Procedure
1.
Specify an IP address for GigabitEthernet 1/0/1 on the device.
<Device> system-view
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] ip address 10.1.1.2 24
[Device-GigabitEthernet1/0/1] quit
2.
Configure the DHCP server:
# Enable DHCP.
[Device] dhcp enable
# Enable the DHCP server on GigabitEthernet 1/0/1.
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] ip address dhcp select server
[Device-GigabitEthernet1/0/1] quit
# Exclude the gateway address and the AC address from dynamic allocation.
[Device] dhcp server forbidden-ip 10.1.1.1
[Device] dhcp server forbidden-ip 10.1.1.3
# Configure DHCP address pool 0 for dynamic allocation.
[Device] dhcp server ip-pool 0
# Specify the assignable subnet as 10.1.1.0/24 and the address lease duration as ten days.
[Device-dhcp-pool-0] network 10.1.1.0 mask 255.255.255.0
[Device-dhcp-pool-0] expired day 10
# Specify the gateway address as 10.1.1.1 and the DNS server address as 20.1.1.1.
[Device-dhcp-pool-0] gateway-list 10.1.1.1
[Device-dhcp-pool-0] dns-list 20.1.1.1
# Specify the AC address as 10.1.1.3.
[Device-dhcp-pool-0] option 43 hex 80070000010A010103
Verifying the configuration
# Verify that the AP can obtain an IP address and all other network parameters from Device. (Details
not shown.)
# On the DHCP server, display the IP address assigned to the AP.
[Device] display dhcp server ip-in-use
Troubleshooting DHCP server configuration
Failure to obtain a non-conflicting IP address
Symptom
A client's IP address obtained from the DHCP server conflicts with an IP address of another host.
Solution
Another host on the subnet might have the same IP address.
