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 VLAN-interface 10 to use DHCP for IP address acquisition.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ip address dhcp-alloc
