DS DHCP Snooping not blocking leases

[yannick]

Hi All,

I have enabled DS on a port where I have a DHCP server but it is still sending leases and my laptop is getting its ip addresses over DHCP.

If I enable Iso on both ports, DHCP is no more working. But I need those port to communicated with each other but I want to block the DHCP server
Any idea ?

it is a WS-12-250-AC
