Chapter 6: LACP Port Trunks
84
Section I: Basic Operations
If there will be more than one aggregate trunk on a switch, each trunk
might require a separate aggregator or it might be possible to combine
them into a common aggregator. The determining factor will be whether
the trunks are going to the same device or different devices. If the trunks
are going to the same device, each must have its own aggregator. If they
are going to different devices, the trunks can be members of a common
aggregator. In the latter situation, the switch will differentiate the individual
aggregate trunks.
Here are two examples. Figure 2 illustrates the AT-9400 Switch with two
LACP trunks, each containing three links. Because both aggregate trunks
go to the same 802.3ad-compliant device, in this case another Gigabit
Ethernet switch, each trunk requires a separate aggregator.
