I observed a couple of things about this lab which I think might be improved.
1) After provisioning of the sandbox leaf switches were not reachable. I assumed this is done by purpose for people to play with LAN automation part. If that's correct then having a small tutorial which mentions this would really help.
2) ISE is not integrated into DNAC. Moreover SSH credentials which are required for ISE onboarding into DNAC are not provided. So basically from 5 devices we can only work with 2. Would be good to either have ISE already integrated or keep to possibility to do it on our own.
3) There is a button to redeploy a vm from image (developer box). It is also possible to restart ISE server. Would be great if we can have some sort of reset or redeploy option for the HW switches or lab overall. The use case for this is when someone messed up the lab (like I just did unintentionally) they could have an option to reset it.
Thanks a lot for giving us opportunity to play with the new technologies.
