Page 82 Verifying Fabric Cabling Connections Figure 3-5 shows the faceplate of the CRS-FCC- LED panel. The CRS-FCC-LED is also called an optical interface module (OIM) LED panel. This panel goes into slot LM0 or LM1 in a fabric card chassis.The OIM LED panel provides connectivity information on how the fabric chassis cards are functioning in the multishelf system.
Page 83 Chapter 3 Bringing Up the Cisco IOS XR Software on a Multishelf System Figure 3-5 Because the OIM LED panel is present only in the fabric card chassis, the LEDs indicate the status of the bundles in the fabric card chassis only. Therefore, if a connection is wrong, the equipment assumes that the connection at the line card chassis is fixed, and the connection at the fabric card chassis is the one that needs to be relocated to the correct position as indicated by the LEDs.
Page 84 Verifying Fabric Cabling Connections The following description helps explain the states of LEDs on the OIM LED panel. In cables should connect an LCC S13 card to the FCC S2 card as follows: A0 to J0, A1 to J1, and A2 to J2. Instead, A1 is incorrectly connected to J2.

Connecting and Communicating with the Router SDRs perform routing functions in the same manner as a physical router, but share some chassis resources with the rest of the system. For example, the applications, configurations, protocols, and routing tables assigned to an SDR belong to that SDR only, but other functions, such as chassis control, switch fabric, and partitioning, are shared with the rest of the system.

Chapter 4 Configuring General Router Features Starting a Configuration Session When you place the router in global configuration mode or administration configuration mode using the configure command, a new target configuration session is created. The target configuration allows you to enter, review, and verify configuration changes without impacting the running configuration. The target configuration is not a copy of the running configuration;...
Page 112: Starting An Exclusive Configuration Session
Managing Configuration Sessions Starting an Exclusive Configuration Session An exclusive configuration session allows you to configure the administration configuration or an SDR and lock out all users from committing configuration changes until you are done. Other users can still create and modify a target configuration, but they cannot commit those changes to the running configuration until you exit your exclusive configuration session.
Page 113 Chapter 4 Configuring General Router Features In EXEC and global configuration mode, you can view the SDR configuration for the SDR to which you are connected. When you are connected to the DSC and operating in administration EXEC and administration configuration mode, you can view the administration configuration, which includes hardware assignments for SDRs and multishelf systems.

Page 117 Chapter 4 Configuring General Router Features Displaying a Combined Target and Running Configuration Although the target and running configurations remain separate until the target configuration is committed, you can preview the combined target and running configuration without committing the changes. The combined configuration shows what the new running configuration will look like after the changes from the target configuration are committed.
Page 118 Managing Configuration Sessions Displaying Configuration Error Messages and Descriptions Configuration changes are automatically verified during the commit operation, and a message is displayed if one or more configuration entries fail. To display an error message and description for a failed configuration, enter the show configuration failed command. You can view configuration errors only during the current configuration session.
Page 119: Saving The Target Configuration To A File
Chapter 4 Configuring General Router Features Saving the Target Configuration to a File Target configurations can be saved to a separate file without committing them to the running configuration. Target configuration files can then be loaded at a later time and further modified or committed.
Page 120: Clearing All Changes To A Target Configuration
Managing Configuration Sessions Clearing All Changes to a Target Configuration To clear changes made to the target configuration without terminating the configuration session, enter the clear command in global configuration mode or administration configuration mode. This command deletes any configuration changes that have not been committed. In the following example, the user configures an interface but does not commit it.

Chapter 4 Configuring General Router Features In the preceding example, the show configuration command displays the target configuration, which includes the failed configuration. Note The failed configuration is discarded if you exit global configuration mode or administration configuration mode without recovering the configuration. After recovery, correct and commit the configuration or save it to a file to avoid losing it.
Page 124: Aborting A Configuration Session
Configuring the SDR Hostname If you end a configuration session without committing the configuration changes, the router prompts you to save changes, discard changes, or cancel the action, as shown in the following example: RP/0/RP0/CPU0:router(config-if)# end Uncommitted changes found, commit them before exiting(yes/no/cancel)?

Page 148: Configuration Limiting
Configuration Limiting Configuration Limiting The Cisco IOS XR software places preset limits on the configurations you can apply to the running configuration of a router. These limits ensure that the router has sufficient system resources (such as RAM) for normal operations. Under most conditions, these preset limits are sufficient. In some cases, for which a large number of configurations is required for a particular feature, it may be necessary to override the preset configuration limits.

Configuration Error Messages Configuration Failures During a Commit Operation A target configuration is added to the running configuration of a router when the commit command is entered. During this operation, the changes are automatically verified by the other components in the system.
Page 185: Memory Warnings In Configuration Sessions
Chapter 7 Troubleshooting the Cisco IOS XR Software 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.
Page 186: Displaying System Memory Information
Memory Warnings in Configuration Sessions “ERROR! MEMORY IS IN SEVERE (or CRITICAL) STATE” When the memory is in a severe or critical state, router operation and performance is likely to be affected. Regular users are not allowed to enter configuration mode. Only lr-root owners can enter configuration mode to free memory by removing configurations.

Page 194: Special Characters
Special Characters Special Characters Certain keyboard characters have special meaning when used in regular expressions. keyboard characters that have special meaning. Table A-1 Character _ (underscore) To use these special characters as single-character patterns, remove the special meaning by preceding each character with a backslash (\).
Page 195: A P P E N D I X A Understanding Regular Expressions, Special Characters, And Patterns
Appendix A Understanding Regular Expressions, Special Characters, and Patterns Multiple-Character Patterns Multiple-character regular expressions can be formed by joining letters, digits, and keyboard characters that do not have a special meaning. With multiple-character patterns, order is important. The regular expression a4% matches the character a followed by a 4 followed by a %. If the string does not have a4%, in that order, pattern matching fails.
Page 196: Pattern Alternation
Pattern Alternation The order for matches using multipliers (*, +, and ?) is to put the longest construct first. Nested constructs are matched from outside to inside. Concatenated constructs are matched beginning at the left side of the construct. Thus, the regular expression matches A9b3, but not 9Ab3 because the letters are specified before the numbers.
Page 197 Appendix A Understanding Regular Expressions, Special Characters, and Patterns Parentheses Used for Pattern Recall To create a regular expression that recalls a previous pattern, use parentheses to indicate memory of a specific pattern and a backslash (\) followed by a digit to reuse the remembered pattern. The digit specifies the occurrence of a parenthesis in the regular expression pattern.
