Dynamic IP address assignment configuration example
Network requirements
As shown in Figure 17 , the DHCP server (Switch A) assigns IP addresses to clients on subnet 10.1.1.0/24,
which is subnetted into 10.1.1.0/25 and 10.1.1.128/25.
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.
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
