Figure 54   Network diagram for DHCP server interface address pool configuration

 

■

Configure the IP address of VLAN-interface 1 on the DHCP server (Switch A) as 
192.168.0.1/24.

■

The DHCP clients belong to VLAN 1 and dynamically obtain IP addresses 
through DHCP.

■

The DHCP server assigns a fixed IP address of 192.168.0.10/24 from the 
interface address pool to the file server with MAC address 000D-88F7-0001, 
and assigns IP addresses on the network segment 192.168.0.0/24 to other 
clients with the lease duration of 10 days. The IP address of the DNS server is 
192.168.0.20/24, and that of the WINS server is 192.168.0.30/24.
