SG300 DHCP server on each VLAN

Hello there, 

 

I am trying to setup 2 VLAN on my SG300 with a DHCP server on each one. I've created 2 ip pools (192.168.10.0 and 192.168.20.0) and VLAN 1 / VLAN 2

The problem is:

When i configure VLAN 1 to work on pool 1, it works ok. Every device i connect to VLAN 1 gets an ip from the switch, but if i after configure VLAN 2 to work on pool 2, VLAN 1 "loses" the configuration and i cant get an ip address. 

 

I tried changing the switch to Layer 3 Mode but i cant see any difference. 

 

Any idea?

Sorry but i think that i don't understand you or maybe i explained myself badly. 

 

I need both DHCP servers to be inside the switch. The ip helper is used when the DHCP server is outside the switch, right?

First of all why you need 2 DHCP Server? ( since both going to be the same box, you will not able to achieve high availability)

 

instead you can setup 1 DCHP Server with 2 scopes and use helper-address with options, make sense?
