: Specifies the MAC address of an interface using

Description
Use the
ip address dhcp-alloc
command to configure an interface to use DHCP for IP address
acquisition.
Use the
undo ip address dhcp-alloc
command to cancel an interface from using DHCP.
By default, an interface does not use DHCP for IP address acquisition.
Note that:
z
If no parameter is specified, the client uses a character string comprised of the current interface
name and MAC address as its ID for address acquisition.
z
The DHCP client sends a DHCP-RELEASE message for releasing the IP address obtained via
DHCP, if the interface of the client is down, the message cannot be sent.
z
For a sub interface that obtained an IP address via DHCP, using the
shutdown
command on its
primary interface does not make the DHCP client send a DHCP-RELEASE message for releasing
the sub interface’s IP address.
Examples
# Configure VLAN-interface 1 to use DHCP for IP address acquisition.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] ip address dhcp-alloc
