1. Getting started
This chapter provides process flow information to configure and provision services. It also provides an overview of the document organization and content, and describes the terminology used in this guide.
1.1. About this guide
| 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. |
This guide describes the subscriber services support provided by 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.
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 as described in this document” is used to indicate that the topic and CLI commands apply to the following 7210 SAS platforms implicitly operating in the specified modes. See Table 1 for more information. network mode of operation 7210 SAS-R6 and 7210 SAS-R12
standalone mode of operation 7210 SAS-R6 and 7210 SAS-R12

1.1.1. Document structure and content
This guide uses the following structure to describe routing protocols and route policies 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. |
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.
Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.
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.
access-uplink
In the access-uplink operating mode, the 7210 SAS router uplinks to the network using Layer 2 Ethernet VLAN switching (without IP/MPLS).
Platforms Supported: 7210 SAS-D, 7210 SAS-Dxp, 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, 7210 SAS-K 3SFP+ 8C, and 7210 SAS-T
network
In the network operating mode, the 7210 SAS router uses IP/MPLS uplinks to the network. The IP routing protocols and MPLS functionality is available; refer to the appropriate 7210 SAS software user guide for more information about supported features.
Platforms Supported: 7210 SAS-K 2F6C4T, 7210 SAS-K 3SFP+ 8C, 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, 7210 SAS-Sx/S 1/10GE, 7210 SAS-Sx 10/100GE, and 7210 SAS-T
satellite
In the satellite operating mode, the 7210 SAS platform uses high-capacity uplinks (for example, 10GE ports on the 7210 SAS-Mxp and 100GE ports on the 7210 SAS-Sx 10/100GE) to connect to the 7750 SR host. The 7210 SAS router is managed by the 7750 SR host. There is no direct CLI access to the satellite node, and all services and protocols are configured on the host.
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.
Platforms Supported: 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE
standalone
In the standalone operating mode, the 7210 SAS platform supports IP/MPLS uplinks. It is operated and managed independently.
The functionality and features available on the standalone 7210 SAS platform are similar to the
network operating mode. The standalone mode is primarily used to differentiate between a node being managed by the 7750 SR host (in the
satellite operating mode), and a node managed independently (standalone operating mode).
Platforms Supported: 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE
standalone-VC
In the standalone-VC operating mode, a set of 7210 SAS devices are stacked to provide larger 1GE/10GE port density and control-plane redundancy. The stack of nodes is provisioned and managed as a single chassis, and not as individual nodes.
The functionality and features available on the 7210 SAS platform are similar to the
network operating mode, with additional capabilities, such as control-plane redundancy with non-stop routing and non-stop services.
Platforms Supported: 7210 SAS-Sx/S 1/10GE
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 that 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.

Notes:
Supports MPLS uplinks only and implicitly operates in network mode
By default, the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C boot up in the
network mode of operation. These platforms also allow the use of
access-uplink port mode (without explicit BOF configuration), which provides the option to use Layer 2 uplinks instead of IP/MPLS uplinks to the network core, similar to the 7210 SAS-K 2F1C2T router.
See section
1.3 for information about port mode configuration
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.
access port mode
Access ports are configured for customer-facing traffic if Service Access Points (SAPs) are required. The appropriate encapsulation type must be configured to distinguish the services on the port; services are configured on the port based on the encapsulation value.
Access ports can be configured on all the 7210 SAS platforms.
access-uplink port mode
Access-uplink ports provide native Ethernet connectivity in service provider transport or in an infrastructure network. With this option, the encap-type can be configured to only QinQ. Access-uplink SAPs, which are QinQ SAPs, can only be configured on an access-uplink port to allow the operator to differentiate multiple services being carried over a single uplink port.
This is the default port mode of a 7210 SAS node in the
access-uplink mode of operation.
network port mode
Network ports are configured for network-facing traffic in the service provider transport or infrastructure network, and provide IP/MPLS uplinks.
This is the default port mode of a 7210 SAS node in the
network or
standalone mode of operation.
hybrid port mode
Hybrid ports are configured for access and network facing traffic, and allow a single port to operate in both access and network 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.
Table 2:
