You can set DHCP options at the subnet, shared network, host-groups, and hosts level. Options set at
lower levels override those set at higher levels.

• Leased Configuration form: sets the DHCP lease times. This form is used at all DHCP levels.
• Client Configuration form at the DHCP grouping level: sets client address, host-group, and other
settings. Subnets and shared networks use the same form; hosts and host-groups have unique
settings on this form.

This form is used at all DHCP levels.
