Configuring The Dhcp Client; Enabling The Dhcp Client On An Interface - HP 6125XLG Configuration Manual

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 on VLAN interfaces and management Ethernet 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.

Enabling the DHCP client on an interface

Follow these guidelines when you enable the DHCP client on an interface:
On some device models, 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.

•
When a device starts up with
empty configuration, the
management Ethernet interface
does not use DHCP to obtain
an IP address.
•
When a device starts up with
the factory defaults, the
management Ethernet interface
uses DHCP to obtain an IP
address.

configuration and factory defaults,

Guide.
