service dns forwarding system

set service dns forwarding system
delete service dns forwarding system
show service dns forwarding
Command Mode
Configuration mode.
Configuration Statement

}
}
}
Parameters
None
Default
None.
Usage Guidelines
Use this command to direct the system to forward DNS requests to name servers statically configured using the system name-server command.
By default, the DNS forwarding service forwards DNS requests to a pool of name servers comprised of the statically configured name servers plus those of which it was notified using DHCP. This command is used to override the defaults: when this command is issued, DNS requests are forwarded to statically configured name servers.
