Skip to content. One has been runnig well since I purchased it. The second one, that I just got in the mail, keeps rebooting even if I load the same code and all the same.
Even with empty code, keeps rebooting. It repeats forever. I'm programming with Arduino IDE. I do the same in both ESP32's, one runs fine, the other continuously resets. On my second purchase, I bought 5 esp When first plugged, they list all parameters on the Serial interface, and no rebooting.
The goal of the switch configuration API is to provide a common basis to build re-usable and extensible switch drivers with the following ideas in mind:. It is based on Generic Netlink to allow for each switch driver to easily extend the swconfig API without causing major core parts rework each and every time someone has a specific feature to implement and offers a central configuration point with a well-defined API.
Certain switches, however, also need distributed switch architecture DSA. DSA's development was parallel to swconfig, written by the OpenWrt project. The main difference between swconfig and DSA is that DSA-supported switches show one network interface per port, whereas swconfig-configured switches show up as a single port, which limits the amount of information that can be extracted from the switch. For example, you cannot have per-port traffic statistics with swconfig.
That limitation is what led to the creation of the switchdev framework, when swconfig was proposed then refused for inclusion in mainline. 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.
There are different methods for loading the bootstrap configuration onto a CV instance on a cloud service. The method you use depends on the cloud service. We recommend to click Download in the Generate Bootstrap Configuration dialog box to save a copy of the bootstrap configuration.
When configuring the instance, use the bootstrap configuration that you created in Cisco vManage.
