Aggregation group, member port, and aggregate interface

Link bundling is implemented through interface bundling. An aggregation group is a group of Ethernet interfaces bundled together, which are called member ports of the aggregation group. For each aggregation group, a logical interface (called an aggregate interface), is created.

When you create an aggregate interface, the device automatically creates an aggregation group of the same type and number as the aggregate interface. For example, when you create aggregate interface 1, aggregation group 1 is created.

You can assign Layer 2 Ethernet interfaces only to a Layer 2 aggregation group.

The port rate of an aggregate interface equals the total rate of its Selected member ports. Its duplex mode is the same as that of the Selected member ports. For more information about the states of member ports in an aggregation group, see "Aggregation states of member ports in an aggregation group."
