Configuring DHCP client

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

Configuration restrictions

The DHCP client configuration is supported only on Layer 3 Ethernet interfaces (or subinterfaces),
•
VLAN interfaces, and Layer 3 aggregate interfaces.
You cannot configure an interface of an aggregation group as a DHCP client.
•
• 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.

Enabling the DHCP client on an interface

Follow these guidelines when you enable DHCP client on an 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.
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.
