Initial release of this document.
The Cisco IOS XR Supported Platforms and Features document describes various hardware and software components that compose the Cisco IOS XR system.
This document is intended for users who design integrated routing systems that use Cisco IOS XR software.
The Cisco IOS XR software is a distributed operating system designed for continuous system operation combined with service flexibility and speed.
The following is a high-level overview of Cisco IOS XR software features and benefits:
•IP and Routing—Supports a wide range of IPv4 and IPv6 services, and routing protocols; including Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, and Routing Policy Language (RPL).
•Partitioning into Logical Router (LR)—A logical router is a set of line cards and route processors (RPs) that form a complete router. More specifically, each LR contains its own instance of dynamic routing, IP stack, SysDB (system database), interface manager, event notification system, and so on.
•MPLS—Supports Multiprotocol Label Switching (MPLS) protocols such as Traffic Engineering (TE), Resource Reservation Protocol (RSVP), and Label Distribution Protocol (LDP). Layer 3 Virtual Private Networks (L3VPN) supports multiple simultaneous Layer 3 VPN routing and forwarding (VRF) instances.
•Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Bidirectional Protocol Independent Multicast (BIDIR-PIM) support (on the Cisco CRS-1 Series router).
•Quality of service (QoS)—Supports rich QoS mechanisms including classifying, policing, marking, queuing, and shaping. The operating system supports the Modular QoS CLI (MQC), a consistent API that is used to configure QoS features on Cisco routing platforms.
•Manageability—Provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces.
•Security—Provides comprehensive network security features including access control lists (ACLs), routing authentications, AAA/TACACS+, Secure Shell (SSH), SNMPv3, and leading Routing Policy Language (RPL) support. Control plane protections integrated into line card ASICs include Generalized TTL Security Mechanism (GTSM), RFC 3682, and dynamic control plane protection.
•The Craft Works Interface (CWI)— A client-side application used to configure and manage Cisco routers. The management and configuration features include fault, configuration, security, and inventory, with an emphasis on speed and efficiency. The CWI provides a context-sensitive graphical representation of the objects in a Cisco router, simplifying the process of configuring and managing the router. The CWI allows you to log in to multiple routers and perform management tasks.
•Availability—Supports rich availability features such as Hot Standby Router Protocol (HSRP)/Virtual Router Redundancy Protocol (VRRP), fault containment, fault tolerance, fast switchover, link aggregation, and nonstop forwarding (NSF).
•In Service Software Upgrade (ISSU)—Supports a modular-packaging-based release model to minimize impact of upgrades, and supports ISSU with NSF where possible.

Table 2 lists the platforms supported by Cisco IOS XR software and in which release the platform was first supported.
Cisco CRS-1 Router
The Cisco CRS-1 is a highly scalable routing platform designed for efficient service provider point-of-presence (POP) evolution as the IP network grows into a multiservices network.
The main features of all Cisco CRS-1 routing systems include:
•A highly scalable service provider router with a capacity of 640 gigabits per second (Gbps) for a CRS-1 8-Slot Line Card Chassis (LCC) and 1.2 terabits per second (Tbps) for a CRS-1 16-Slot LCC of bandwidth. The Cisco CRS-1 is scalable to 92 Tbps capacity.
•Supports expansion from single-chassis to multishelf systems.
•A wide range of interface speeds and types (for example, OC-48 Packet-over-SONET/SDH (POS) and OC-192 POS), and a programmable MSC forwarding engine that provides full-featured forwarding at line-rate speeds.
•Redundancy and reliability features allow nonstop operation even during service upgrades of equipment, with no single points of failure in hardware or software.
The Cisco CRS-1 8-Slot LCC uses the same line cards, the same software, and the same type of midplane and switch mechanism as the Cisco CRS-1 16-Slot LCC. It provides the higher-speed interfaces found in the Cisco CRS-1 16-Slot LCC, but in a smaller platform, allowing easier deployment in locations where power, cooling, and other facilities might be hard to provision.

The routing system is built around a scalable, distributed three-stage Benes switch fabric and a variety of data interfaces. The data interfaces are contained on physical layer interface modules (PLIMs) and SMDS interface protocol that mate with an associated MSC through the chassis midplane. The switch fabric cross-connects MSCs to each other.
Cisco CRS-1 8-Slot Line Card Chassis (LCC)
The Cisco CRS-1 8-Slot LCC has eight MSC slots, each with a capacity of 40 Gbps, for a total routing capacity for each chassis of 640 Gbps. The routing system is built around a scalable, distributed three-stage Benes switch fabric and a variety of data interfaces. The data interfaces are contained on PLIMs and SIPs that mate with an associated MSC through the chassis midplane. The switch fabric cross-connects MSCs to each other

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
