We're halfway through 2013 and we have our second new member of the Nexus family of switches for the year: the Nexus 7700. Here are the highlights:
The bufferbloat project has had trouble getting consistent repeatable results from 
other experimenters, due to a variety of factors. This Wiki page at bufferbloat.net attempts to identify the most common omissions and mistakes. There be land mines here. Your data will be garbage if you don’t avoid them!
Note that most of these are traps for people doing network research in general, not just bufferbloat research.
No, this isn’t SDN-related, I mean the soft skills. The interpersonal skills. The skills that will help you get ahead in your career. This is my opinion on the matter, so take it all with a huge grain of salt. The biggest thing that a lot of people forget is that there’s more […]

– The GUI and questions are all electronic, there are no printer workbooks, similar to the CCIE R&S lab test. All rack equipment is accessed thought remote access. San Jose and RTP don’t have any local equipment. Most of the IOS devices are running IOU, IOS-XR and Catalyst are using physical devices.
– Passing rate for SP is a lot higher than CCIE R&S. With the addition of IOS-XR there was a significant drop of CCIE Continue reading

Walking the line […]
