3064 supports it or not – it appears some Nexus gear can, but I couldn’t find anything specific on the 3064.<o:p></o:p></span></p>

<p class="MsoNormal">Hello Fellow Ausnoggers,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm hoping that I can quickly pick the brain of someone more knowledgeable in data centre networking than myself.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">We have a customer in one of our racks in Equinix who has a single network switch, and some servers connected to it. We currently have two connections from our switch to the customer's switch, with LACP for redundancy (and as a side effect,
we get a slight bandwidth boost for 2 x 1Gbps connections, which is a slight bonus).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">We would like to improve this by putting in two network switches on our end, to protect again a single switch failure on our side, but the customer will still have one single network switch.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm pretty sure we can't do LACP with this style of setup - so what would people recommend to achieve redundancy here? Main thing is that the connection needs to auto-failover if a network switch fails, or if one of the uplinks fails.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I have created the attached diagram which illustrates what we are trying to do.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Can anyone please help? I'll owe a beer at the Next AusNOG meetup!<o:p></o:p></p>
