Intel® Server Board S2600CP and Intel® Server System P4000CP Platform Management Intel® Server Board S2600CP and Server System P4000CP TPS 12 RAKP-HMAC-MD5 MD5-128 AES-CBC-128 Note: Cipher suite 0 defaults to callback privilege for security purposes. This may be changed by any administrator. For user authentication, the BMC can be configured with 'null' user names, whereby password/key lookup is done based on 'privilege level only', or with non-null user names, where the key lookup for the session is determined by user name. IPMI 2.0 messaging introduces payload types and payload IDs to allow data types other than IPMI commands to be transferred. IPMI 2.0 serial-over-LAN is implemented as a payload type. Table 23.

This is implemented per the Intelligent Platform Management Interface Specification Second Generation, Version 2.0. 6.4.3.4 BMC LAN Channels The BMC supports three RMII/RGMII ports that can be used for communicating with Ethernet devices. Two ports are used for communication with the on-board NICs and one is used for communication with an Ethernet PHY located on an optional add-in card (or equivalent on-board circuitry). 6.4.3.4.1 Baseboard NICs The specific Ethernet controller (NIC) used on a server is platform-specific but all baseboard device options provide support for an NC-SI manageability interface. This provides a sideband high-speed connection for manageability traffic to the BMC while still allowing for a simultaneous host access to the OS if desired. The Network Controller Sideband Interface (NC-SI) is a DMTF industry standard protocol for the side band management LAN interface. This protocol provides a fast multi-drop interface for management traffic. The baseboard NIC(s) are connected to a single BMC RMII/RGMII port that is configured for RMII operation. The NC-SI protocol is used for this connection and provides a 100 Mb/s fullduplex multi-drop interface which allows multiple NICs to be connected to the BMC. The physical layer is based upon RMII, however RMII is a point-to-point bus whereas NC-SI allows 1 master and up to 4 slaves. The logical layer (configuration commands) is incompatible with RMII. Multi-port baseboard NICs on some products will provide support for a dedicated management channel than can be configured to be hidden from the host and only used by the BMC. This mode of operation is configured by a BIOS setup option. 74 Revision 1.2 Intel order number G26942-003
