Parameters
groupNo: DHCP server group number. This argument ranges from 0 to 19.
Description
Use the dhcp-server command to map the current VLAN interface to a DHCP server group.
Use the undo dhcp-server command to cancel the mapping.
Note that:
A DHCP server group can correspond to multiple interfaces, while an interface can only be
correlated with one DHCP server group.
If you execute the dhcp-server command repeatedly, the latest configuration will overwrite the
previous one.
Before referencing a DHCP server group, you need to use the dhcp-server groupNo ip
ip-address&<1-8> command to configure the DHCP server group.
