COMMAND

DESCRIPTION

ip dns server zone-forwarder

Sets a domain zone forwarder record that specifies a fully

{<1..32>appendinsert <1..32>}

qualified domain name. You can also use a asterisk (*) if

{domain_zone_name*} {interface

all domain zones are served by the specified DNS

interface_name user-defined

server(s).

domain_zone_name: This is a domain zone, not a host.

ipv4_address [interface {interface_name

auto}]}

For example, zyxel.com.tw is the domain zone for the

www.zyxel.com.tw fully qualified domain name. So

 

whenever the NXC receives needs to resolve a

 

zyxel.com.tw domain name, it can send a query to the

 

recorded name server IP address.

 

interface_name: This is the interface through which

 

the ISP provides a DNS server. The interface should be

 

activated and set to be a DHCP client.

 

auto: any interface that the NXC uses to send DNS

 

queries to a DNS server according to the routing rule.

ip dns server zone-forwarder move <1..32>

Changes the index number of a zone forwarder record.

to <1..32>

 

no ip dns server zone-forwarder <1..4>

Removes the specified zone forwarder record.

43.4.1 DNS Server Commands Example

This example configures the AP to connect to the AP controller (the NXC) by DNS. The following commands:

•Set the AP’s management IP address to 192.168.1.100 and netmask 255.255.255.0

•Sets the AP’s management interface to use VLAN ID 3

•Set the AP’s default gateway IP address to 192.168.1.1

•Add a domain zone forwarder record that specifies a DNS server’s IP address of 10.1.1.1 and uses the bridge 0 interface to send queries to that DNS server

•Set the AP controller’s primary domain name as capwap-server.zyxel.com and secondary domain name as capwap.test.com

Router(config)# capwap ap vlan ip address 192.168.1.100 255.255.255.0 Router(config)# capwap ap vlan vlan-id 3

Router(config)# capwap ap vlan ip gateway 192.168.1.1

Router(config)# ip dns server zone-forwarder append * user-defined 10.1.1.1 interface br0

Router(config)# capwap ap ac-ip capwap-server.zyxel.com capwap.test.com
