NLB static entries - which switch stack?

Hi All

I am at a loss for a definitive answer, can anyone help?

I have a virtual environment with a number of VLANs - the web server VLAN is 133 - the Webservers are using Microsoft NLB - I configured everything in accordance with best practice from Microsoft and VMware - however I run my VMs on blades via blade switches 8024-k which have a trunk to edge switches 3048s which then connect to an MPLS via a Cisco router.  Where do I add my static entries?  At the nearest switch to the webservers, or at the edge on the 3048 - does the Cisco then need a static entry for the NLB MAC and IP?

Or is there a way to get multicast to work in place of unicast?

Thanks
