The dns-list command configures the DNS server address for the DHCP client.
The undo dns-list command deletes a configured DNS server address.
By default, no DNS server address is configured.

Usage Scenario
This command applies to DHCP servers. If user hosts access hosts on the network by domain names, user hosts need to send DNS requests to the DNS server and resolve the domain name to access for communication. To connect a DHCP client to the network, configure a DHCP server address so that the DHCP server can assign both the specified DNS server address and an IP address to the client. To configure DNS server addresses for an interface address pool, run the dhcp server dns-list command.
Precautions
In the IP address pool view and DHCP Option template view, a device can be configured with a maximum of eight DNS server addresses respectively. The address first assigned to the clients functions as the primary address, and the other seven addresses function as secondary addresses.
