server group and the server group itself will be removed.
By default, no DHCP server is specified for a DHCP server group.
Note that:
The IP address of any DHCP server and any interface's IP address of the DHCP
■
relay agent cannot be in the same network segment. Otherwise, the client may
fail to obtain an IP address.

not work. The interface still maintains the previous correlation.
