Setting a network configuration is a large task comprised of numerous administration activities.
Each of the configuration activities described can have an override applied to the original
configuration. Applying an override differentiates the device from the profile’s configuration and
requires careful administration to ensure this one device still supports the deployment
requirements within the network.
A profile’s network configuration process consists of the following:
• Overriding the DNS Configuration
• Overriding an ARP Configuration
• Overriding a L2TPv3 Profile Configuration
• Overriding IGMP Snooping Configuration
• Overriding a Quality of Service (QoS) Configuration
• Overriding a Spanning Tree Configuration
• Overriding a Routing Configuration
• Overriding a Dynamic Routing (OSPF) Configuration
• Overriding a Forwarding Database Configuration
• Overriding a Bridge VLAN Configuration
• Overriding a Cisco Discovery Protocol Configuration
• Overriding a Link Layer Discovery Protocol Configuration
• Overriding a Miscellaneous Network Configuration
• Overriding Alias Configuration
Overriding the DNS Configuration
Overriding the Network Configuration
Domain Naming System (DNS) DNS is a hierarchical naming system for resources connected to the
Internet or a private network. Primarily, DNS resources translate domain names into IP addresses.
If one 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 different 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).
To define the DNS configuration or apply overrides to an existing configuration:
Select Devices from the Configuration tab.
Select Device Overrides from the Device menu to expand it into sub menu options.
Select a target device from the device browser in the lower, left-hand, side of the UI.
Select Network to expand its sub menu options.
Select DNS.
