Overriding a Profile’s Network Configuration
Domain Naming System (DNS) DNS is a hierarchical naming system for resources connected to the
Internet or a private network. Primarily, the controller or service platform’s DNS resources translate
domain names into IP addresses. If a DNS server doesn't know how to translate a particular
domain name, it asks another one until the correct IP address is returned. DNS enables access to
resources using human friendly notations. DNS converts human friendly domain names into
notations used by networking equipment for locating resources.
As a resource is accessed (using human-friendly hostnames), it’s possible to access the resource
even if the underlying machine friendly notation name changes. Without DNS you need to
remember a series of numbers (123.123.123.123) instead of a domain name
(www.domainname.com).
Controllers and service platforms maintain their own DNS facility that can assist in domain name
translation. A DNS assignment can be overridden as needed, but removes the device configuration
from the managed profile that may be shared with other similar device models.
To define the DNS configuration or apply overrides to an existing configuration:
1. Select Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service
platforms or Access Points.
2. Select a target device (by double-clicking it) from amongst those displayed within the Device
Configuration screen.
Devices can also be selected directly from the Device Browser in the lower, left-hand, side of
the UI.
3. Select Profile Overrides from the Device menu to expand it into sub menu options.
4. Select Network to expand its sub menu options.
