Trunk Groups

Each set of connections between two ELS100-16TXs is called a
Trunk Group. You can create up to eight trunk groups, each with up
to eight ports, to interconnect your ELS100-16TXs.
For example, if you have three ELS100-16TXs (A, B, and C), as
shown in Figure 3-2, you could connect them using a single
Ethernet segment. However, that would limit the interconnection
to 100 Mbps. To solve this problem, you could connect A to B with
one Trunk Group, and connect B to C with a second Trunk Group.
