Device controllability is a system-level process on Cisco DNA Center that enforces state synchronization for some device-layer features. Its purpose is to aid in the deployment of network settings that Cisco DNA Center needs to manage devices. Changes are made on network devices when running discovery, when adding a device to inventory, or when assigning a device to a site.

In the Provision Status column, click See Details. When Cisco DNA Center configures or updates devices, the transactions are captured in the audit logs, which you can use to track changes and troubleshoot issues. Device controllability is enabled by default. If you do not want device controllability enabled, disable it manually. For more information, see Configure Device Controllability.

When device controllability is disabled, Cisco DNA Center does not configure any of the preceding credentials or features on devices while running discovery or when the devices are assigned to a site.

At the time of the network settings creation on the site, if device controllability is enabled, the associated devices are configured accordingly. The following circumstances dictate whether or not device controllability configures network settings on devices:. In the current release, the following IPDT commands are configured for any newly discovered device:.

Update Site Telemetry Changes : The changes made to any settings that are under the scope of device controllability are applied to the network devices during device provisioning or when the Update Telemetry Settings action is performed, even if device controllability is not enabled. Device controllability aids deployment of the required network settings that Cisco DNA Center needs to manage devices.

To manually disable device controllability, do the following:. Uncheck the Enable Device Controllability check box. You must accept the end-user license agreement EULA before downloading software or provisioning a device. If you have not yet configured cisco. The system supports multiple cloud access keys.

See Configure the Proxy. You must download and install the package from a catalog server. For more information, see Download and Install Packages and Updates. It takes several minutes to synchronize with the cloud platform. Inventory collection is scheduled to occur at the default interval.

Integrity Verification IV monitors key device data for unexpected changes or invalid values that indicate possible compromise, if any, of the device. The objective is to minimize the impact of a compromise by substantially reducing the time to detect unauthorized changes to a Cisco device.

To provide security integrity, Cisco devices must be verified as running authentic and valid software. Currently, Cisco devices have no point of reference to determine whether they are running authentic Cisco software. The KGV file is posted at:. The KGV file is imported into IV and used to verify integrity measurements obtained from the network devices.

Device integrity measurements are made available to and used entirely within the IV. Connectivity between IV and cisco. If it is automatically downloaded, the value is System. The Import Latest from Cisco option does not require a firewall setup.

If you clicked Import Latest from Cisco , a connection is made to cisco. After the import is finished, verify the current KGV file information in the UI to ensure that it has been updated. IV automatically downloads the latest KGV file from cisco. The auto downloads continue every 7 days. For example, if a new KGV file is available on a Friday and the auto download is every 7 days on a Monday , you can download it manually. Status : The status of the KGV scheduler's last attempt.

The effect of importing a KGV file can be seen in the Image Repository window, if the images that are already imported have an Unable to verify status physical or virtual.

Click the System tab and verify the information to ensure that your external IP address manager configuration succeeded. To assist in troubleshooting service issues, you can change the logging level for the Cisco DNA Center services. A logging level determines the amount of data that is captured in the log files. Each logging level is cumulative; that is, each level contains all the data generated by the specified level and higher levels, if any. For example, setting the logging level to Info also captures Warn and Error logs.

We recommend that you adjust the logging level to assist in troubleshooting issues by capturing more data. For example, by adjusting the logging level, you can capture more data to review in a root cause analysis or RCA support file. The default logging level for services is informational Info. You can change the logging level from informational to a different logging level Debug or Trace to capture more information.

Due to the type of information that might be disclosed, logs collected at the Debug level or higher should have restricted access. The total compressed size of the log files is 2 GB. If the log files exceed 2 GB, the newer log files overwrite the older ones. The Debugging Logs window displays the following fields:. From the Services drop-down list, choose a service to adjust its logging level. This is an advanced feature that has been added to control which software components emit messages into the logging framework.

