Hi,
What is the reason DNAC reconfigures from time to time the SNMP and logging settings (I identified at least these 2 features)?
I see this on several DNAC deployments. Without visible reason to me, DNAC removes for example the "logging source-interface" command before re-adding a few seconds later. It does this for several network devices (but not all) at the same time.
In some environments it gives us some troubles (without mentioning https://community.cisco.com/t5/cisco-catalyst-center/router-provisioning-changes-ntp-source-interface/m-p/5163708/highlight/true#M10008 topic).

DNAC (Cisco DNA Center) might reconfigure SNMP and logging settings due to its automated management and optimization processes. It can adjust these settings to ensure compliance with its policies or to align with updates and changes in the network topology.
This reconfiguration can occur due to several factors, including:
If these changes are causing operational issues, it may be beneficial to review the configuration policies set within DNAC and ensure they align with your network requirements. Additionally, checking for any software updates or known issues in the version you are using could provide further insights into this behavior.

Not convinced. My devices are already discovered and are already configured with the right source-interface settings.

Force an assurance configuration push and do a 'generate configuration preview'... In the configuration preview, you will see Catalyst Center will always remove the SNMP/Syslog configuration and re-add it.

But why?
In my situation, during this small time frame (between the "no source-interface xxx" and the "source-interface xxx"), my devices may sends syslogs via another interface which trigger a security alert to our SOC team.
Is there any way to change this behaviour? I was thinking about disabling Device Controllability but maybe not the best idea.
