1. Getting Started

1.1. About This Guide

This guide describes system concepts and provides configuration examples to provision Input/Output modules (IOMs), XMA Control Modules (XCMs), also referred to as cards, Media Dependent Adapters (MDAs), XRS Media Adapters (XMAs), and ports.

This guide is organized into functional chapters and provides concepts and descriptions of the implementation flow, as well as Command Line Interface (CLI) syntax and command usage.

The topics and commands described in this document apply to the:

  1. 7450 ESS
  2. 7750 SR
  3. 7950 XRS
  4. VSR

Table 1 lists the available chassis types for each SR OS router.

  1. 7450 ESS-7/12 running in standard mode (not mixed-mode)
  1. 7450 ESS-7/12 running in mixed-mode (not standard mode)
  2. 7750 SR-a4/a8
  3. 7750 SR-c4/c12
  4. 7750 SR-1e/2e/3e
  5. 7750 SR-7/12
  6. 7750 SR-12e
  7. 7750 SR-7s/14s
  8. 7750 SR-1
  1. 7950 XRS-16c
  2. 7950 XRS-20/40

For a list of unsupported features by platform and chassis, refer to the SR OS 16.0.Rx Software Release Notes, part number 3HE 14220 000x TQZZA or the VSR Release Notes, part number 3HE 14204 000x TQZZA.

Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.

Note:

This guide generically covers Release 16.0.Rx content and may contain some content that will be released in later maintenance loads. Refer to the SR OS 16.0.Rx Software Release Notes, part number 3HE 14220 000x TQZZA or the VSR Release Notes, part number 3HE 14204 000x TQZZA, for information about features supported in each load of the Release 16.0.Rx software.

1.2. Interface Configuration Process

Table 2 lists the tasks necessary to configure IOMs and XCMs (also referred to as cards), MDAs and XMAs, and ports.

Note:

For consistency across platforms, XMAs are modeled in the SR OS (CLI and SNMP) as MDAs.

Unless specified otherwise:

  1. the term “card” is used generically to refer to both IOMs and XCMs
  2. the term “MDA” is used generically to refer to both MDAs and XMAs
