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.

•Verifying the System After Initial Boot
•Where to Go Next
Prerequisites
The following sections describe the software and hardware requirements for bringing up a standalone system running Cisco IOS XR Software Release 4.1.
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 4.1. 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
"Related Documents" section on page x.
Hardware Prerequisites and Documentation
The Cisco IOS XR software runs on the routers listed in the "Supported Standalone System Configurations" section on page 1-1. 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 "Related Documents" section on page x.
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
|
|
|
Step 1 |
Establish a connection to the DSC Console port. |
Initiates communication with the router. •For instructions on connecting to the Console port, see the "Connecting to the Router Through the Console Port" section on page 1-15. •After you have successfully connected to the router through the Console port, the router displays the prompt: Username: •If the Username prompt appears, skip this procedure and continue the general router configuration as described in Chapter 5, "Configuring Additional Router Features." |
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
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.
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
|
|
|
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. |

•show version Command: Example

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 Chapter 4, "Configuring General Router Features."
The following EXEC mode example displays the nodes assigned to the default SDR, which is called the owner SDR:
