C613-50100-01 REV C Command Reference for x930 Series 793
AlliedWare Plus™ Operating System - Version 5.4.6-1.x
DOMAIN NAME SERVICE (DNS) COMMANDS
IP
NAME-SERVER
ip name-server
Overview This command adds IPv4 or IPv6 DNS server addresses. The DNS client on your
device sends DNS queries to IP addresses in this list when trying to resolve a host
name. Host names cannot be resolved until you have added at least one server to
this list. A maximum of three name servers can be added to this list.
If you are running VRF lite, you can add IPv4 or IPv6 DNS server addresses for either
the global VRF lite instance or for a specific VRF lite instance. Host names cannot
be resolved from within a VRF lite instance until you have added at least one
name-server to that VRF lite instance.
The no variant of this command removes the specified DNS name-server address.
Syntax
ip name-server <ip-addr>
no ip name-server <ip-addr>
Syntax (VRF lite) ip name-server [vrf <name>] <ip-addr>
no ip name-server [vrf <name>] <ip-addr>
Mode Global Configuration
Usage To allow the device to operate as a DNS proxy, your device must have learned
about a DNS name-server to forward requests to. Name-servers can be learned
through the following means:
• Manual configuration, using the ip name-server command
• Learned from DHCP server with Option 6
• Learned over a PPP tunnel if the neighbor advertises the DNS server
This command is used to statically configure a DNS name-server for the device to
use.
For more information about DHCP and DNS, see the IP Feature Overview and
Configuration Guide.
Examples To allow a device to send DNS queries to a DNS server with the IPv4 address
10.10.10.5, use the commands:
awplus# configure terminal
awplus(config)# ip name-server 10.10.10.5
Parameter Description
<ip-addr> The IP address of the DNS server that is being added to the name
server list. The address is entered in the form A.B.C.D for an IPv4
address, or in the form X:X::X:X for an IPv6 address.
