after the dhcp port is deleted, the dhcp service is not usable. I can<br>
resume the dhcp service by adding another subnet, but I don't think it is<br>
a good way. Do we need to consider bind dhcp port to another segment when<br>
deleting the existing one?<br>

I can go along with that. Thanks for the clarification.<br>
