In a network that uses ClearPass and RADIUS CoA, a client first connects without profile information and receives limited access.
How does ClearPass make sure that the client ultimately receives full access?
DHCP data lets ClearPass profile and classify the endpoint after its initial restricted authentication. ClearPass can trigger a RADIUS CoA termination for the active session; the client then authenticates again, allowing policy evaluation to use the new profile and assign full access.
