on the same channel simultaneously).

Path: Administration > Network > DNS > options
Use the options under DNS on the left navigation menu 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 Management Card to send e-mail, you must
at least define the IP
address of the primary DNS server.
– The Management Card waits up to 15 seconds for a response from the primary DNS server or
the secondary DNS server (if a secondary DNS server is specified). If the Management Card
does not receive a response within that time, e-mail cannot be sent. Therefore, use DNS
servers on the same segment as the Management Card or on a nearby segment (but not across
a wide-area network [WAN]).
– After you define the IP addresses of the DNS servers, verify that DNS is working correctly by
entering the DNS name of a computer on your network to look up the IP address for that
computer.
• Host Name: After you configure a host name here and a domain name in the Domain Name field,
users can enter a host name in any field in the Management Card interface (except e-mail
addresses) that accepts a domain name.
• Domain Name (IPv4): You need to configure the domain name here only. In all other fields in the
Management Card interface (except e-mail addresses) that accept domain names, the
Management Card 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 (for example, when defining a trap
receiver), include a trailing period. The Management Card 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
