Bringing Up the Cisco IOS XR Software on a Standalone Router

This chapter provides instructions for bringing up the Cisco IOS XR software on a standalone router for the first time. This section applies to standalone routers that are delivered with Cisco IOS XR software installed.

Prerequisites

The following sections describe the software and hardware requirements for bringing up a standalone system.

Software Requirements

The system requires compatible ROM Monitor firmware on all RPs.


Caution The ROM Monitor firmware on all RPs must be compatible with the Cisco IOS XR software release currently running on the router before a Cisco CRS system is upgraded to Cisco IOS XR Software Release 4.2. For minimum ROM Monitor requirements for Cisco IOS XR Software Release 3.2.0 and later releases, see the Software/Firmware Compatibility Matrix at the following URL: http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html

If the router is brought up with an incompatible version of the ROM Monitor software, the standby RP may fail to boot. For instructions to overcome a boot block in the standby RP in a single-chassis system, see Cisco IOS XR ROM Monitor Guide for the Cisco CRS Router. If a boot block occurs in a multishelf system, contact your Cisco Technical Support representative for assistance. See the “$paratext>” section.

Hardware Prerequisites and Documentation

The Cisco IOS XR software runs on the routers listed in the “Supported Standalone System Configurations” section. Before a router can be started, the following hardware management procedures must be completed:

  • Site preparation
  • Equipment unpacking
  • Router installation

For information on how to complete these procedures for your router equipment, see the hardware documents listed in the “$paratext>” section.

Bringing Up and Configuring a Standalone Router

To bring up a standalone router, connect to the router and configure the root-system username and password, as described in the following procedure:

SUMMARY STEPS

1. Establish a connection to the DSC Console port.

2. Type the username for the root-system login and press Enter.

3. Type the password for the root-system login and press Enter.

4. Log in to the router.

DETAILED STEPS

 

Command or Action
Purpose

Step 1

Establish a connection to the DSC Console port.

Initiates communication with the router.

Step 2

Type the username for the root-system login and press Enter.

Sets the root-system username, which is used to log in to the router.

Step 3

Type the password for the root-system login and press Enter.

Creates an encrypted password for the root-system username.

Note This password can be changed with the secret command.

Step 4

Retype the password for the root-system login and press Enter.

Allows the router to verify that you have entered the same password both times.

  • If the passwords do not match, the router prompts you to repeat the process.

Step 5

Log in to the router.

Establishes your access rights for the router management session.

  • Enter the root-system username and password that were created earlier in this procedure.
  • After you log in, the router displays the CLI prompt, which is described in the CLI Prompt.

Examples

The following example shows the root-system username and password configuration for a new router, and it shows the initial log in:

--- Administrative User Dialog ---
Enter root-system username: username1
Enter secret:
Enter secret again:
RP/0/RP0/CPU0:Jan 10 12:50:53.105 : exec[65652]: %MGBL-CONFIG-6-DB_COMMIT :
'Administration configuration committed by system'. Use 'show configuration
commit changes 2000000009' to view the changes.
Use the 'admin' mode 'configure' command to modify this configuration.
User Access Verification
Username: username1
Password:
RP/0/RP0/CPU0:router#

The secret line in the configuration command script shows that the password is encrypted. When you enter the password during configuration and login, the password is hidden.

Verifying the System After Initial Boot

To verify the status of the router, perform the following procedure:

SUMMARY STEPS

1. show version

2. admin

3. show platform [ node-id ]

4. exit

5. show redundancy

6. show environment

DETAILED STEPS

Command or Action
Purpose

Step 1

show version

 

RP/0/RP0/CPU0:router# show version

Displays information about the router, including image names, uptime, and other system information.

Step 2

admin

 

RP/0/RP0/CPU0:router# admin

Places the router in administration EXEC mode.

Step 3

show platform [ node-id ]

 

RP/0/RP0/CPU0:router(admin)# show platform

Displays information about the status of cards and modules installed in the router.

  • Some cards support a CPU module and service processor (SP) module. Other cards support only a single module.
  • A card module is also called a node. When a node is working properly, the status of the node in the State column is IOS XR RUN. The status of the supported SPA interface is OK.
  • The show platform node-id command is used to display information for a specific node. Replace node-id with a node name from the show platform command Node column.

Note To view the status of all the cards and modules, the show platform command must be executed in administration EXEC mode.

Step 4

exit

 

RP/0/RP0/CPU0:router(admin)# exit

Exits the administration EXEC mode.

Step 5

show redundancy

 

RP/0/RP0/CPU0:router# show redundancy

Displays the state of the primary (active) and standby (inactive) RPs, including the ability of the standby to take control of the system.

  • If both RPs are working correctly, one node displays active role, the Partner node row displays standby role, and the Standby node row displays Ready.

Step 6

show environment

 

RP/0/RP0/CPU0:router# show environment

Displays information about the hardware attributes and status.

Examples of show Commands

The following sections provide examples of show commands:

show version Command: Example

The following example shows how to display basic information about the router configuration by entering the show version command in EXEC mode.

show platform Command: Example

The show platform command displays information on router resources. In EXEC mode, the show platform command displays the resources assigned to the secure domain router (SDR) that you are managing. In administration EXEC mode, the show platform command displays all router resources.


Note Secure Domain Routers (SDRs) are introduced in Chapter4, “Configuring General Router Features”


The following EXEC mode example displays the nodes assigned to the default SDR, which is called the owner SDR :

show environment Command: Example

To display environmental monitor parameters for the system, use the show environment command in EXEC or administration EXEC mode. The show environment [options] command syntax is used.

Enter the show environment ? command to display the command options.
