Last fall, I attended the Tech Field Day NFD8 event, and one of the presenting companies was Nuage Networks. This was actually the second time I’d seen Nuage present at an NFD event, the first one being NFD6 a year earlier. Upon my return from NFD8, I did a short write-up of each presenting sponsor for my coworkers at H.A. Storage Systems to keep them informed. The following is my recap of Nuage Networks after their presentation in which I explain why I think Nuage is really on-target with their SDN solution and is definitely a solution to keep an eye on.
Working for a data center-focused reseller/integrator like H.A. Storage Systems, I spend my fair share of time in various data center environments. I have, for years, elected to use some sort of hearing protection when in these facilities. I have constantly been amazed, though, at how few other workers in data centers do the same.
Earlier this September, I attended the Tech Field Day Networking Field Day 8 event. Over the course of three days, we saw presentations from many very interesting vendors including a mix of startups and established market leaders. One trend that really stuck out to me more this time around than at any previous NFD event was a nearly ubiquitous emphasis on data center network fabric management. In other words, truly managing an entire data center network (or at least a sub-block of it) as a single unit.
Cisco Live 2014 is right around the corner! It’s almost time to start packing. The other day, Keith Miller (@packetologist), a first-time Cisco Live attendee, asked me on Twitter:
@BobMcCouch Since you are the king of being prepared, what is your travel pack consisting of to CLUS?

I have a bit of a reputation among some of my consulting clients as being ready for just about anything. Normally, that means my laptop bag weighs about 50 lbs. But for Cisco Live, I choose to travel light. I’ve seen people in the airport on the way to, and from, the event with a LOT of stuff. Sure, some folks are presenters or carrying company stuff but for the rest, you probably just have too much stuff.
In my last EEM post I provided a simple means to change an IP address and default route of a Cisco router using a script that makes the change without requiring interactive user input. This is helpful if you are remotely changing a device’s WAN/Internet IP and waiting for some on-site hands to move a cable over to a new ISP or WAN SP connection. That first script, however, would make the change and then exit. What would happen if the new Internet connection had a problem, or the on-site help couldn’t move the cable for some reason? Proper testing and preparation should help you avoid most of those issues but you just never know.
