Device DNS
About
What is Device DNS?
The DNS screen is used to input the IP address of the DNS server that the TR7 ASP device will connect to. Multiple DNS servers can be added. Additionally, virtual host groups can also be defined on this screen.
Helpful Information
For TR7 ASP devices operating in a cluster, it's not necessary to perform DNS settings separately. Changes made in the interface of the TR7 ASP device selected as the 1st device are automatically passed to the 2nd TR7 ASP device.
