Software installation requirements

Installing software on the router involves installing a consolidated package (bootable image) that consists of a bundle of subpackages, each controlling a different set of functions.

Upgrade software during a scheduled maintenance period when service interruption is acceptable. After upgrading the software, reboot the router to apply changes.

Cisco software licenses

Cisco software licensing is a system that enables activation and validation of Cisco IOS software feature sets through specific processes and components.

  • Licenses can be used to enable consolidated packages, technology packages, or individual features.

  • License files are stored in the bootflash of the router.

  • The IR8100 uses Smart Licensing Using Policy (SLP) for license management.

Understanding Cisco software licensing

Cisco software licensing consists of processes and components to activate Cisco IOS software feature sets by obtaining and validating Cisco software licenses.

Consolidated packages

Consolidated packages are image-based licenses used to activate all subsystems on the IR8100 router that correspond to a specific license. These licenses are enforced only at boot time.

  • Image-based licenses help bring up all subsystems related to the license.

  • Licenses are enforced only during the router's boot process.

  • Not all IOS-XE features may apply to the IR8100; some features may not be implemented or appropriate for this platform.

Available consolidated packages and feature applicability

To obtain software images for the IR8100 router, See Cisco Software Download page.

The following image-based licenses can be pre-installed on the IR8100 router:

  • Network-Essentials

  • Network-Advantage


Note

All of the IOS-XE feature set may not apply to the IR8100. Some features may not have been implemented yet, or are not appropriate for this platform. Details of the Network-Essentials and Network-Advantage contents can be found in the IR8100 product data sheet.

Network-Essentials packages

The Network-Essentials and Network-Essentials_npe technology is a baseline networking feature.

  • The Network-Essentials technology package includes baseline features and supports security features.

  • The Network-Essentials_npe package includes all features of Network-Essentials except payload encryption functionality.

  • The Network-Essentials_npe is available only in the Network-Essentials_npe image and helps fulfill export restriction requirements.

Differences between Network-Essentials and Network-Essentials_npe packages

The main difference between the Network-Essentials and Network-Essentials_npe packages is the presence or absence of payload encryption features such as IPsec and Secure VPN.

Network-Advantage packages

Network-Advantage is a Cisco technology that provides advanced network features.

  • The Network-Advantage technology package includes all crypto features.

  • The Network-Advantage_npe package (npe = No Payload Encryption) includes all features of Network-Advantage except payload-encryption functionality.

  • The Network-Advantage_npe package is available only in the Network-Advantage_npe image to fulfill export restriction requirements.

Feature differences between Network-Advantage and Network-Advantage_npe

The main difference between the Network-Advantage and Network-Advantage_npe packages is the set of payload-encryption-enabling features such as IPsec and Secure VPN.

Install Cisco IOS XE release

When the device boots up with the Cisco IOS XE image for the first time, it checks the installed version of the ROMMON and upgrades if the system is running an older version. During the upgrade, do not power cycle the device. The system automatically power cycles the device after the new ROMMON is installed.

After the installation, the system will boot up with the Cisco IOS XE image as normal.


Note
When the device boots up for the first time and if the device requires an upgrade, the entire boot process may take several minutes. This process will be longer than a normal boot due to the ROMMON upgrade.

Procedure

Step 1

Use the configure terminal command to enter the global configuration mode.

Example:


            Router# 
            configure terminal
            Router(config)#boot sys bootflash:ir8100-universalk9.BLD_V175_THROTTLE_LATEST_20210221_233814_V17_5_0_172.SSA.bin
            Router(config)#config-register 0x2102
            Router(config)#exit
            Router#

Step 2

Use the show romvar command to verify the ROMMON variables and license configuration.

Example:


            Router# 
            show romvar
            ROMMON variables:
            PS1 = rommon ! >
            THRPUT =
            LICENSE_BOOT_LEVEL = network-advantage,all:IR8100;
            RET_2_RTS =
            CONSOLE_LOCK = 0
            BOOT = flash:ir8100-universalk9.BLD_V175_THROTTLE_LATEST_20210221_233814_V17_5_0_172.SSA.bin,12;
            BSI = 0
            RET_2_RCALTS =
            RANDOM_NUM = 1294606670

Step 3

Use the show run | inc license command to display all lines in the running configuration that contain the word "license".

Example:

Router#
            show run | inc license
            no license feature hseck9
            license udi pid IR8140H-P-K9 sn FDO2441J91D
            license boot level network-advantage
            Router#

Step 4

Use the reload ? command to reload the device and verify the image.

Example:


            Router#reload ?
            /noverify  Don't verify file signature before reload.
            /verify    Verify file signature before reload.
            at         Reload at a specific time/date
            cancel     Cancel pending reload
            in         Reload after a time interval
            pause      Pause during reload
            reason     Reload reason
            <cr>       <cr>

Step 5

Use the reload /verify command to verify the image.

Example:

Router#
            reload /verify
            Verifying file integrity of bootflash:ir8100-universalk9.BLD_V175_THROTTLE_LATEST_20210221_233814_V17_5_0_172.SSA.bin............

ROMMON image software packages

A ROMMON image is a software package used by ROM Monitor (ROMMON) software on a router. The software package is separate from the consolidated package normally used to boot the router.

  • ROMMON images are independent software packages for the ROM Monitor.

  • They are separate from the main consolidated package used to boot the router.

  • ROMMON images can be upgraded independently of the main software package.

ROMMON Image Release and Upgrade Information

An independent ROMMON image (software package) may occasionally be released and the router can be upgraded with the new ROMMON software. For detailed instructions, see the documentation that accompanies the ROMMON image.


Note

A new version of the ROMMON image is not necessarily released at the same time as a consolidated package for a router.

Autogenerated file directories and files

This section discusses the autogenerated files and directories that can be created, and how the files in these directories can be managed.

Table 3. Autogenerated files

File or directory

Description

crashinfo files

Crashinfo files can appear in the bootflash: file system.

These files provide descriptive information of a crash and may be useful for tuning or troubleshooting purposes. However, the files are not part of router operations, and can be erased without impacting the functioning of the router.

core directory

Storage area for .core files.

If this directory is erased, it will automatically regenerate itself at bootup. The .core files in this directory can be erased without impacting any router functionality, but the directory itself should not be erased.

managed directory

This directory is created on bootup if a system check is performed. Its appearance is completely normal and does not indicate any issues with the router.

tracelogs directory

The storage area for trace files.

Trace files are useful for troubleshooting. If the Cisco IOS process fails, for instance, users or troubleshooting personnel can access trace files using diagnostic mode to gather information related to the Cisco IOS failure.

Trace files are not part of router operations; you can erase them without affecting the router's performance.

Key points about autogenerated directories

Important information about autogenerated directories include:

  • Autogenerated files on the bootflash: directory should not be deleted, renamed, moved, or altered in any way unless directed by Cisco customer support.


    Note
    Altering autogenerating files on the bootflash: may have unpredictable consequences for system performance.

  • Crashinfo files and files in the core and tracelogs directory can be deleted.

Flash storage

Subpackages are installed to local media storage, such as flash.

For flash storage, use the dir bootflash: command to list the file names.


Note
Flash storage is required for successful operation of a router.
