Abstract

An integrated network and management controller and method for operating are disclosed. The network and management controller includes a network processing component that performs network-based functions and filters management data received over a network intended for consumption by the network and management controller. The network and management controller also includes a microcontroller that performs network based functions in conjunction with the network processing component and performs management functions associated with the computer system. The network processing component and the microcontroller are embedded in the network and management controller and are logically connected.
