DNS Push Notifications Configuration Settings
DNS Push Notifications comes with pre-configured settings, but it is not enabled by default. To use DNS Push Notifications, the Push Notifications (push-notifications) attribute must be enabled at the DNS server level and on the desired zone(s). DNS Push Notifications can be enabled on any Cisco Prime Network Registrar DNS server that hosts the zone you want notifications on. This can be primary or secondary zone.
Note |
DNS server must be reloaded for DNS Push Notification changes to take effect. |
