An information handling system includes a basic input/output system configured to update an attribute of a system-wide firmware downgrade security policy prior to booting to an operating system of the information handling system. The attribute of the system-wide firmware downgrade security policy is used to determine whether to allow or to disallow downgrade of a firmware to a version. A processor may perform the downgrade of the firmware, wherein the downgrade of the firmware includes the processor further configured to check the attribute of the system-wide firmware downgrade security policy and to store a firmware image in a scratchpad. If the attribute of the system-wide firmware downgrade security policy allows the downgrade of the firmware to the version, then the processor may continue with the downgrade of the firmware otherwise discard the firmware image in the scratchpad.

Methods, systems, and devices for managing communications in a distributed system are disclosed. To improve the efficiency of communication, the system may implement the port extension protocol which may allow communication devices to utilize ports of other devices for communication purposes. To do so, the communication devices may instruct the other devices with respect to how the communication devices expect the other devices to process data units transmitted via networks (e.g., network data units). However, not all of the other devices that may process the network data units may include functionality to process and/or implement the instructions from the communication devices. To extend the functionality of such devices, a remote control plane for devices that lack this processing functionality may be provided.

An information handling system may include a management controller and information handling resources that are coupled to the management controller via a first communication channel and a second communication channel, each information handling resource having a first communication channel identifier, and each information handling resource having a second communication channel identifier. The management controller may query the information handling resources via the first communication channel to determine a first set of unique identifiers for the information handling resources; query the information handling resources via the second communication channel to determine a second set of unique identifiers for the information handling resources; and based on a comparison between the first set of unique identifiers and the second set of unique identifiers, create a mapping that correlates the first communication channel identifiers with the second communication channel identifiers.

A method includes determining, during auxiliary power operating mode of an information handling system, devices connected to peripheral component interconnect (PCI) slots and identifying, via a controller of the IHS, when a Virtual Ethernet Bridge (VEB) is present on a first communication path, which indicates that a high power consuming device with sideband enablement is present in a corresponding one of the PCI slots. The method includes configuring, via the first communication path, an uplink port on the VEB, collecting information about the VEB, including a VEB MAC address and capabilities of the VEB, setting a VLAN/MAC filter rule for NC-SI pass-through in the VEB, and configuring an intermediate device within a second communication path between the controller and the VEB for NC-SI pass-through utilizing a management MAC address, enabling NC-SI pass-through of traffic routed between the controller and the VEB.
