Enable DNS-Based Device Discovery

You can discover (add) devices based on DNS host name if you populate the DNS_SERVER_IP variable in the xvmconf file.

About this task

If you add your DNS server information to the xvmconf file and then install Visibility Manager, you can then add devices to Visibility Manager based on host name, rather than by IP address, which is the default method. Visibility Manager stores the DNS server information and uses it to resolve host names and obtain connectivity.

Important

• You must delete the DNS_SERVER_IP variable if you do not need support for DNS-based discovery.
• DNS-based discovery is supported only for IPv4 addresses.

The xvmconf file is included in the xvm-<version-build>.tar file.

1. Download and untar the xvm-<version-build>.tar file.
   For more information, see Download and Untar the Build.
2. Open xvmconf in a text editor.
3. Find the DNS_SERVER_IP variable and change it as follows.
   

   DNS_SERVER_IP=<DNS-server-ipv4-addr>

   

   Important

   You must delete the DNS_SERVER_IP variable if you do not need support for DNS-based discovery.
