Only universalk9 images are supported. After onboarding and determining the mode of operation, changing from Controller mode to Autonomous mode or vice-versa, results in the loss of configuration. The reset button does not function to restore a golden image or configuration in controller mode. If DHCP discovers an attempt to install using either of these processes, a mode change to Autonomous mode is triggered.

If this trustpoint is deleted for any reason, you can generate and load a new trustpoint by rebooting the device. The new key may be different than the deleted one. Download the router-model -universalk9. Manually creating the VM using the. Booting the CSR v Instance. This feature introduces support for managing a Cisco Catalyst V Edge software platform hosted in the OpenStack cloud computing platform "Train" release.

Download the Cisco Catalyst V software image that is appropriate for your method of deployment. Do not choose an ISO image. Have the image ready to upload to the Cisco vManage software image repository. The file name begins with: cv-universalk9. When starting the device in controller mode, boot the device using the bootflash:packages. We recommend a clean install of the Cisco Catalyst V. This ensures support for all features, provides the most up-to-date licensing, and ensures that devices and the controller stay synchronized.

Note the following:. Performing the upgrade in Cisco vManage preserves the configuration of the device s being upgraded. Download the device serial number file provisioning file from PnP and upload it to Cisco vManage. The devices are now available on Cisco vManage. You can also use the Sync Smart Account option on vManage to sync the device with your virtual account and populate the device in Cisco vManage. For more information, refer to the Plug and Play Support Guide.

The PnP-based discovery process determines the mode in which the device operates, based on the controller discovery and initiates a mode change, if required. The mode change results in a reboot of the device. Once reboot is complete, the device performs appropriate discovery process. This feature enables a device to automatically learn about the available IP addresses and default gateway information when a DHCP server is not available.

If an IP address that the device learns allows a successful connection to the PnP server, the device continues with the PnP onboarding process. In addition, the DNS server must have an ip name-server value of 8. For automatic IP address detection, a device uses 8. The PnP process then attempts to reach devicehelper. This feature is supported only in a simple 30 bit network mask Layer 2 network in which one PE router and one customer edge router are in the same VLAN. If the device is running a pre If ciscosdwan.

After the device boots up in controller mode, the configuration present in the configuration file is applied. If a ciscortr. The bootstrap file ciscosdwan. Use the controller-mode command in Privileged EXEC mode to switch between controller and autonomous modes. The controller-mode disable command switches the device to autonomous mode. The controller-mode enable command switches the device to controller mode. If device is booted with bundle mode Super packages , after reboot, the image gets automatically expanded and activated to prepare the router for SDWAN operation.

If there is a previous SD-WAN configuration file present on the device, the device boots in controller mode. Before performing an upgrade, ensure that you remove any stale SD-WAN configuration files from bootflash. Use the controller-mode enable command to switch from autonomous to controller mode and the controller-mode disable command to switch from controller mode to autonomous mode.

To switch modes using CLI, ensure that the appropriate configuration files mentioned in the table below are present. After the device boots up, the configuration present in the configuration file is applied. The device reads the configuration file and uses the configuration information to come up on the network. When the device mode is switched from autonomous to controller, the startup configuration and the information in NVRAM certificates , are erased. This action is equivalent to running the write erase command.

When the device mode is switched from controller to autonomous, all Yang-based configuration is preserved and can be reused if you switch back to controller mode. When the device is in Day N configuration and is reloaded, the presence of a bootstrap file does not impact the device operating mode.

If you use request platform software sdwan config reset or request platform software sdwan software reset commands to bring the device back to controller-mode day-zero configuration, the device performs one of the following actions:.

Performs mode discovery. Uses the appropriate configuration file to perform bootstrap. For the changes to take effect, you must reload the router after running the CLI. Running this CLI ensures the configuration for the currently installed version is wiped along with crypto keys and the device enters the day zero workflow after the reload. If the device is not set up to use PnP for onboarding, then it reads the configuration file in the bootflash and uses the configuration information to come up on the network.

If the device is setup to use PnP onboarding, then after reload, the PnP discovery will start again. In the case of public clouds, just like a fresh install, additional bootstrap configuration is provisioned that allows you to login to the instance. Failure to follow save the bootstrap file in these environments cause loss of virtual machine connectivity. Configuration is not be restored. Device is reverted to Day zero configuration. Previous running configuration is stored in bootflash.

When you switch from autonomous mode to controller mode, and switch back to autonomous mode, the Cisco IOS XE configuration is not restored because the startup configuration is empty. You have to manually restore configuration from the backup.

CDB contents are erased for subsequent mode switches and Cisco IOS configuration are not restored as startup configuration is empty. If the device is in controller mode, the show sdwan running-config command does not display the following information:. Configurations under line VTY except for transport, access-class, and ipv6 access-class. To verify these configuration use the show running-config command. Before beginning this procedure, ensure that you have access to the Cisco CSRV or Cisco Catalyst V router through the currently configured console access method.

The image used for deploying the Cisco CSRV or Cisco Catalyst V software determines the default type of console access to use, which can be virtual or serial. The procedure includes changing the mode from controller to autonomous, and then back to controller, which is required for operation with Cisco SD-WAN. These mode changes cause the device to reload.

