Create Virtual Host - Fex

Hi all,

I have a quick question. I'm looking to do testing to a host sitting behind a fex (not too familiar with fex's). Instead of connecting an actual workstation to the fex in order to get an IP, is there any way I can simulate this, by statically assigning a port with an IP on the fex so it arps and is pingable from devices upstream of the fex (ie, core fws/routers)?

Thanks
