z
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.
z
After the DHCP client is enabled on an interface, no secondary IP address is configurable for the
interface.
z
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.