Disable controller mode. Enter the following command and follow the prompts to complete the command. After the device restarts, enter enable to enter privileged EXEC mode. This option specifies that the device console is detected automatically.

This is the default setting during the initial installation boot process. Change the device back to controller mode. In this upgrade procedure, Cisco vManage saves the device configuration before the upgrade. If the configuration on the device, that is modified using CLI is not same as on Cisco vManage, then the device has inconsistent configuration after the upgrade.

For example, if you configure the BGP AS number of a device to a different value using CLI, the device can have inconsistent configuration and the upgrade fails. Therefore, we recommend that you upgrade the device using Cisco vManage. An interface that is configured with a higher preference value has a higher priority. We recommend using Cisco vManage to upgrade.

This keeps devices and the controller synchronized. If it is necessary to upgrade using the CLI, use the following steps. Use these following steps to make configuration file copies before performing the manual upgrade process. Without these steps, the router will lose its configuration during the upgrade.

If the deployment is on a public cloud service, such as Amazon Web Services AWS , failure to save the configuration before upgrading manually can cause an unrecoverable loss of connectivity with the device. In contrast to a hardware device, there may be no way to gain any type of console access to the virtual router. Verify the upgrade using request platform software sdwan software upgrade-confirm.

From In controller mode, use the config-transaction command to enter global configuration mode. The configuration terminal command is not supported in Controller mode. Device boots up in autonomous mode and configuration is preserved via startup configuration. Activate the image. This resets the device, deleting any existing configuration.

The device starts in day zero configuration. If necessary, remove an existing software image to provide space for loading a new software image. Activate the new image. Device boots up with ucmk9 image and configuration is restored if the uckm9 image was previously installed on the device. Downgrading to a fresh install of old image versions brings the device to Day 0 configuration.

To proceed, use the clean option at activation. To downgrade from controller mode to earlier IOS XE images, switch to autonomous mode and follow the downgrade process. The smart licensing authorization is lost when a device switches from autonomous to controller mode and back to autonomous mode again. Register the device using license smart register idtoken token force command in privileged EXEC mode. Set the required crypto throughput using platform hardware throughput crypto crypto-value.

Save the configuration using write memory in privileged EXEC mode. Reload the device and verify that the new crypto throughput value is applied using the show platform hardware throughput crypto command. Enable the reservation mode using the license smart reservation command in global configuration mode.

Save the configuration using write memory. The Task View page opens, showing the progress as Cisco vManage creates logical devices. The Chassis Number column shows the unique identifier for each logical device. For the logical devices that you have created, click … and choose Generate Bootstrap Configuration. The Generate Bootstrap Configuration dialog box shows the content of the bootstrap configuration, which includes the UUID of the logical device, and includes the configuration details provided by the device template if you have attached one.

Copy a valid image on the Flash as described in the procedures provided in this document. Your first step in the upgrade procedure is to select the correct Cisco IOS software release and feature set. This step is very important, and these factors can affect the decision for which Cisco IOS you should select:. Interfaces and modules support: You must ensure that the new Cisco IOS supports all the interfaces and modules in the router.

The file system type "flash" or "disk" is used to store the Cisco IOS image. The show file system command output shows the list of file systems available on the router. It should have sufficient space to store the Cisco IOS image. This method saves time if you must roll back the Cisco IOS. Backup the configuration from the router because some of the Cisco IOS releases add default configurations.

This newly added configuration may conflict with your current configuration. Compare the configuration of the router after the Cisco IOS upgrade with the configuration backed up before the upgrade. If there are differences in the configuration, you must ensure they do not affect your requirements. In order to achieve this connection, the router interface and the TFTP server must have an IP address in the same range or a default gateway configured. Cisco recommends that you keep a backup of the router and access server configuration before you upgrade.

However, this situation might happen if the right steps are not followed properly. Note: In this section you are presented with three examples that describe how to copy the Cisco IOS image. You can use any one of these methods in order to copy the image. Upgrade the new image from a TFTP server. Use the copy tftp: flash: command in order to copy the image from TFTP server to the flash.

The copy process takes several minutes. This time differs from network to network. When the copy process is in progress, messages are displayed that indicate which file has been accessed. The exclamation point "! Each exclamation point indicates that ten packets have transferred successfully. A checksum verification of the image occurs after the image is written to Flash memory.

If you choose the slot1: file systems, use the copy tftp: slot1: command in order to copy the image from TFTP server to slot1. You can configure a router as TFTP server. If you choose the flash: file systems, use the copy tftp: flash: command in order to copy the image from TFTP server to flash.

The value is displayed in the last line of the show version output. It should be set to 0x IOS image in the flash —If the first file in the Flash is not the Cisco IOS Software image, but a configuration file, or something else, then you need to configure a boot system statement in order to boot the specified image. Otherwise, the router tries to boot with the configuration file or the first file in the Flash, which does not work.

Use the show version command in order to verify the Cisco IOS software. Contents Introduction. Step Save the Configuration and Reload the Router.
