Install Guide

9. Click the IPv4 Settings tab and do the following:
a. Select Manual or Automatic (DHCP) from the Method drop-down list.
b. If you select the Manual method, click Add, and then enter the valid IP address, Netmask (in the CIDR format), and
gateway details. It is recommended to use the static IP in case if you want to control over the priority of the DNS servers
(primary and secondary DNS entries).
Typically, vSphere elements of data center such as vCenter and ESXi hosts are managed using hostname or FQDN.
iDRAC, CMC, and OME-Modular are managed using IP addresses. In this case, Dell EMC recommends you to configure
the DNS settings only for the vSphere network.
If both vSphere network and iDRAC management network are managed by using hostname or FQDN, DNS server must
be configured in such a manner that it resolves the hostname or FQDN for both the networks. For more information, see
the CentOS documentation.
NOTE:
The last configured DNS server becomes the primary DNS irrespective of which network the DNS is
configured for.
c. Enter the DNS server IP and domains to be searched for in the DNS Servers and Search Domains boxes respectively.
d. Select the Require IPV4 addressing for this connection to complete check box and click SAVE.
e. If you do not want to use this network as the default network (gateway), click Routes, and then select the Use this
connection only for resources on its network check box.
NOTE:
Adding multiple networks as default gateways may result in network issues and OMIVV functions may get
affected.
f. If you want to reach to any external network using the known gateways, click Add on the same page, and then add the
network IP address, netmask (in the CIDR format), and gateway details.
