IP Resolver

GigaVUE-FM must be configured with DNS server and default search domains in order to add and manage the nodes by their FQDN. This configuration may not be mandatory to manage normal nodes/clusters but it is mandatory to manage the clusters behind NAT.

The reason is GigaVUE-FM does not know the NAT IP of the member nodes of the cluster behind NAT. It can only learn the private IP and hostname through the device APIs. GigaVUE-FM cannot reach the nodes behind NAT with their private address. GigaVUE-FM uses the hostname to contact the nodes in the cluster. Host names must therefore be resolved to NAT IP using the IP Resolver page, failure to do so will result in failure in node specific operations.

You can configure the domain name server and search domains from the IP Resolver page as follows:

1.

On the right side of the top navigation bar, click .

2.

On the left navigation pane, select System > NAT Configuration > IP Resolver.

3.

Enter the following details, as required. Use the +/- icon to add the additional servers.

Field	Description
DNS Server	Domain name server
Default Search Domain	Default search domain

4.

Click Save to save the configuration.
