Dynamic IP address assignment configuration example
Network requirements
As shown in Figure 18, the DHCP server (Switch A) assigns IP addresses to clients on subnet 10.1.1.0/24,
w h i c h i s s u b n e t t e d i n t o 10 .1.1. 0 / 2 5 a n d 10 .1.1.12 8 / 2 5 .
Configure address range 10.1.1.0/25 and configuration parameters in DHCP address pool 1 so the
DHCP server assigns IP addresses in subnet 10.1.1.0/25 with the lease duration of 10 days and 12 hours
and configuration parameters to clients that connect to VLAN-interface 10 of the server.
Configure address range 10.1.1.128/25 and configuration parameters in DHCP address pool 2 so the
DHCP server assigns IP addresses in subnet 10.1.1.128/25 with the lease duration of five days and
configuration parameters to clients that connect to VLAN-interface 20 of the server.

Configuration procedure
1. Specify IP addresses for the VLAN interfaces. (Details not shown.)
2. Configure the DHCP server:
# Enable DHCP.
<SwitchA> system-view
[SwitchA] dhcp enable
# Enable the DHCP server on VLAN-interface 10 and VLAN-interface 20.
[SwitchA] interface vlan-interface 10
[SwitchA-Vlan-interface10] dhcp select server
[SwitchA-Vlan-interface10] quit
[SwitchA] interface vlan-interface 20
[SwitchA-Vlan-interface20] dhcp select server
[SwitchA-Vlan-interface20] quit
# Exclude IP addresses (addresses of the DNS server, WINS server and gateways).
[SwitchA] dhcp server forbidden-ip 10.1.1.2
[SwitchA] dhcp server forbidden-ip 10.1.1.4
[SwitchA] dhcp server forbidden-ip 10.1.1.126
[SwitchA] dhcp server forbidden-ip 10.1.1.254
# Configure DHCP address pool 1 to assign IP addresses and other configuration parameters to
clients in subnet 10.1.1.0/25.
