Configuring DHCP Server 691
By default, global address pools and VLAN interface address pools are not
configured with any DHCP client domain name.
If you execute the dhcp server domain-name command multiple times, the
newly configured DHCP client domain name overwrites the existing one.
Configuring DNS Server
Address for DHCP
Clients
When a host uses a domain name to access the Internet, the domain name must
be translated into an IP address. Domain name system (DNS) is responsible for the
translation. Therefore, when a DHCP server assigns an IP address to a DHCP client,
it must also send a DNS server address to the client. At present, you can configure
up to eight DNS server addresses for one DHCP address pool.
Configuring DNS server address for a global DHCP address pool
Perform the following configuration in DHCP address pool view.
Configuring DNS server address for current VLAN interface
Perform the following configuration in VLAN interface view.
Configuring DNS server address for multiple VLAN interfaces
Perform the following configuration in system view.
By default, no DNS server address is configured for global and VLAN interface
address pools.
If you execute the dhcp server dns-list command multiple times, the newly
configured IP addresses overwrite the existing ones.
