Description

Support for Software Maintenance Upgrade Package

Cisco IOS XE Catalyst SD-WAN Release 17.9.1a

Cisco vManage Release 20.9.1

This feature enables support for a Software Maintenance Upgrade (SMU) package that can be installed on Cisco IOS XE Catalyst SD-WAN devices. The SMU package provides a patch fix or a security resolution to a released Cisco IOS XE image. Developers can build this package that provides a fix for a reported issue without waiting for the fix to become available in the next release.

SMU Support for Cisco ISR1100 and ISR1100X Series Routers

Cisco IOS XE Catalyst SD-WAN Release 17.11.1a

Cisco vManage Release 20.11.1

Added support for Cisco ISR 1100 and ISR 1100X Series Integrated Services Routers.

Information About Software Maintenance Upgrade

A software maintenance upgrade (SMU) is a point fix for a critical bug in released software that attempts to minimize disruption to the router, if possible. An SMU is not designed to replace a maintenance release.

Cisco provides SMU fixes as package files, a file for each release and each component of Cisco Catalyst SD-WAN. The package contains metadata that describes the content of the package and the fix for a reported issue.

SMU Image Files

Each SMU image filename in the software repository includes a base image version and the defect ID related to the fix. In the image name:

  • base_image_version is the Cisco IOS XE image version.

  • defect_id is the identifier of the defect for which the SMU package has the fix.

SMU Types

An SMU type describes the effect of an installed SMU package on a Cisco IOS XE Catalyst SD-WAN device. The following are the SMU package types:

  • Hot SMU (non-reload): Enables an SMU package to take effect after an SMU image activation without rebooting (reloading) the Cisco IOS XE Catalyst SD-WAN device.

  • Cold SMU (reload): Enables an SMU package to take effect after rebooting (reloading) the Cisco IOS XE Catalyst SD-WAN device.

Benefits of Software Maintenance Upgrades

  • Allow you to address a network issue quickly while reducing the time and scope of the testing required. The Cisco IOS XE Catalyst SD-WAN device internally validates the SMU image compatibility and does not allow you to install non-compatible SMU packages.

  • Allow you to install or activate only one SMU package on devices at a time to simplify the initial implementation process.

  • Allow you to install an SMU package on multiple Cisco IOS XE Catalyst SD-WAN devices at the same time when installing using Cisco SD-WAN Manager. To install an SMU package on multiple devices using the CLI, ensure that you repeat the install process on multiple devices.

Manage Software Maintenance Upgrade Images

Use Cisco SD-WAN Manager to add, upgrade and activate, or deactivate and remove an SMU image.


Note

When you activate or deactivate an SMU image, the device may reboot, depending on the SMU image. A non-reload SMU type does not trigger a device reboot; a reload SMU type triggers a device reboot.

Add, View, and Activate an SMU Image

  1. Add an SMU image using the Cisco SD-WAN Manager software repository.

    See the Cisco SD-WAN Manager Add Software Images to Repository procedure in the ​Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide.

  2. View SMU images using the Cisco SD-WAN Manager software repository.

    See theCisco SD-WAN Manager View Software Images procedure in the ​Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide. Note the following points when viewing SMU images:

    • The Available SMU Versions column displays the number of SMU images available for the current base image version (Cisco IOS XE image version).

    • View the defects that are associated with an SMU image by clicking a desired entry in the Available SMU Versions column. In the Available SMU Versions dialog box, you can view the defect ID, the corresponding SMU version, and the SMU types, such as non-reload or reload.

    • In the Available SMU Versions dialog box, delete an SMU version by clicking the delete icon next to an SMU version.

  3. Upgrade an SMU image using the Cisco SD-WAN Manager software upgrade window.

    See the Cisco SD-WAN Manager Upgrade the Software Image on a Device procedure in the ​Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide. Note the following points about the SMU image that you choose to upgrade:

    • In the devices table, the Available SMUs column displays the number of SMU images that are available for the current base image version.

    • View a list of all available SMU versions and the upgrade images for a device by clicking a desired entry under the Available SMUs column. In the Available SMUs dialog box, you can view the SMU versions, SMU types, and the state of an SMU version.

      The SMU version is in the format base_image_version.cdet_id.

    • In the Upgrade dialog box, optionally check Activate and Reboot to activate an SMU image and perform a reboot of the Cisco IOS XE Catalyst SD-WAN device automatically.

      After you check the Activate and Reboot check box, Cisco SD-WAN Manager installs and activates the SMU image on a device and triggers a reload based on the SMU type. For more Information about activating a software image, see the Cisco SD-WAN Manager Activate a Software Image procedure in the ​Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide.

    After a successful upgrade of an SMU image, the Cisco IOS XE Catalyst SD-WAN device sends a corresponding success message.

Deactivate or Remove an SMU Image

Deactivate an SMU image and remove the image from a device using the Delete a Software Image procedure in the ​Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide.

Install and Activate an SMU Image Using the CLI

Device reboot:

When you activate an SMU image, the device may reboot, depending on the SMU image. A non-reload SMU type does not trigger a device reboot; a reload SMU type triggers a device reboot.