Use this feature with care. Misuse of this feature can result in loss of information needed for technical support purposes. Log messages will be written only for the loggers packages specified here. By default, the Logger Name includes packages that start with com. You can enter additional package names as comma-separated values.

Do not remove the default values unless you are explicitly directed to do so. From the Logging Level drop-down list, choose the new logging level for the service. Cisco DNA Center supports the following logging levels in descending order of detail:. From the Timeout field, choose the time period for the logging level.

Configure logging-level time periods in increments of 15 minutes up to an unlimited time period. If you specify an unlimited time period, the default level of logging should be reset each time a troubleshooting activity is completed.

Or, you can update the polling interval at the device level for a specific device by choosing Device Inventory. When you set the polling interval using the Network Resync Interval , that value takes precedence over the Device Inventory polling interval value.

Make sure that you have devices in your inventory. If not, discover devices using the Discovery feature. In the Resync Interval field, enter a new time value in minutes.

Optional Check the Override for all devices check box to override the existing configured polling interval for all devices. Audit logs also capture information about device public key infrastructure PKI notifications. The information in these audit logs can be used to assist in troubleshooting issues, if any, involving the applications or the device PKI certificates. Audit logs also record system events that occurred, when and where they occurred, and which users initiated them.

With audit logging, configuration changes to the system get logged in separate log files for auditing. The Audit Logs window appears, where you can view logs about the current policies in your network.

Click the timeline slider to specify the time range of data you want displayed on the window:. To specify a custom range, click By Date and specify the start and end date and time.

Each audit log can be a parent to several child audit logs. By clicking the arrow, you can view a series of additional child audit logs. Optional From the list of audit logs in the left pane, click a specific audit log message. The audit log displays the Description , User , Interface , and Destination of each policy in the right pane.

We strongly recommend that you follow these security recommendations:. If you have separate management and enterprise networks, connect Cisco DNA Center 's management and enterprise interfaces to your management and enterprise networks, respectively. Doing so ensures network isolation between services used to administer and manage Cisco DNA Center and services used to communicate with and manage your network devices.

If deploying Cisco DNA Center in a three-node cluster setup, verify that the cluster interfaces are connected in an isolated network. Replace the self-signed server certificate from Cisco DNA Center with the certificate signed by your internal certificate authority CA.

Upgrade Cisco DNA Center with critical upgrades, including security patches, as soon as possible after a patch announcement. Cisco DNA Center is configured to access the internet to download software updates, licenses, and device software, as well as provide up-to-date map information, user feedback, and so on.

Providing internet connections for these purposes is a mandatory requirement. Restrict the ingress and egress management and enterprise network connections to and from Cisco DNA Center using a firewall, by only allowing known IP addresses and ranges and blocking network connections to unused ports. This IP address connects the appliance to the external network.

Enter the following command to check the TLS version currently enabled on the cluster. If you want to change the TLS version on the cluster, enter the following commands. If RC4 and TLS minimum versions are set, they are listed in the env: of the magctl service display kong command. If these values are not set, they do not appear in the env:. If you want to disable the RC4-SHA ciphers that you enabled previously, enter the following command on the cluster.

In some network configurations, proxy gateways might exist between Cisco DNA Center and the remote network it manages containing various network devices.

Therefore, the network devices located within these remote networks can only communicate with Cisco DNA Center through the proxy gateway. In network topologies where a proxy gateway is present between Cisco DNA Center and the remote network it manages, perform the following procedure to import a proxy gateway certificate in to Cisco DNA Center.

You should have the certificate file that is currently being used by the proxy gateway. The certificate file contents should consist of any of the following:. The certificate used by the devices and the proxy gateway must be imported in to Cisco DNA Center by following this procedure.

In the Proxy Certificate window, view the current proxy gateway certificate data if it exists. To add a proxy gateway certificate, drag and drop the self-signed or CA certificate into the Drag and Drop Here area. Additionally, private keys are neither required nor uploaded into Cisco DNA Center for this procedure.
