H3C S7500E Series Ethernet Switches Chapter 2 DHCP Server Configuration
2-18
The DHCP server configuration for the two types is the same.
I. Network requirements
z The DHCP server (Switch A) assigns IP address to clients in subnet 10.1.1.0/24,
which is subnetted into 10.1.1.0/25 and 10.1.1.128/25.
z The IP addresses of VLAN-interfaces 1 and 2 on Switch A are 10.1.1.1/25 and
10.1.1.129/25 respectively.
z In the address pool 10.1.1.0/25, the address lease duration is ten days and twelve
hours, domain name suffix aabbcc.com, DNS server address 10.1.1.2, gateway
10.1.1.126, and WINS server 10.1.1.4.
z In the address pool 10.1.1.128/25, the address lease duration is five days, domain
name suffix aabbcc.com, DNS server address 10.1.1.2, and gateway address
10.1.1.254, and there is no WINS server address.
z The domain name and DNS server address on the subnets 10.1.1.0/25 and
10.1.1.128/25 are the same. Therefore, the domain name suffix and DNS server
address can be configured only for the subnet 10.1.1.0/24. The subnet
10.1.1.128/25 can inherit the configuration of the subnet 10.1.1.0/24.
 Note:
In this example, the number of requesting clients connected to VLAN-interface 1 should
be less than 122, and that of clients connected to VLAN-interface 2 less than 124.
