Example: To set the first IP address of the management-module DNS server to 192.168.70.29 and enable DNS on the primary management module that does not have IPv6 support, while management module 1 is set as the persistent command environment, at the system:mm[1]> prompt, type 
                  dns -i1 192.168.70.29 -on
To display the DNS status of the primary management module, while management module 1 is set as the persistent command environment, at the system:mm[1]> prompt, type 
                  dns

The following example shows the information that is returned from these two commands:

               system:mm[1]> dns -i1 192.168.70.29 -on
Changes to the network settings will take effect after the next reset of the MM.
system:mm[1]> dns
Enabled
-i1 192.168.70.29
-i2 0.0.0.0
-i3 0.0.0.0
system:mm[1]>
To display the DNS status of a primary management module that supports IPv6, while management module 1 is set as the persistent command environment, at the system:mm[1]> prompt, type 
                  dns

The following example shows the information that is returned from this command:

               system:mm[1]> dns
Enabled
Enabled
-i1 192.168.70.230
-i2 0.0.0.0
-i3 0.0.0.0
-i61 2002:1013::211:25ff:fec3:227d
