Aggregation group, member port, and aggregate interface

An aggregation group is a collection of physical interfaces that are bundled together for the purpose of load distribution and redundancy. These physical interfaces are called member ports. They are configured through a logical aggregate interface.

An aggregate interface can be one of the following types:

  • Layer 2: The member ports of the corresponding Link Aggregation Group can only be Layer 2 Ethernet interfaces.

  • Layer 3: The member ports of the corresponding Link Aggregation Group can only be Layer 3 interfaces.

The effective port rate of an aggregate interface equals the total rate of its member ports. Only full duplex mode members are eligible for aggregation.
