Re: similar to ip helper-address on Nexus SVI ?

Well, the functionality is actually different.
It uses a VACL to catch the traffic and forward it.

Are you by any chance using a local DHCP server and then falling back to a
DHCP server on another segment?
The VACL will catch this and you will need to specify the local DHCP server
in the relay command also.
