Before enabling a Cisco UCS Manager domain for Cisco Intersight connectivity, you must configure the DNS servers and the NTP servers for the domain. The DNS servers are required to resolve the hostname of the Cisco Intersight service (svc.intersight.com) and the NTP servers are required to synchronize the time between the Cisco UCS Manager and the Cisco Intersight service. These settings ensure that the Cisco UCS Manager can establish a secure and reliable connection with the Cisco Intersight service and register the domain with the Cisco Intersight account.
