Microsoft NLB multicast not working well with Nexus 5k and 7k..NEED HELP!!!!

Question: Hi all,
We need your expertise to help us clarify the NLB configuration on our 5k or 7k switches. We are in the process of migration our email exchange servers from 2003 to 2010. We are implementing Microsoft NLB (network load balancing) on our CAS servers (Client Access servers). These two server are VM guest machines .Their physical VMware hosts are directly connected to 2k switches on port eth101/1/33-36.
Our exchange consultant insisted us to add the following command into either 5k or 7k to allow NLB multicast traffic passing through to all end users hosts.

here is the command requested by our consultant.

Arp 10.156.2.132 03bf.0a9c.0284 ARPA
Mac-address-table static 03bf.0a9c.0284 Vlan 10 interface Ethernet101/1/33-36

I tried to add the above commands into either 5k and 7k . it bounced back with "unrecognized command error".

Note: Many users out there are experiencing the same issue we are having now.

Below are some links regarding configuring NLB on Cisco switch with Microsoft and VMware:

Question#1
Am I missing anything here that is stopping me from entering these commands?

Question#2:
Since my computer is connected via a static ip address and via Vlan1 port. I am able to ping NBL cluster host Ip address 10.156.2.132 but nobody else who are on other  VLANs (subnets) 101,102,103,104,105 and vlan 50 (wireless subnet).

I am about to add the following command to 5k switch, but want to know if these commands might make it work.

switchport trunk allowed vlan 1,3,5,10-11,15,50,52

interface Ethernet101/1/33
  description Link to ESX # 1
  switchport mode trunk
switchport trunk allowed vlan 1,3,5,10-11,15,50,52

interface Ethernet101/1/34
  description Link to ESX # 1
  switchport mode trunk
switchport trunk allowed vlan 1,3,5,10-11,15,50,52

interface Ethernet101/1/35
  description Link to ESX # 2
  switchport mode trunk
switchport trunk allowed vlan 1,3,5,10-11,15,50,52

interface Ethernet101/1/36
  description Link to ESX # 2
  switchport mode trunk
switchport trunk allowed vlan 1,3,5,10-11,15,50,52

Any help are greatly appreciated.!!!
Thanks,
Danny.
