have to use a hairpin in order to get the functionality to work.� These

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Here�s something to try:</span></p>

routing, just switching), but the concept remains the same.� If the SX800
isn�t routing, then you�ll create VLAN101, move the physical uplink
from VLAN100 to VLAN101, loop VLANs 100/101, add your static-arp entry to the
loop port in VLAN101.� </span></p>

<p class="MsoNormal"><span>Hello,</span></p>
<div>
<p class="MsoNormal">�</p>
</div>
<div>
<p class="MsoNormal"><span>Thank you for
your valuable suggestions and time.</span></p>
</div>
<div>
<p class="MsoNormal">�</p>
</div>
<div>
<p class="MsoNormal"><span>The client is
having a Windows NLB cluster configured for an application and is terminated to
the Foundry switch. �The Windows cluster is receiving request constantly
on one server and not on other server.</span></p>
</div>
<div>
<p class="MsoNormal">�</p>
</div>
<div>
<p class="MsoNormal"><span>We tried
configuring static MAC address on both the Ethernet ports as suggested by
Foundry guide for Windows NLB setup and followed some guidelines from Cisco
guide also. �Both the guidance were failing to deliver the request on both
the servers.�</span></p>
</div>
<div>
<p class="MsoNormal">�</p>
</div>
<div>
<p class="MsoNormal"><span>The client is
running a Hyper-V on two separate physical servers and each Hyper-V is holding
3 Nos. of virtual machines. �The Windows NLB cluster is configured only
for 1 Virtual machine in each physical server.</span></p>
</div>
<div>
<p class="MsoNormal">�</p>
</div>
<div>
<p class="MsoNormal"><span>The servers
are terminated in the Foundry SX800. �The windows NLB cluster's are
configured to work in Unicast mode and also tested with Multicast mode also.
�On both the testing, we are not getting the results on both the servers.
�The Windows NLB cluster is working perfectly with Cisco switch without
any issue.</span></p>
</div>
<div>
<p class="MsoNormal">�</p>
</div>
<div>
<p class="MsoNormal"><span>The client
tested the Windows NLB cluster configured separately on the physical servers
(test bench) which is connected to the Foundry switch and we get the results as
expected. �But when tested with Windows NLB cluster configured on a
Virtual machine, it fails.</span></p>
</div>

</div>
<div>
<p class="MsoNormal"><span>Do someone
have come across this issue and is there any workaround to resolve the same?</span></p>
