信息技术 网络控制器边带接口（NC-SI）规范集

[中文适用范围]： 本文档定义了负责将网络控制器连接到管理控制器的边带接口的功能和行为。它还概述了从网络控制器发往管理控制器的网络流量的行为模型。本文档定义了网络控制器边带接口 (NC‑SI) 的以下两个方面：接口的行为，包括其运行状态以及相关组件的状态、通过接口支持的通信协议的有效载荷和命令。本文档的范围仅限于解决与一个或多个网络控制器通信的单个管理控制器。本文档还定义了基于 3.3V RMII 的传输 (RBT) 的物理介质的以下方面：RBT 上的 NC-SI 的传输绑定、RBT 的电气和时序要求、RBT 的可选硬件仲裁机制。本文档仅讨论可能影响网络控制器或管理控制器行为的主题，因为它与边带接口操作有关。 NC-SI over MCTP 绑定规范 (DSP0261) 本文档定义了 NC-SI 协议元素和 MCTP 元素之间的绑定，以便使用 MCTP 传输 NC-SI 控制和直通流量。本文档的部分内容依赖于其他规范中的信息和定义，第 2 条 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000D0000005F00520065006600390039003100390030003600350030000000 标识了这些信息和定义。其中两个参考资料特别相关：DMTF DSP0222，网络控制器边带接口 (NC-SI) 规范，提供了本规范通过 MCTP 绑定的 NC‑SI 基本控制。 DMTF DSP0236，管理组件传输协议（MCTP）基础规范，定义了传输 NC-SI 控制和直通数据包的 MCTP 传输。 [外文原描述]： This document defines the functionality and behavior of the Sideband Interface responsible for connecting the Network Controller to the Management Controller. It also outlines the behavioral model of the network traffic destined for the Management Controller from the Network Controller. This document defines the following two aspects of the Network Controller Sideband Interface (NC‑SI): behavior of the interface, which include its operational states as well as the states of the associated components, the payloads and commands of the communication protocol supported over the interface. The scope of this document is limited to addressing only a single Management Controller communicating with one or more Network Controllers. This document also defines the following aspects of a 3.3V RMII Based Transport (RBT) based physical medium: transport binding for NC-SI over RBT, electrical and timing requirements for the RBT, an optional hardware arbitration mechanism for RBT. Only the topics that may affect the behavior of the Network Controller or Management Controller, as it pertains to the Sideband Interface operations, are discussed in this document. NC-SI over MCTP Binding Specification (DSP0261) This document defines the bindings between NC-SI protocol elements and MCTP elements in order for NC-SI Control and Pass-Through traffic to be transported using MCTP. Portions of this document rely on information and definitions from other specifications, which clause 2 identifies. Two of these references are particularly relevant: DMTF DSP0222 , Network Controller Sideband Interface (NC-SI) Specification, provides the NC‑SI base control that is to be bound over MCTP by this specification. DMTF DSP0236 , Management Component Transport Protocol (MCTP) Base Specification, defines the MCTP transport on which the NC-SI Control and Pass-through packets are to be conveyed.
