DNS
Understanding
Domain Name System (DNS) servers can be configured on the unit to facilitate the resolution of domain
names to IP addresses.
NOTE: Manual configuration of DNS overrides any DNS settings obtained via DHCP.
Configuring
The following example shows how to configure a DNS server with IP address 192.168.1.2 on the MCR.
Note that the “search” option can take a list of arguments and in this example, there are two arguments;
mds
and
gemds.
admin@(none) 00:31:02% set system dns server 192.168.1.2 search [ mds gemds ] options attempts 3
timeout 3
Monitoring
Ensure the CLI is in operational mode. Follow the example below to view the state and statistics.
The ping utility can be used on the CLI when it is in operational mode to verify that DNS is working prop-
erly. If ping can resolve a name on the connected network to an IP address then DNS settings are working
properly. The example below shows the resolution of the name “example.com” to the IP address
“192.0.43.10” on a unit that is connected to the Internet.
Use the control sequence “CTRL-C” to stop the ping utility.
admin@(none) 00:20:33> ping example.com
PING example.com (192.0.43.10) 56(84) bytes of data.
