DESCRIPTION
You can use the dns component to manage configurations by server grouping, in this case, DNS servers.
EXAMPLES
modify dns name-servers add { 192.168.10.20 192.168.10.22 }
Adds DNS name servers with the IP addresses, 192.168.10.20 and 192.168.10.22, to the BIG-IP system.
modify dns search add { siterequest.com store.siterequest.com london.siterequest.com }
Adds the host names, siterequest.com, store.siterequest.com, and london.siterequest.com, to the DNS
search configuration for the BIG-IP system.
Note: When DNS searches for the host, siterequest, which is not a fully qualified domain name, it uses
the IP address of the first match, in this case, siterequest.com.
show running-config dns
Displays the running configuration of the dns component.
OPTIONS
description
User defined description.
include
Warning: Do not use this option without assistance from the F5 Technical Support team. The system does
not validate the commands issued using the include option. If you use this option incorrectly, you put
the functionality of the system at risk.
name-servers
Configures a group of DNS name servers for the BIG-IP system.
number-of-dots
Configures the number of dots needed in a name before an initial absolute query will be made.
search
Configures a list of domain names in a specific order. DNS uses that order when searching for host names
that are not fully qualified. You can use this option to delete domain names in the list.
