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, LCs, 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
| Step1 | admin Example:Enters System Admin EXEC mode.
| ||
| Step2 | show platform Example:
Displays the list of hardware modules detected on the router. From the result, verify that all the hardware modules installed on the chassis are listed. If a module is not listed, it indicates either that module is malfunctioning, or it is not properly installed. Remove and reinstall the hardware module. | ||
| Step3 | show hw-module fpd Example:Displays the list of hardware modules detected on the router. |
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
| Step1 | 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. |
| Step2 | admin Example:Enters mode. |
| Step3 | 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 FCs,) 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 FC and FTs should be "OPERATIONAL". Various hardware and software states are listed here. Hardware states:
Software states:

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 versionDisplays 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
Cisco IOS XR Software, Version <release-version>Copyright (c) 2013-2017 by Cisco Systems, Inc.Build Information:Built By : <user>Built On : <date and time stamp>Build Host : iox-lnx-030Workspace : /x.x.x/ncs540/wsVersion : <release-version>Location : /opt/cisco/XR/packages/cisco NCS-540 () processorSystem uptime is 1 day, 16 hours, 18 minutesWhat 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:
| Note | This command can be run from both XR VM and System Admin VM modes. |
| Note | Only the following Cisco NCS 540 router variants support the System Admin mode:
|
In the above output, some of the significant fields are:
-
FPD Device- Name of the hardware component such as FPD, CFP, and so on.
-
ATR-Attribute of the hardware component. Some of the attributes are:
-
B- Backup Image
-
S-Secure Image
-
P-Protected Image
-
-
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.
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 summaryWhen 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.
-
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.
Verify SDR Information
Secure domain routers (SDRs) divide a single physical system into multiple logically-separated routers. SDRs are also known as logical routers (LRs). On the router, only one SDR is supported. This SDR is termed the default-sdr. Every router is shipped with the default-sdr, which owns all RPs installed in the routing system. An instance of this SDR runs on line cards and route processors. Complete this task to verify the details of the SDR instances.
Note | Only the following Cisco NCS 540 router variants support the System Admin mode:
|
Procedure
| Step1 | admin Example:Enters mode. |
| Step2 | show sdr Example:Displays the SDR information for every node. |
What to do next
If you find SDR is not running on a node, try reloading the node. To do that, use the hw-module location node-id reload command in the System Admin EXEC mode.
