Usage guidelines
When you execute the undo ip address dhcp-alloc command, the interface sends a DHCP-RELEASE
message to release the IP address obtained through DHCP. If the interface is down, the message cannot
be sent out.
For a subinterface that obtained an IP address through DHCP, using the shutdown command on its
primary interface does not make the subinterface send a DHCP-RELEASE message for releasing the
subinterface's IP address.
Examples
# Configure interface Ethernet 1/1 to use DHCP for IP address acquisition.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] ip address dhcp-alloc
