[f-nsp] Microsoft NLB in Hyper-V VMs on SX

[Raja Subramanian]

Dear All,

I am running two Win2k8 Hyper-V servers connected to an SX800 chassis.
 The guest VMs on these two Hyper-V hosts are running Windows NLB
clustering for active/active load balancing.

Problem is that the SX800 is forwarding all client traffic to only one
NLB instance, the other VM is not receiving any client traffic.  I
have tried both unicast and multicast NLB deployment options without
success.  If I run the NLB servers on physical hosts connected to the
same SX800 ports, active/active load balancing works correctly.  It's
only when deployed on Hyper-V that I'm facing this NLB issue.

Does anyone have a working setup with active/active NLB on Hyper-V
deployed on SX gear?

Thanks for any inputs!
