1.1. About this guide

This guide describes system concepts and provides configuration examples to provision cards, MDAs, and ports on the following 7210 SAS platforms, operating in one of the modes described in Table 1. If multiple modes of operation apply, they are explicitly noted in the topic.

Note: Unless explicitly noted otherwise, this guide uses 7210 SAS-Dxp to refer to the 7210 SAS-Dxp 12p, 7210 SAS-Dxp 16p, and 7210 SAS-Dxp 24p platforms.

See section 1.2 for information about the modes of operation supported by the 7210 SAS product family.

Note: Unless explicitly noted otherwise, the phrase “Supported on all 7210 SAS platforms described in this document” is used to indicate that the topic and CLI commands apply to all the 7210 SAS platforms in the following list, when operating in the specified modes only. access-uplink mode of operation 7210 SAS-D, 7210 SAS-Dxp, 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C network mode of operation 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C When configured in the access-uplink or network mode of operation, the 7210 SAS platform implicitly operates in the standalone mode.

1.1.1. Document structure and content

This guide uses the following structure to describe card and port configuration content.

Note: This guide generically covers Release 22.x.Rx content and may include some content that will be released in later maintenance loads. Refer to the 7210 SAS Software Release Notes 22.x.Rx, part number 3HE 18217 000x TQZZA, for information about features supported in each load of the Release 22.x.Rx software.

1. This guide is organized into functional chapters and provides concepts and descriptions of the implementation flow. Each chapter describes a software area and provides CLI syntax and command usage to configure parameters for the functional area.
2. Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.
3. Refer to the 7210 SAS-Mxp, R6, R12, S, Sx, T Basic System Configuration Guide for boot options to configure the satellite mode of operation on the router. Refer to the 7750 SR software user guides for information about service and protocol provisioning, and operating the 7210 SAS router in satellite mode.
4. Unless explicitly noted, the CLI commands and their configuration is similar for both network and access-uplink operating modes for features applicable to both modes of operation.

1.2. 7210 SAS modes of operation

Unless explicitly noted, the phrase “mode of operation” and “operating mode” refers to the current operating mode of the 7210 SAS router. Each operating mode provides configuration access to a specific group of CLI commands.

Note: Not all CLI commands are supported on all 7210 SAS platforms in all modes of operation. Users can only configure CLI commands supported by the current operating mode of the router. Refer to the 7210 SAS Software Release Notes 22.x.Rx, part number 3HE 18217 000x TQZZA, and to the appropriate 7210 SAS software user guide for information about features and capabilities supported by a 7210 SAS platform when operating in a specific mode.

The following modes of operation are supported by the 7210 SAS product family.

For 7210 SAS platforms that support multiple explicit modes of operation (Table 1), the operating mode must be configured in the Boot Option File (BOF) to ensure the router boots up in the specified mode. For example, the 7210 SAS-T supports access-uplink and network modes of operation, and the 7210 SAS-Sx/S 1/10GE supports satellite, standalone, and standalone-VC mode of operations. In some cases, the 7210 SAS router operates in a specific mode implicitly, and explicit configuration is not required.

Refer to the appropriate Basic System Configuration Guide for boot options and information about how to boot the 7210 SAS platform in a specific operating mode.

The following table lists the supported modes of operation and the configuration methods for the 7210 SAS platforms. Unless explicitly noted otherwise, the operating mode is supported on all variants of the specific 7210 SAS platform.

1.3. 7210 SAS Port Modes

Unless explicitly noted, the phrase “port mode” refers to the current port configuration of the 7210 SAS node. The 7210 SAS platform supports the configuration of the following port modes.

Port modes available for configuration on a 7210 SAS node are determined by the current mode of operation of the router.

Note: The 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C are unique; all port modes listed in Table 2 are available for configuration on the router, regardless of the current mode of operation.

The following table lists the port mode configuration support per 7210 SAS mode of operation.

The following table lists the port mode configuration supported by the 7210 SAS product family. Refer to the appropriate Interface Configuration Guide for detailed information about configuring the port modes for a specific platform.

1.4. Interface configuration process

The following table describes the tasks necessary to configure cards and ports.

This guide is presented in an overall logical configuration flow. Each section describes a software area and provides CLI syntax and command usage to configure parameters for a functional area.
