example 3; Example 4; Figure 33: Invalid Stack Trunk with Different Numbers of Links; Figure 34: Invalid Stack Trunk with Different Port Types

Chapter 2: Virtual Chassis Stacking

Example 3 Trunks must have the same number of physical links between switches.
Figure 33 is invalid because the top and middle switches are connected
with two links while the top and middle switches are connected to the
bottom switch with only one link each.
Figure 33. Invalid Stack Trunk with Different Numbers of Links
Example 4 Trunks cannot have both 1/2.5/5Gbps and 10Gbps links. Figure 34 shows
an example of an invalid stack trunk because it uses both types of ports.
