Considering the dhcp ip range you want to allocate to switch 3 is the only valid active dhcp scope being shown, Just attach all dhcp clients to switch3.

However that begs the question how are all the other hosts connecting to the other 4 switches obtaining their ip addressing and where from?

If you like Switch 3 device need to get IP address from "10.10.0.241-250 IP from this range."

I am afraid you could able to get that since all are in VLAN 1, so DHCP is first come first serve basis, until you make them different VLAN,

since it's an unmanaged switch, you need your uplink port to be a different VLAN, but that breaks the chain.

my suggestion is to make them static reservations, if only few IP addresses, Remove the scope IP address by excluding. "10.10.0.241-250"

each entry like below explained :

All switch has static IP already.

All switch has static IP already.

this bit confused here, you have a dump switch, this has IP Address?

are you looking to clients connected to the device should get IP address ? please confirm?

what IP Address each switch has?

all switches have static IP 10.10.0.2-6.

dump switch is unmanaged so it has no IP.it is just connected to the switch3(sg-350).

I have one cabin and one data port but in that cabin, I have 5 pc so I need internet and my LAN network. and that pc changes most of the time.so I can't static binding that.
