The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

After successfully logging into the console, you must perform some preliminary checks to verify the default setup. If any setup issue is detected when these checks are performed, take corrective action before making further configurations. These preliminary checks are:
Hardware modules include RPs, fan trays, and so on. On the router, multiple hardware modules are installed. Perform this task to verify that all hardware modules are installed correctly and are operational.
Ensure that all required hardware modules have been installed on the router.
|
show platform Example: |
Each card on the router represents a node. The operational status of the node is verified using the show platform command. This command is to be executed independently from both XR and System Admin mode CLIs.
|
Step 1 |
show platform Example:The show platform command when executed from the XR EXEC mode displays the status of XR console running on various RPs and LCs. Verify that all RPs are listed and their state is OPERATIONAL. This indicates that the XR console is operational on the cards. |
|
Step 2 |
admin Example:Enters mode. |
|
Step 3 |
show platform Example:The show platform command when executed from the System Admin EXEC mode displays the status of all hardware units like cards (RPs, IMs ) and hardware modules (fan trays) on the router. This is an example for single-chassis system: Verify that all cards installed on the router are displayed in the result. The software state of LCs/IMs and RPs and the hardware state of FTs and power modulesshould be "OPERATIONAL". Various hardware and software states are listed here. Hardware states:
Software states:
|
The following commands display the environmental parameters. Execute these commands independently from both XR and System Admin mode commands.
|
Step 1 |
show environment temperatures Example: |
|
Step 2 |
show environment fan Example: |
The router is shipped with the Cisco IOS XR software pre-installed. Verify that the latest version of the software is installed. If a newer version is available, perform a system upgrade. This will install the newer version of the software and provide the latest feature set on the router.
Perform this task to verify the version of Cisco IOS XR software running on the router.
|
show version Example:Displays the version of the various software components installed on the router. The result includes the version of Cisco IOS XR software and its various components. |
Verify the result to ascertain whether a system upgrade or additional package installation is required. If that is required, refer to the tasks in the chapter Perform System Upgrade and Install Feature Packages.
The firmware on various hardware components of the router must be compatible with the Cisco IOS XR image installed. Incompatibility might cause the router to malfunction. Complete this task to verify the firmware version.
|
show hw-module fpd Example:
In the above output, some of the significant fields are:
|
Upgrade the required firmware by using the upgrade hw-module location all fpd command in the EXEC mode. For the FPD upgrade to take effect, the router needs a power cycle.
 Note |
BIOS and IOFPGA upgrades require power cycle of the router for the new version to take effect. |
After the router has booted, all available interfaces must be discovered by the system. If interfaces are not discovered, it might indicate a malfunction in the unit. Complete this task to view the number of discovered interfaces.
|
show ipv4 interface summary Example:When a router is turned on for the first time, all interfaces are in the 'unassigned' state. Verify that the total number of interfaces displayed in the result matches with the actual number of interfaces present on the router.
You can also use the show interfaces brief and show interfaces summary commands in the XR EXEC mode to verify the interface status. |
