    By seamlessly integrating within the same chassis, the SIP-700 and Ethernet line cards provide true network and device convergence - a key design goal for the Cisco ASR 9000 Series of routers. The Cisco ASR 9000 SIP-700 only utilizes one line card slot within the Cisco ASR 9000 Series chassis, saving valuable line-card real estate.

  • Page 32: Management Interfaces

    The CLI is the primary user interface for configuring, monitoring, and maintaining routers that run Cisco IOS XR software. The CLI allows you to directly and simply execute Cisco IOS XR commands. All procedures in this guide use CLI. Before you can use other router management interfaces, you must first use the CLI to install and configure those interfaces.

  • Page 33: Simple Network Management Protocol

    Selecting and Identifying the DSC on Cisco ASR 9000 Series Routers A Cisco ASR 9000 Series Router supports up to two RSPs. If only one RSP is installed, that RSP automatically becomes the active RSP. If two RSPs are installed, the default configuration selects RSP0 as the active RSP.

  • Page 34: 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. Although typical router configuration and management take place using an Ethernet port, you must configure the console port for your LAN before it can be used.

  • Page 53: 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 54: Predefined User Groups

    Only the root-system users, root-lr users, or users associated with the WRITE:AAA task ID can Note configure task groups. Predefined User Groups Cisco IOS XR software includes a set of predefined user groups that meets the needs of most organizations. Table 3 describes predefined user groups.

  • Page 57: 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 58: Summary Of Common Command Modes

    EXEC mode enables a basic set of commands to display the operational state of an and the Cisco IOS XR software. Most CLI commands in EXEC mode do not change the operation. The most common EXEC commands are show commands (to display configuration or operational data) and clear commands (to clear or reset counters).
  • Page 59 Replace protocol with the keyword for the protocol to configure. Replace protocol_options with any keywords and arguments required for that protocol. In the following example, the router enters the router configuration mode for BGP: RP/0//CPU0:router# configure RP/0//CPU0:router(config)# router bgp 140 RP/0//CPU0:router(config-bgp)# Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide OL-28417-02...

  • Page 60: Entering Exec Commands From A Configuration Mode

    During normal operation, users do not interact with ROMMON. This mode is accessed only by manually interrupting the boot process and placing the system in ROMMON. Once in ROMMON, you can perform ROM Monitor tasks, including reinstallation of the Cisco IOS XR software, password recovery, and other diagnostic tasks.

  • Page 61: Managing Configuration Sessions

    To return to EXEC mode, enter the end command. Managing Configuration Sessions In the Cisco IOS XR software, you cannot change the running (active) configuration directly. Enter configuration changes into an inactive target configuration. When the target configuration is ready for use, you can apply that configuration to the router with the commit command.

  • Page 62: Displaying The Active Configuration Sessions

    Before you start a configuration session, you should check if there are other configuration sessions in progress. More than one user can open a target configuration session at a time, allowing multiple users to work on separate target configurations. Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide OL-28417-02...

  • Page 63: Starting A Configuration Session

    The target configuration is not a copy of the running configuration. It has only the configuration commands entered during the target configuration session. While in configuration mode, you can enter all Cisco IOS XR software commands supported in that configuration mode. Each command is added to the target configuration. You can view the target configuration by entering the show configuration command in configuration mode.

  • Page 64: Displaying Configuration Details With Show Commands

    To display the portion of the running configuration, connect to the appropriate and enter the show running-config command in EXEC or global configuration mode, as shown in the following example: RP/0//CPU0:router(config)# show running-config Building configuration... !!
