DHCP relay feature can't be enabled on Private vlan

[identit255]

Hello,

I am trying to implement the private vlan feature to my company network (btw I use two sg350X in stack). There are several vlans that all obtain their ip addresses using DHCP relay from Windows server which acts as DHCP server.

Everything works fine except for enabling DHCP relay. As I tried to enable it, I got this message: Private Vlan Primary Enable prevents executing DHCP Relay feature.

And my question is if there is any way how to solve this problem without changing or adding any DHCP server?

Best regards,

Ok, I already solve it. There is no need for DHCP relay + I have realized that SG350X doesn't support promiscuous trunk feature, so usage of private-vlan is pointless.

Solution: Application of protected-port feature which works perfectly.
