• When the forwarding option is set to per-vlan only, the standard (global) DHCP relay service is not 

available. These two types of services are mutually exclusive.

• Using the per-vlan only forwarding option requires you to specify a DHCP server IP address for each 

VLAN that will provide a relay service. The 

 command performs this function 

and at the same time enables relay for the specified VLAN.
