Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters global configuration mode.
Defines a default domain name that the software
uses to complete unqualified hostnames (names
without a dotted-decimal domain name).
Do not include the initial period that separates
an unqualified name from the domain name.
At boot time, no domain name is configured;
however, if the device configuration comes
from a BOOTP or Dynamic Host Configuration
Protocol (DHCP) server, then the default
domain name might be set by the BOOTP or
DHCP server (if the servers were configured
with this information).
Specifies the address of one or more name
servers to use for name and address resolution.
You can specify up to six name servers.
Separate each server address with a space. The
first server specified is the primary server. The
device sends DNS queries to the primary server
first. If that query fails, the backup servers are
queried.
(Optional) Enables DNS-based
hostname-to-address translation on your device.
This feature is enabled by default.
If your network devices require connectivity
with devices in networks for which you do not
control name assignment, you can dynamically
assign device names that uniquely identify your
devices by using the global Internet naming
scheme (DNS).
Returns to privileged EXEC mode.
