Chapter 2: Virtual Chassis Stacking

Table 10 lists the maximum number of trunk ports that a switch can
support at one time. The number varies by line card. For example,
a switch can have a maximum of eight trunk ports when a trunk is
build with ports on AT-XEM2-12XS Line Cards.
Figure 13 is an example of a trunk the exceeds the permitted
number of ports per switch. The trunk uses AT-XEM2-4QS Line
Cards, which, as listed in Table 10, can have a maximum of four
trunk ports per switch. The two switches have six stacking ports
each, making the trunk invalid. To bring the example into
compliance with the rule, you would have to remove two trunk
ports from each switch.
