Caution
The example cited here illustrates a loop in a network. Avoid
network loops to prevent broadcast storms.
If the aggregate trunks go to different devices, you can create one
aggregator and let the AT-9400 Series switch form the trunks for you
automatically. This is illustrated in Figure 36. The ports of the two
aggregate trunks on the AT-9400 Series switch are members of the same
aggregator. It is the switch that determines that there are actually two
separate aggregate trunks.

Here is how this example looks in table format.
You could, if you wanted, create separate aggregators for the different
