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

     FYI, you do not need enable ip directed broadcast, simply ip
relay address <local gw> under the SVI for the clients to get to ..
int vlan 123
...
  ip dhcp relay address <dhcp server>
  ip dhcp relay address <local subnet broadcast>

 ...

  You get the drill.
