Not real sure about the VNXe3200, but on the VNX and Unity arrays each ethernet port can support up to 8 virtual IP addresses (I think it's higher than 8 on the Unity).
With iSCSI you want to be sure to segregate the different IP ranges - you could use subnet masking or separate VLAN. Also, be sure to use an Enterprise Class switch for iSCSI and not have other traffic.
Thanks! We were told by EMC support that it should work utilizing the multiple iSCSI interfaces/IPs on the same VLAN residing on the same physical port. So we tried it. Thankfully the VNXe was smart enough to tell us "No, you can't do that" when we tried to apply the settings. So we have done as you suggested, and more in line with best practices, and created a second VLAN for the additional iSCSI interfaces on that physical port.
