Configuring DHCP client

The DHCP client configuration is supported only on VLAN interfaces.
When multiple VLAN interfaces with the same MAC address use DHCP for IP address acquisition
through a relay agent, the DHCP server cannot be a Windows Server 2000 or Windows Server 2003.

Introduction to DHCP client

With DHCP client enabled, an interface uses DHCP to obtain configuration parameters such as an IP
address from the DHCP server.

Enabling the DHCP client on an interface

To enable the DHCP client on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the DHCP client on the
interface.
An interface can be configured to acquire an IP address in multiple ways. The latest configuration
overwrites the previous one.
Secondary IP addresses cannot be configured on an interface that is enabled with the DHCP client.
If the IP address that interface A obtains from the DHCP server is on the same network segment as the IP
address of interface B, interface A neither uses the IP address nor requests any IP address from the DHCP
server, unless the IP address of interface B is manually deleted and interface A is brought up again by
first executing the shutdown command and then the undo shutdown command or the DHCP client is
re-enabled on interface A by executing the undo ip address dhcp-alloc command and then the ip
address dhcp-alloc command.
