Abstract
Mechanisms to enable management controllers to learn the control plane hierarchy in data center environments. The data center is configured in a physical hierarchy including multiple pods, racks, trays, and sleds and associated switches. Management controllers at various levels in a control plane hierarchy and associated with switches in the physical hierarchy are configured to add their IP addresses to DHCP (Dynamic Host Control Protocol) responses that are generated by a DCHP server in response to DCHP requests for IP address requests initiated by DHCP clients including manageability controllers, compute nodes and storage nodes in the data center. As the DCHP response traverses each of multiple switches along a forwarding path from the DCHP server to the DHCP client, an IP address of the manageability controller associated with the switch is inserted. Upon receipt at the DHCP client, the inserted IP addresses are extracted and used to automate learning of the control plane hierarchy.
