1. I added my switches into dna, some C9300L and some C2960+.
2. After that I wanted to enable "Wired Endpoint Data Collection" and I enabled it on the my site (Enable Cisco DNA Center Wired Endpoint Data Collection At This Site)
3. I started the task "Update Telemetry Settings"
4. It was good for C2960+ because dnac did it for all ports that were needed

but not for the C9300L, because dnac only did this for some ports (I had about 300 ports where I assumed dnac was supposed to do this)
I have no idea why.... the config of ports the same on the c9300L and С2960+
