Specifying DNS servers for DHCP clients
To access hosts on the Internet through domain names, a DHCP client must contact a DNS server to
resolve names. You can specify up to eight DNS servers in a DHCP address pool.
To specify DNS servers in a DHCP address pool:
Step
1.
Enter system view.
2.
Enter DHCP address pool view.
3.
Specify DNS servers.
Specifying WINS servers and NetBIOS node type for DHCP
clients
A Microsoft DHCP client using NetBIOS protocol must contact a WINS server for name resolution.
You can specify up to eight WINS servers for such clients in a DHCP address pool.
In addition, you must specify one of the following NetBIOS node types to approach name resolution:
•
b (broadcast)-node—A b-node client sends the destination name in a broadcast message.
The destination returns its IP address to the client after receiving the message.
•
p (peer-to-peer)-node—A p-node client sends the destination name in a unicast message to
the WINS server. The WINS server returns the destination IP address.
•
m (mixed)-node—An m-node client broadcasts the destination name. If it receives no
response, it unicasts the destination name to the WINS server to get the destination IP address.
•
h (hybrid)-node—An h-node client unicasts the destination name to the WINS server. If it
receives no response, it broadcasts the destination name to get the destination IP address.
To configure WINS servers and NetBIOS node type in a DHCP address pool:
Step
1.
Enter system view.
2.
Enter DHCP address pool
view.
3.
Specify WINS servers.
4.
Specify the NetBIOS node
type.
Specifying BIMS server for DHCP clients
Perform this task to provide the BIMS server IP address, port number, and shared key for the clients.
The DHCP clients contact the BIMS server to get configuration files and perform software upgrade
and backup.
To configure the BIMS server IP address, port number, and shared key in the DHCP address pool:
Command
system-view
dhcp server ip-pool pool-name
dns-list ip-address&<1-8>
Command
system-view
dhcp server ip-pool pool-name
nbns-list ip-address&<1-8>
netbios-type { b-node | h-node |
m-node | p-node }
