Switching fabric loop prevention system

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 a switching fabric loop prevention engine that is configured to:
• receive, from a directly connected device, directly connected device identification information;
• automatically determine, based on the directly connected device identification information received from the directly connected device, a first slave switch device role for the IHS;
• receive, from a master switch device, a first loop prevention configuration that configures the switching fabric loop prevention engine to prevent first type communications that have been received from one of a plurality of second slave switch devices having a second slave switch device role from being forwarded to another of the plurality of second slave switch devices having the second slave switch device role;
• receive, from one of the plurality of second slave switch devices having a second slave switch device role, a first type communication;
• and
• prevent the first type communication from being forwarded to another of the plurality of second slave switch devices having the second slave switch device role.

A method for preventing loops in a switching fabric, comprising:

• receiving, by a first slave switch device from a directly connected device, directly connected device identification information;
• automatically determining, by the first slave switch device based on the directly connected device identification information received from the directly connected device, a first slave switch device role for the first slave switch device;
• receiving, by the first slave switch device from a master switch device, a first loop prevention configuration that configures the first slave switch device to prevent first type communications that have been received from one of a plurality of second slave switch devices having a second slave switch device role from being forwarded to another of the plurality of second slave switch devices having the second slave switch device role;
• receiving, by the first slave switch device from one of the plurality of second slave switch devices having a second slave switch device role, a first type communication;
• and
• preventing, by the first slave switch device, the first type communication from being forwarded to another of the plurality of second slave switch devices having the second slave switch device role.
