IP Resolver

GigaVUE‑FM must be configured with DNS server and default search domains in order to add and manage the nodes by their Fully Qualified Domain Names (FQDN).

This configuration is not mandatory to manage normal nodes/clusters, however 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 left navigation pane, click and select System > IP Resolver.
2. Enter the following details, as required. Use the +/- icon to add the additional servers and domains.



DNS Server

IP address of the domain name server. GigaVUE-FM allows you to configure only three name servers. The Add Server option is disabled once you have configured three name servers.

Note:  If GigaVUE-FM is configured with DHCP and three or more nameservers are assigned from DHCP itself, then the Add Server option is disabled in the UI.

Default Search Domain

Default search domain.

3. Click Save to save the configuration.
