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. This situation can occur when a subinterface obtained an IP address through DHCP, and the shutdown command is executed on its primary interface. The subinterface will fail to send a DHCP-RELEASE message.

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
