Automated link aggregation group configuration system
An automated Link Aggregation Group (LAG) configuration system includes a plurality of slave switch devices that are each coupled to an endhost device by at least one respective link. Each of the plurality of slave switch devices receives a Link Aggregation Group (LAG) communication from the endhost device, and forwards endhost device information in that LAG communication to a master switch device. The master switch device receives endhost device information from each of the plurality of slave switch devices and determines that each of the plurality of slave switch devices are coupled to the endhost device. In response, the master switch device sends a LAG instruction to each of the plurality of slave switch devices that causes the at least one respective link that couples each of the plurality of slave switch devices to the endhost device to be configured in a LAG.

6. The system of claim 1 , wherein the master switch device is configured to:
determine a common Media Access Control (MAC) address; and
provide the common MAC address to each of the plurality of slave switch devices in the LAG instruction in order to cause each of the plurality of slave switch devices to communicate with the endhost device via the LAG using the common MAC address.
7. The system of claim 1 , wherein at least one link coupled the master switch device to the endhost device, wherein the master switch device is configured to:
configure the at least one link that couples the master switch device to the endhost device as part of the LAG.
8. An Information Handling System (IHS), comprising:
a processing system; and
a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide an auto-Link Aggregation Group (LAG) configuration engine that is configured to:
receive, from each of a plurality of slave switch devices and in response to the plurality of slave switch devices electing the auto-LAG configuration engine to perform management operations on any of the plurality of slave switch device, endhost device information received in respective LAG communications that were each generated and transmitted by an endhost device that is coupled to each of the plurality of slave switch devices via at least one respective link;
determine, based on the endhost device information, that each of the plurality of slave switch devices are coupled to the endhost device; and
send, to each of the plurality of slave switch devices, a LAG instruction that causes the at least one respective link that couples each of the plurality of slave switch devices to the endhost device to be configured in a LAG.
9. The IHS of claim 8 , wherein the LAG communications are Link Aggregation Control Protocol (LACP) communications.
10. The IHS of claim 8 , wherein the LAG configuration engine is configured to:
determine that each of the plurality of slave switch devices are coupled to the endhost device based on the endhost device information that includes an address of the endhost device.
11. The IHS of claim 8 , wherein the LAG configuration engine is configured to:
send, to each of the plurality of slave switch devices, a LAG removal instruction that causes the at least one respective link that couples each of the plurality of slave switch devices to the endhost device to be removed from the LAG.
12. The IHS of claim 8 , wherein the LAG configuration engine is configured to:
determine a common Media Access Control (MAC) address; and
provide, to each of the plurality of slave switch devices, the common MAC address in the LAG instruction in order to cause each of the plurality of slave switch devices to communicate with the endhost device via the LAG using the common MAC address.
13. The IHS of claim 8 , further comprising:
at least one port that is coupled to the processing system and to at least one link to the endhost device, wherein the LAG configuration engine is configured to:
configure the at least one link that is coupled to the at least one port as part of the LAG.
14. A method for automatically configuring a Link Aggregation Group (LAG), comprising:
receiving, by a master switch device from each of a plurality of slave switch devices that elected the master switch device to perform management operations on any of the plurality of slave switch devices, endhost device information received in respective LAG communications that were each generated and transmitted by an endhost device that is coupled to each of the plurality of slave switch devices via at least one respective link;
determining, by the master switch device based on the endhost device information, that each of the plurality of slave switch devices are coupled to the endhost device; and
sending, by the master switch device to each of the plurality of slave switch devices, a LAG instruction that causes the at least one respective link that couples each of the plurality of slave switch devices to the endhost device to be configured in a LAG.
15. The method of claim 14 , further comprising:
determining, by the master switch device, that the endhost device is associated with an endhost device profile that provides for automatic configuration of the endhost device.
16. The method of claim 14 , wherein the LAG communications are Link Aggregation Control Protocol (LACP) communications.