Before you begin

  • Download an SMU image from Cisco:

    Download an SMU image for your release from the Cisco site, https://software.cisco.com.

  • Upload an SMU image:

    Upload an SMU image to make it available for installation.

    • Upload an SMU image by adding the image to the device software repository using Cisco SD-WAN Manager. For more information about adding, viewing, and activate an SMU image, see Manage Software Maintenance Upgrade Images.

    • Upload an SMU image by copying the image to the bootflash of your device using the CLI.

Procedure

Step 1

Use the copy command to upload the SMU image from the file server to the bootflash of the device.

Step 2

If not already configured, configure the time limit for confirming that an SMU image activation is successful.

The range is 1 to 60 minutes. We recommend a time limit of at least 15 minutes.

Device# config-transaction 
Device(config)# system 
Device(config-system)# upgrade-confirm minutes

Step 3

Install an SMU image from the bootflash of your device and perform a compatibility check for the device and SMU package version.

Device# request platform software sdwan smu install file-path

Step 4

Use the show install summary command to confirm that the SMU image is installed.

If the request platform software sdwan smu install command was successful, the IMG row of the command output shows the build number. Make note of the version number. Use this as the build number in a subsequent step. 

Device# show install summary

Step 5

Use the show install package command with | include Defect ID to display the defect ID of the issue addressed by the SMU image. 

show install package bootflash:filename | include Defect ID

The command output shows the defect ID.

Step 6

Activate the SMU image on a Cisco IOS XE Catalyst SD-WAN device. For the build number, use the five-part build number displayed in a previous step. For the SMU defect ID, use the defect ID displayed in a previous step. 

Device# request platform software sdwan smu activate build-number.smu-defect-id

Step 7

Confirm the upgrade of the SMU image within the configured confirmation time limit.

Device# request platform software sdwan smu upgrade-confirm

Note

 

If you don’t issue this command on the device within the time limit that is specified in the upgrade-confirm minutes command, the device automatically reverts to the state that it was in before the SMU image activation.

Step 8

Use the show install summary command to confirm that the image is activated. For the IMG and SMU rows, the St column shows the letter C to indicate that the image is activated and committed.

Example

The following commands configure an upgrade confirmation time limit of 15 minutes.

Device# config-transaction
Device(config)# system
Device(config-system)# upgrade-confirm 15

The following commands install and activate an SMU image, and confirm that the image is successfully activated.

What to do next

If the SMU image is compatible with the Cisco IOS XE software image on the device, the upgrade task is successful and the SMU image is installed and activated on the device. If the upgrade task is not successful, the device automatically reverts to the state that it was in before the SMU image activation.

Deactivate and Remove an SMU Image Using the CLI

  • Device reboot:

    When you deactivate an SMU image, the device may reboot, depending on the SMU image. A non-reload SMU type does not trigger a device reboot; a reload SMU type triggers a device reboot.

  • Failed deactivation:

    If the SMU image deactivation on a device fails, the device automatically reverts to the state that it was in before the image deactivation.

Before you begin

Deactivate an image before removing:

Ensure that you deactivate the SMU image before you remove it.

Procedure

Step 1

If not already configured, configure the time limit for confirming that a SMU image deactivation is successful.

The range is 1 to 60 minutes. We recommend a time limit of at least 15 minutes.

Device# config-transaction 
Device(config)# system 
Device(config-system)# upgrade-confirm minutes

Step 2

Deactivate an SMU image on a Cisco IOS XE Catalyst SD-WAN device. 

Device# request platform software sdwan smu deactivate build-number.smu-defect-id

Step 3

Verify that the SMU image is deactivated. In the SMU line of the command output, in the St column, the letter D indicates deactivated. 

Device# show install summary

Step 4

Complete the SMU image deactivation.

Device# request platform software sdwan smu upgrade-confirm

If you do not issue this command on the device within the time limit specified in the upgrade-confirm minutes command, the image deactivation fails and the device automatically reverts to the state that it was in before the SMU image deactivation.

Step 5

Verify that the SMU image is inactive. In the SMU line of the command output, in the St column, the letter I indicates inactive.

Device# show install summary

Step 6

Get the version number of the image.

  1. Use the show install package command to display the version number. 

    show install package bootflash:filename | include Version

  2. The Version line of the output shows several numbers separated by periods. Copy the first five numbers of the version.

    For example, if the output shows 17.12.03.0.27.1717035922..Dublin, copy 17.12.03.0.27. Use this as the build number in a subsequent step.

Step 7

Use the show install package command with | include Defect ID to display the defect ID of the issue addressed by the SMU image. 

show install package bootflash:filename | include Defect ID

The command output shows the defect ID.

Step 8

Remove the SMU image from the device.

Device# request platform software sdwan smu remove build-number.smu-defect-id

Step 9

Verify that the SMU image has been removed. If successful, the command output does not have an SMU line for the removed SMU image. 

Device# show install summary

Example

The following commands configure an upgrade confirmation time limit of 15 minutes.

Device# config-transaction
Device(config)# system
Device(config-system)# upgrade-confirm 15

The following commands inactivate and uninstall an SMU image, and confirm that the image is removed.

Device# request platform software sdwan smu deactivate 17.12.03.0.3740.CSCwj48209
