Comment on Recent Cisco Product Launch by Jason Edelman

Heinz, it will most likely not support FCOE. While I haven’t checked the data sheet, the “F” series linecards were built for high perf L2 environments, “F”COE, “F”abricPath technologies, etc. so they lack support of things like OTV and LISP. The M series are meant for “high performance and full feature” L2/L3 environments.

Cisco has FabricPath, FCOE, LISP, OTV, and MPLS on their main home page for the Nexus 7000, but unfortunately those are the protocols that introduce the most caveats for the 7K!

I cover some of this here although I need to update it with M2 now:

Comment on Some OSS with my Mac, Part 2: Unison by Seb

Hi, I was definitely too tired I got it to work between two Linux boxes in a breeze, but couldn’t figure out why it didn’t work between my Macbook et another Linux box.. “/usr/bin/unison not found” was simply due to the fact I didn’t install on the target Linux box.. I figured it out immediately after having some sleep

Sorry for the annoyance, thanks for this post, it works great now

Thanks for a great post. I’m currently setting up a Linux/win7 lan under a Samba 4 PDCand have used much of the stuff you mention here.

It addresses some of the problems mentioned here and suggests alternatives which may also work with AD/Linux.
Thanks again.

Comment on Setting Up FCoE on a Nexus 5000 by Marc

Hi Scott,
I think on the Nexus 5548 and 5596 Plattform you also need to adjust QoS for FCoE. Because with the enable the feature fcoe, the Nexus will create the new service-policy, but not activate them:

n5548(config)# system qos
n5548(config)# service-policy type qos input fcoe-default-in-policy
n5548(config)# service-policy type network-qos fcoe-default-nq-policy
n5548(config)# service-policy type queuing input fcoe-default-in-policy
n5548(config)# service-policy type queuing output fcoe-default-out-policy

Is that correct?
Thanks a lot

Comment on Technology Short Take #20 by Russell

You’re pretty much spot on with respect to VXLAN in UDP.

I’m not too worried since ethernet doesn’t really care at the end of the day that a frame is delivered either.
