Defining DNS Servers

The DNS Servers Page enables configuring the DNS servers and the default

domain used by the switch.

To configure DNS servers:

STEP 1 Click IP Configuration > Domain Name System > DNS Servers. The DNS

Servers Page opens.

STEP 2 Enter the parameters.

• DNS—Select to enable the switch as a DNS client to resolve DNS names into

IP addresses through one or more configured DNS servers.

• Default Domain Name—Enter the default DNS domain name (1–158

characters). The switch appends to all non-fully qualified domain names

(FQDN) turning them into FQDNs.

• Type—Displays the default domain type options:

DHCP

—The default domain name is dynamically assigned by the DHCP

server.

Static

—The default domain name is user-defined.

- N/A—No default domain name.

DNS Server Table:

• DNS Server—The IP addresses of the DNS servers. Up to eight DNS servers

can be defined.

• Server State—The active DNS server. There can be only one active server.

Each static server has a priority, a lower value means a higher priority. When

first time the request is sent, static server with lowest priority is chosen. If

after two retries there is no response from this server, the next server with

the next lowest priority is selected. If none of the static servers respond, the

first dynamic server on the table, sorted by IP address (low to high), is

selected.

STEP 3 Click Add. The Add DNS Server Page opens.

STEP 4 Enter the parameters.

• IP Version—Select Version 6 for IPv6 or Version 4 for IPv4.
