Parameters
group-id: DHCP server group number in the range of 0 to 19.
ip ip-address: DHCP server IP address.
Usage guidelines
The IP address of a DHCP server and the IP address of the DHCP relay agent's interface that connects the
DHCP client cannot be in the same network segment. Otherwise, the client may fail to obtain an IP
address.
If a server group has been correlated to multiple interfaces, you need to cancel these correlations before
removing the server group.
