It's a very Cisco like CLI with a range of "carrier" technologies including MPLS, RSVP, LDP implemented. We have found a couple of limitations with FRR, but still quite acceptable once tested. We've also done a fair bit of interop testing with Juniper and Cisco and are still running it in our labs on some S6000s and have had no major issues. It also has a rudimentary HQOS implementation that we haven't really drilled into yet.</div><div><br></div><div>The buffer discussion is something that we keep going back to with Dell.

<p class="MsoNormal" style="background:white">I’ve been impressed with the zero touch deployment part of it but still learning/playing with it at the moment. Though it doesn’t seem quite yet ideal in the enterprise access space, there’s some missing features
that I do like such as the various L2 security options but then again it’s definitely more Data Centre focused than enterprise access, though that may change in the future…<u></u><u></u></p>
<p class="MsoNormal" style="background:white">

<p class="MsoNormal" style="background:white">I’d also give a +1 to Ben, why pay so much for simple routing/L3 switching? In 3-5 years with some maturity I can’t see how you could ever justify the $bigvendor prices for some deployments or at least some devices
within the network. Looking at doing 40/100G and we can see its definitely looking like a good option even now.<u></u><u></u></p>

<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">I'm interested to see if ON is making its way down to the edge (1Gbps PoE/PoE+) or if it's mainly being used at the distribution / core layers or at the service provider level where there's little
end device connectivity and it's more about moving the packets around.<u></u><u></u></span></p>
