DHCP overview
NOTE:
•
After the DHCP client is enabled on an interface, the interface can dynamically obtain an IP address and
other configuration parameters from the DHCP server. This facilitates configuration and centralized
management. For more information about the DHCP client configuration, see "Interface management."
• For more information about DHCP, see H3C WX Series Access Controllers Layer 3 Configuration Guide.
The Dynamic Host Configuration Protocol (DHCP) provides a framework to assign configuration
information to network devices.
DHCP uses the client/server model.
