Configuring the DHCP client

With DHCP client enabled, an interface uses DHCP to obtain configuration parameters from the DHCP
server, for example, an IP address.
The DHCP client configuration is supported only on Layer 3 Ethernet interfaces (or subinterfaces), VLAN
interfaces, Layer 3 aggregate interfaces, and management Ethernet interfaces.

Enabling the DHCP client on an interface

Follow these guidelines when you enable the DHCP client on an interface:
If the number of IP address request failures reaches the system-defined amount, the DHCP
•
client-enabled interface uses a default IP address.
An interface can be configured to acquire an IP address in multiple ways. The new configuration
•
overwrites the old.
Secondary IP addresses cannot be configured on an interface that is enabled with the DHCP client.
•
• If the interface obtains an IP address on the same segment as another interface on the device, the
interface does not use the assigned address. Instead, it requests a new IP address from the DHCP
server.
To enable the DHCP client on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Configure an interface to use
DHCP for IP address
acquisition.

Configuring a DHCP client ID for an interface

A DHCP client ID is added to the DHCP option 61. A DHCP server can specify IP addresses for clients
based on the DHCP client ID.
Make sure the IDs for different DHCP clients are unique.
To configure a DHCP client ID for an interface:
Step
1. Enter system view.
2. Enter interface view.
