Note For the latest information on which cards are supported by the Cisco IOS XR software in Cisco XR 12000 Series Routers and Cisco 12000 Series Internal Routers, see Release Notes for Command Cisco IOS XR Software Release 4.0.
Page 14: Cisco Xr 12000 Series Router Overview
Cisco XR 12000 Series Router Overview Cisco XR 12000 Series Router Overview The Cisco XR 12000 Series Router is powered by Cisco IOS XR software, allowing service providers to isolate public and private services through the virtualization of a single router into separate physical and logical partitions.
Page 15 This feature supports the Cisco IOS XR Software goal of continuous system availability and allows for quick recovery from process or protocol failures with minimal disruption to customers or traffic.

Throughout this guide, the term PRP is used to refer to the PRP cards supported on Cisco XR 12000 Series Routers. Cisco XR 12000 Series Routers, support both the PRP-2 and the PRP-3 cards. If a feature or an issue applies to only one platform, the accompanying text specifies the platform.
Page 22: Connecting To The Router Through The Console Port
Connecting to the Router Through the Console Port The first time you connect to a new router with Cisco IOS XR software, you must connect through the Console port on the DSC. Although typical router configuration and management take place using an Ethernet port on the DSC, you must configure the console port for your LAN before it can be used.

Page 49: Cli Prompt
Configuration Guide for the Cisco XR 12000 Series Router. CLI Prompt After you log in, you see the CLI prompt for the Cisco IOS XR software. This prompt identifies the router or SDR to which you are issuing commands. The CLI prompt represents the path, through the router, to the CPU that executes the commands you enter.
Page 50: User Access Privileges
Slot in which the RP or DRP is installed. In a Cisco XR 12000 Series Router, the physical slot number can be 0 to 15, and there can be multiple SDRs, each of which is represented by an RP.
Page 51: User Groups, Task Groups, And Task Ids
User Access Privileges User Groups, Task Groups, and Task IDs The Cisco IOS XR software ensures security by combining tasks a user wants to perform (task IDs) into groups, defining which router configuration and management functions users can perform. This policy is enabled by the definition of: User groups—Collection of users that share similar authorization rights on a router.
Page 52: Predefined User Groups
(The root-lr user has the highest level of privileges in an SDR. In previous releases, SDRs were called logical routers [LRs].) Predefined User Groups Cisco IOS XR software includes a set of predefined user groups that meets the needs of most organizations. Table 3-2 describes predefined user groups.

Page 55: Navigating The Cisco Ios Xr Command Modes
Navigating the Cisco IOS XR Command Modes The Cisco IOS XR Software has different command modes. Each mode provides access to a subset of commands used to configure, monitor, and manage the router. Access to a mode is determined by your user group assignments.
Page 56: Identifying The Command Mode In The Cli Prompt
RP/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# When the router enters interface configuration submode, the prompt changes to include “(config-if)” after the router name: RP/0/0/CPU0:router(config)# interface POS 0/2/0/0 RP/0/0/CPU0:router(config-if)# Cisco IOS XR Getting Started Guide for the Cisco XR 12000 Series Router 3-44 OL-24755-01...
Page 57: Summary Of Common Command Modes
EXEC mode enables a basic set of commands to display the operational state of an SDR and the Cisco IOS XR software. Most CLI commands in EXEC mode do not change the SDR operation. The most common EXEC commands are show commands (to display SDR configuration or operational data) and clear commands (to clear or reset SDR counters).
Page 58 In the following example, the router enters the router configuration mode for BGP: RP/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# router bgp 140 RP/0/0/CPU0:router(config-bgp)# Cisco IOS XR Getting Started Guide for the Cisco XR 12000 Series Router 3-46 OL-24755-01...
