DNS

Path: Administration > Network > DNS > options

Use the options under DNS to configure and test the Domain Name System (DNS):

Select Primary DNS Server or Secondary DNS Server to specify the IPv4 or IPv6 addresses of the primary and optional secondary DNS server. For the Rack PDU to send e-mail, you must at least define the IP address of the primary DNS server.

The Rack PDU waits up to 15 seconds for a response from the primary DNS server or secondary DNS server (if specified). If the Rack PDU does not receive a response within that time, e-mail cannot be sent. Use DNS servers on the same segment as the Rack PDU or on a nearby segment (but not across a wide-area network [WAN]).

Define the IP addresses of the DNS servers then enter the DNS name of a computer on your network to look up the IP address for that computer to verify correct operation.

Host Name: Configure a host name here and a domain name in the Domain Name field then users can enter a host name in any field in the NMC interface (except e-mail addresses) that accepts a domain name.

Domain Name (IPv4): Configure the domain name here only. In all other fields in the NMC interface (except e-mail addresses) that accept domain names, the NMC adds this domain name when only a host name is entered.

To override all instances of the expansion of a specified host name by the addition of the domain name, set the domain name field to its default, somedomain.com, or to 0.0.0.0.

To override the expansion of a specific host name entry, include a trailing period. The NMC recognizes a host name with a trailing period (such as mySnmpServer.) as if it were a fully- qualified domain name and does not append the domain name.

Domain Name (IPv6): Specify the IPv6 domain name here.

Select test to send a DNS query that tests the setup of your DNS servers:

As Query Type, select the method to use for the DNS query:

by Host: the URL name of the server

by FQDN: the fully-qualified domain name

by IP: the IP address of the server

by MX: the Mail Exchange used by the server

As Query Question, identify the value to be used for the selected query type:
