Networking device replacement system
A networking device replacement system, includes a second networking device coupled to the configuration server system and the first networking device. The second networking device sends a first peer discovery request to the first networking device that includes second networking device identifying information associated with the second networking device and, in response, receives a first peer discovery response that includes third networking device identifying information associated with a third networking device that the second networking device is replacing. The second networking device sends a first configuration server discovery request to the configuration server system that includes the third networking device identifying information and receives a third networking device configuration file associated with the third networking device. The second networking device configures itself using at least one configuration in the third networking device configuration file.

9. The system of claim 8 , wherein the sending the first networking device identifying information through the port to the fifth networking device is performed in response to determining from the fifth networking device identifying information that the fifth networking device is in a provisioning mode and is the same type of networking device as the first networking device.
10. 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 replacement engine configured to:
