Perform Preliminary Checks

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:

Verify Status of Hardware Modules

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.

Before you begin

Ensure that all required hardware modules have been installed on the router.

Procedure

Verify Node Status

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.

Procedure

Step 1

show platform

Example:

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

The show platform command when executed from the XR EXEC mode displays the status of XR console running on various RPs and LCs. 

RP/0/RP0/CPU0:ios#show platform

RP/0/RP0/CPU0:ios#

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:


RP/0/RP0/CPU0:router# admin

Enters mode.

Step 3

show platform

Example:

sysadmin-vm:0_RP0#show platform

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:

  • OPERATIONAL—Card is operating normally and is fully functional

  • POWERED_ON—Power is on and the card is booting up

  • FAILED—Card is powered on but has experienced some internal failure

  • PRESENT—Card is in the shutdown state

  • OFFLINE—User has changed the card state to OFFLINE. The card is accessible for diagnostics

Software states:

  • OPERATIONAL—Software is operating normally and is fully functional

  • SW_INACTIVE—Software is not completely operational

  • FAILED—Software is operational but the card has experienced some internal failure

Verify Software Version

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.

Procedure

show version

Example:

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

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.

Example

What to do next

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.

Verify Firmware Version

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.

Procedure

show hw-module fpd

Example:

RP/0/RP0/CPU0:N560_SYSPSV#show hw-module fpd

Note

 

Ensure that the CFP2-DCO firmware version is also compatible with Cisco IOS XR Release 7.2.1.

Note

 

To upgrade firmware on CFP2-DCO, controller optics (R/S/I/P) must be shut down.

Displays the list of hardware modules detected on the router.

Note

 

This command can be run from both XR VM and System Admin VM modes.

In the above output, some of the significant fields are:

  • FPD Device—Name of the hardware component, such as IO FPGA, IM FPGA, and BIOS.

  • Status—Upgrade status of the firmware. The different states are:

    • CURRENT—The firmware version is the latest version.

    • READY—The firmware of the FPD is ready for an upgrade.

    • NOT READY—The firmware of the FPD is not ready for an upgrade.

    • NEED UPGD—A newer firmware version is available in the installed image. It is recommended that an upgrade be performed.

    • RLOAD REQ—The upgrade has been completed, and the ISO image requires a reload.

    • UPGD DONE—The firmware upgrade is successful.

    • UPGD FAIL—The firmware upgrade has failed.

    • BACK IMG—The firmware is corrupted. Reinstall the firmware.

    • UPGD SKIP—The upgrade has been skipped because the installed firmware version is higher than the one available in the image.

  • Running—Current version of the firmware running on the FPD.

  • Programmd—Version of the FPD programmed on the module.

What to do next

  • 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.

Verify Interface Status

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.

Procedure

show ipv4 interface summary

Example:

RP/0/RP0/CPU0:router#show ipv4 interface summary

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.

In the above result:

  • Assigned— An IP address is assigned to the interface.

  • Unnumbered— Interface which has borrowed an IP address already configured on one of the other interfaces of the router.

  • Unassigned—No IP address is assigned to the interface.

You can also use the show interfaces brief and show interfaces summary commands in the XR EXEC mode to verify the interface status.
