Default DNS Configuration
Table 4-2 shows the default DNS configuration.
Setting Up DNS
Beginning in privileged EXEC mode, follow these steps to set up your switch to use the DNS:
Table 4-2 Default DNS Configuration
Feature Default Setting
DNS enable state Enabled.
DNS default domain name None configured.
DNS servers No name server addresses are configured.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 ip domain-name name Define a default domain name that the software uses to complete unqualified
host names (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.
Step 3 ip name-server server-address1
[server-address2 ...
server-address6] Specify 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 switch sends DNS
queries to the primary server first. If that query fails, the backup servers are
queried.
Step 4 ip domain-lookup (Optional) Enable DNS-based host name-to-address translation on your switch.
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).
Step 5 end Return to privileged EXEC mode.
Step 6 show running-config Verify your entries.
Step 7 copy running-config
startup-config (Optional) Save your entries in the configuration file.
