Overview
Link aggregation aggregates multiple physical Ethernet ports into one logical link, also called an
aggregation group.
It allows you to increase bandwidth by distributing traffic across the member ports in the aggregation
group. In addition, it provides reliable connectivity because these member ports can dynamically back
up each other.

Basic Concepts of Link Aggregation

Aggregate interface
An aggregate interface is a logical Layer 2 or Layer-3 aggregate interface.
Aggregation group
An aggregation group is a collection of Ethernet interfaces. When you create an aggregate interface,
an aggregation group numbered the same is created automatically depending on the type of the
aggregate interface:
If the aggregate interface is a Layer 2 interface, a Layer 2 aggregation group is created. You can
assign only Layer 2 Ethernet interfaces to the group.
If the aggregate interface is a Layer-3 interface, a Layer-3 aggregation group is created. You can
assign only Layer-3 Ethernet interfaces to the group.
The current device only supports Layer 2 aggregation groups.
States of the member ports in an aggregation group
A member port in an aggregation group can be in one of the following two states:
