Setting Up DNS
If you use the device IP address as its hostname, the IP address is used and no DNS query occurs. If you
configure a hostname that contains no periods (.), a period followed by the default domain name is appended
to the hostname before the DNS query is made to map the name to an IP address. The default domain name
is the value set by the
ip domain-name
global configuration command. If there is a period (.) in the hostname,
the Cisco IOS software looks up the IP address without appending any default domain name to the hostname.
Follow these steps to set up your switch to use the DNS:
