undo dns-server { ip-address1 [ ip-address2 [ ip-address3 [ ip-address4 [ ip-address5 [ ip-address6 [ ip-address7 [ ip-address8 ] ] ] ] ] ] ] | all }

Usage Guidelines

Usage Scenario

Before a host accesses the Internet, the DNS server needs to be used to resolve a domain name to an IP address. To allow a DHCP client to properly access the Internet, run the dns-server command to configure the IP address of a DHCP server so that the DHCP server can send DNS server addresses to DHCP clients through Option 6.

Precautions

A maximum of eight NetBIOS server addresses can be specified for each address pool.

If DNS server addresses have been configured in an address pool, running the dns-server command adds new DNS server addresses but does not delete the configured ones. To delete the configured ones, run the undo dns-server command.

An earlier configured ip-address has a higher priority. The IP address with the highest priority is used as the primary address, and the other seven IP addresses are used as secondary addresses.

Example

# Set DNS server addresses to 1.1.1.1 and 2.2.2.2 for an address pool named huawei.

<HUAWEI> system-view
[~HUAWEI] ip pool huawei server
[~HUAWEI-ip-pool-huawei] dns-server 1.1.1.1 2.2.2.2
