Enable DHCP Relay on Cisco Nexus

From OISecWiki

On normal Cisco IOS routers it's really straight forward, you just do

interface VlanXXX
 ip helper-address DHCP

On Nexus it's a little bit more complicated. You have to enable the feature, enable it globally and then add it on the interface.

feature dhcp
ip dhcp relay
int VlanXXX
 ip dhcp relay address DHCP
