Domain Name System configuration

The Domain Name System (DNS) Configuration commands are used for defining the primary and secondary DNS servers on your local network, and for setting the default domain name served by the switch services. DNS parameters must be configured prior to using hostname parameters with the ping, traceroute, and tftp commands.

The following table describes the Domain Name System (DNS) Configuration commands.

Table 99 Domain Name System (DNS) Configuration commands

Command

Description

[no] ip name-server <IP address>

Sets the IP address for your primary DNS server. Use dotted

 

decimal notation.

 

Command mode: Global configuration

[no] ip name-server <IP address>

Sets the IP address for your secondary DNS server. If the
