the first LAG is configured such that the first LAG is represented to components of the system external to the first LAG as a single logical port; and

the second LAG is configured such that the second LAG is represented to components of the system external to the second LAG as a single logical port.

3. The system of claim 1 , wherein the third LAG is configured such that the third LAG is represented to components of the system external to the third LAG as a single logical port.

4. The system of claim 1 , wherein the second hashing algorithm and the third hashing algorithm are identical.

5. The system of claim 1 , wherein the second hashing algorithm and the third hashing algorithm are different.

6. The system of claim 1 , wherein the second LAG comprises a first plurality of physical ports.

7. The system of claim 1 , wherein a fourth LAG and a fifth LAG are designated by the processor as member logical ports of the second LAG.

8. The system of claim 1 , wherein a fourth LAG and a physical port are designated by the processor as member logical ports of the second LAG.

9. An information handling system comprising:

a processor;

a network interface device communicatively coupled to the processor, the network interface device having a plurality of physical ports, wherein a first LAG and a second LAG are designated by the processor as member logical ports of a third LAG;

a memory communicatively coupled to the processor and having stored thereon computer-executable instructions that, when executed by the processor are configured to:

distribute data communicated to the third LAG between the first LAG and the second LAG in accordance with a first hashing algorithm;

distribute data communicated to the third LAG and distributed to the first LAG among the members of the first LAG in accordance with a second hashing algorithm, the second hashing algorithm different from the first hashing algorithm; and

distribute data communicated to the third LAG and distributed to the second LAG among the members of the second LAG in accordance with a third hashing algorithm.

16. The information handling system of claim 9 , wherein a fourth LAG and a physical port are designated by the processor as member logical ports of the second LAG.

17. A method for hierarchical link aggregation, comprising:

receiving a packet of information at an information handling system;

determining that a third link aggregation group (LAG) is a first outgoing logical port of the packet based on a destination address of the packet;

determining that a first LAG or a second LAG is a second outgoing logical port of the packet based on information contained in the packet, wherein the first LAG and the second LAG are member logical ports of the third LAG;

determining that a physical port is a third outgoing logical port of the packet based on information contained in the packet, wherein the physical port is a member port of the first LAG or the second LAG;

transmitting the packet to the physical port;

wherein determining that the first LAG or the second LAG is the second outgoing logical port of the packet includes applying a first hashing algorithm that selects a logical port of the first LAG based on information contained in the packet; and

wherein determining that the physical port is the third outgoing logical port of the packet includes applying a second hashing algorithm that selects a logical port of the first LAG or the second LAG based on information contained in the packet, wherein the first hashing algorithm is different from the second hashing algorithm.
