4.2 Enabling the DHCP Client on an Interface

Follow these steps to enable the DHCP client on an interface:
Enter system view
Enter interface view
Enable the DHCP client
on the interface
Note:
An interface can be configured to acquire an IP address in multiple ways, but these
ways are exclusive. The latest configuration will overwrite the previous
configuration.
After the DHCP client is enabled on an interface, no secondary IP address is
configurable for the interface.
If the IP address assigned by the DHCP server shares a network segment with the
IP addresses of other interfaces on the device, the DHCP client enabled interface
will not request any IP address of the DHCP server unless the conflicted IP address
is manually deleted and the interface is made UP again by first executing the
shutdown command and then the undo shutdown command or the DHCP client is
enabled on the interface by executing the undo ip address dhcp-alloc and ip
address dhcp-alloc commands in sequence.
