Hi @tikshoret

Fastest thing to do is kill your current reservation and spin up a new one. If the problem persists, we can troubleshoot.

hi tikshoret,

dnac talks to nodes via snmp. dnac talks to ise via pxgrid. u need to make sure px grid is available. if not then u need to re-establish trust via ise and dnac which works ok. ise can be configured to talk to the nodes via radius. we can look to configure ping for u if its needed for ur work, but right now is an issue. we can look to this after the holiday break.
