See the following topics for more information on the configuration pages available 
in the IP Configuration > Domain Name System menu.

To resolve a hostname to an IP address, the client contacts one or more DNS 
servers. DNS servers can be learned dynamically if the management interface is 
configured as a DHCP client (see 

). You can also use the 

DNS Servers page to statically configure DNS servers.

DNS client functionality is enabled by default.

To configure the DNS server mode and global settings:

Click IP Configuration > Domain Name System > DNS Servers in the navigation 
window.

Select Enable to implement DNS client functionality on the switch, if it is not 
already enabled.

Enter the following parameters:

•

Default Domain Name—Specify a domain name to be used to complete an 
unqualified hostname. For example, finance.yahoo.com is a fully qualified 
domain name. If only the unqualified hostname, finance, is specified, the 
default domain name yahoo.com would be appended, with a period in 
between. In your entry, do not include the period that separates the 
unqualified hostname from the domain name. The range is 1–255 
alphanumeric characters.

•

Domain retry—Specify the number of times to retry sending DNS queries. 
The range is 0–100 and the default value is 2 times.

•

Domain timeout—Specify the time in seconds that the switch waits for a 
response to a DNS query. The range is 0–3600 seconds and the default is 
3 seconds.
