15 Minutes, Puppet and a Screwdriver

Clock

Last week the delegates at Networking Field Day 5 met with Cisco, and we had a great set of presentations and discussions throughout the day. None however equaled the discussion on “Openflow vs Cisco onePK” at the end of the day for the sheer volume of uncompromisingly black and white opinions that were expressed in order to score points in that argument.

The problem for me is that at some point, there’s a danger that taking the hyperbole too far* could cause your argument to actually sound like debating trickery rather than a reasoned position. And so it was for me yesterday listening to the argument that Cisco should offer a basic switch that just supports OpenFlow, rather than wasting time developing an offering supporting onePK. The parallel given was that people tend to buy switches with way more features than they need (or too high a software feature set), so it is better to offer something minimal that is more appropriate.

Decoding the New Infrastructure – NFD5 Redux

NFD5

Networking Field Day 5 (NFD5) drew to a close yesterday, and I have found myself sitting in a plane at around 32000 feet musing somewhat on the fact that my trip home has just been redirected via Chicago rather than Las Vegas (Viva Chicago!), but mostly reflecting on the week’s activities. If you aren’t sure what I’m talking about, read my recent post about the Networking Field Days.

What struck me more than anything was not just that the vendors presenting to NFD5 each delivered a very clear message, but that most of them delivered the same message.

When BGP Aggregates Go Badder

Aggregate!

First, please accept my apologies for the terrible grammar in the title, but really, what better name could I use for a post that is the sequel to “When BGP Aggregates Go Bad“?

Having learned one critical lesson about the redistribution of locally-originated aggregates (described in that last post), I saw an issue recently that could potentially be present in quite a few networks, and the network owners may be totally unaware of it until it’s too late.

NAM-NX1 – The First Nexus 7000 Service Module of Many?

Cisco NAM-NX1At the Cisco Live 2013 even in London this January, Cisco gave attendees a sneak peak of the about-to-be-announced Network Analysis Module (NAM) for, amazingly enough, the Nexus 7000 series switches. In fact, it is the first – and currently only – service module for the Nexus 7k.

So now that the NAM has been officially announced, I wanted to take a quick look at the product itself, and maybe look at what it may herald for the Nexus 7k lineup.

Cisco Live 2013 – Are You a Keynote Virgin?

Cisco Live 2013

It’s ok, you can be honest with me. Do you attend the Keynote sessions at Cisco Live?

Not everybody loves the Keynote sessions, but since the schedule is set up so that the three main Keynotes are the only activity going on at that time, it’s usually worth attending – they’re usually packed with good information, and I find it much more convincing to be spoken to directly rather than read a press release about what’s going on.

Cisco Live 2013 in Orlando is following a similar pattern to previous years, and having three main keynotes:
