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.
