Page 11 A Cisco CRS-1 router can consist of an extensive hierarchy of racks, logical routers, shelves, cards, and ports. The Cisco CRS-1 router is shipped with one default logical router (LR). An LR is a collection of line cards, Route Processors, and other assignable or configurable resources, such as interfaces specific to your network that together form a complete router within the Cisco CRS-1 router system.

Connecting and Communicating with the Router To manage or configure a router running the Cisco IOS XR software, you must first connect to the router using a terminal or a PC. Connections are made either through a direct physical connection to the Console port of the primary Route Processor (RP), or from a remote location using a modem or Ethernet connection.

Page 40: Summary Of Common Command Modes
Common Command Modes and CLI prompts Command Mode Description EXEC Logging in to a router running the Cisco IOS XR software automatically places the router in EXEC mode. Example: RP/0/RP0/CPU0:router# EXEC mode enables a basic set of commands to display the operational state of the router and examine the state of an operating system.
Page 41 RP/0/RP0/CPU0:router(config)# router bgp 140 RP/0/RP0/CPU0:router(config-bgp)# address-family ipv4 multicast RP/0/RP0/CPU0:router(config-bgp-af)# For more information, refer to the Cisco IOS XR Routing Configuration Guide and the Cisco IOS XR Routing Command Reference.

Page 42: Entering Exec Commands From A Configuration Mode
Common Command Modes and CLI prompts (continued) Command Mode Description Administration EXEC The Cisco IOS XR software provides a separate administration EXEC mode for users with the and administration appropriate access permissions. This mode is used primarily to display system-wide parameters, configuration modes configure the administration plane over the control Ethernet, and configure LRs on multiple-chassis systems.
Page 43: Command Mode Navigation Example
Step 3 If you belong to a user group that has configuration privileges, you can place the router in the global configuration mode by entering the configure command: RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# Cisco CRS-1 Series Carrier Routing System Getting Started Guide 2-13...
Page 44: Managing Configuration Sessions
To return to EXEC mode, enter the end command. Managing Configuration Sessions In the Cisco IOS XR software, the running (active) configuration can never be altered directly. All configuration changes are entered into an inactive target configuration, which must be explicitly committed to the running configuration.
Page 45: Stage 1: Enter Configuration Changes To The Nonactive Target Configuration
Make changes to the target configuration. These changes do not affect the running configuration. The Step 2 CLI automatically verifies the syntax of your commands, and allows only valid entries: RP/0/RP0/CPU0:router(config)# interface POS 0/2/0/1 RP/0/RP0/CPU0:router(config-if)# description faq RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.10.10.10 255.0.0.0 Cisco CRS-1 Series Carrier Routing System Getting Started Guide 2-15...

Page 175: Rp Redundancy And Failover
Determining the Primary RP During system startup, the first RP to boot with a valid Cisco IOS XR software boot package becomes the active “primary RP.” The primary RP can in either slot RP0 or slot RP1. You can tell which RP is the primary RP in the following ways: The primary RP can be identified by the green Primary LED on the faceplate of the card.
Page 176: Role Of The Standby Rp
If the primary RP fails or goes off line for any reason, the standby RP immediately takes control of the system. Summary of Redundancy Commands RP redundancy is enabled by default in the Cisco IOS XR software, but you can use the commands described in Table 7-3 to display the redundancy status of the cards, or force a manual failover.
Page 177: Manual Failover
Chapter 7 RP Redundancy and Hardware Administration on Cisco IOS XR Software RP Redundancy and Failover You should not use the reset command to force an RP failover, because the result could be a significant Caution loss of router operations. Instead, use the redundancy failover command to fail over to the standby RP, then use the hw-module node nodeID reset command to reset the RP.
Page 178: Communicating With A Standby Rp
Reloading, Shutting Down, or Power Cycling a Node Use the commands described in this section to reload the Cisco IOS XR software on the primary RP or on any specified node in the system. This section also describes the commands used to administratively shut down a node, and to power a node on or off.
Page 179: Reloading The Primary Rp
Because the reload command causes the primary RP to go offline and either reload Caution Cisco IOS XR software or enter ROM monitor mode, the router experiences a loss of service unless a redundant standby RP is installed and in “ready” state. To display the status of the standby RP, type the show redundancy command in EXEC mode.
Page 180: Administratively Shutting Down Or Powering On Or Off A Node
A node can be administratively shut down using the hw-module node nodeID shutdown command. A node that is shut down still has power, but cannot load or run the Cisco IOS XR software. You can also administratively turn power off for a node using the hw-module node nodeID power command.

Page 200: Configuration Errors At Startup
Memory Warnings in Configuration Sessions The Cisco IOS XR software automatically monitors and manages the system resources in a router. Under normal operating conditions, memory problems should not occur. When a low-memory issue does occur, it is often in the form of a low-memory warning during a configuration session.
