III. Configuration procedure
# Enter system view.
<H3C> system-view
# Enable DHCP.
[H3C] dhcp enable
# Create DHCP server group 1 and configure an IP address of 202.38.1.2 for it.
[H3C] dhcp-server 1 ip 202.38.1.2
# Map VLAN-interface2 to DHCP server group 1.
[H3C] interface Vlan-interface 2
[H3C-Vlan-interface2] dhcp-server 1
# Configure an IP address for VLAN-interface2. The IP address of the interface should
be on the same network segment with the DHCP clients.
[H3C-Vlan-interface2] ip address 10.110.1.1 255.255.0.0
Note:
You need to perform corresponding configurations on the DHCP server to enable the
DHCP clients to obtain IP addresses from the DHCP server. The DHCP server
configurations vary with different DHCP server devices, so the configurations are
omitted.
