Demystifying the Catalyst: IOS Device Sensors

In this blog, let us take a look at how Catalyst access switches profile the various connected devices and make the information available to various network services.

Many devices like laptops, IP phones, cameras etc. are connected to the network and need to be managed by IT for asset management, device onboarding, switch configuration, policy management & device energy management. Traditionally, IT administrators manually added each device for each service. This consumes unnecessary overhead and is an inefficient use of IT’s time. Read More »

Five Cool Router Tricks with onePK

Network Management is dull.  No excuses.  Monitoring and interacting with the devices that move data from one location to another is a thankless undertaking that most of us building networks leave to an afterthought.  Part of that is the complexity associated with managing networks.  There are at least a dozen common methods for interacting with devices in the network including SNMP, CLI, AAA, Syslog, Netflow, and fancy XML/HTTP interfaces.  So much variety breeds complexity so we tend to set our goals pretty low for interactivity with the network.

What if we had one common mechanism for interacting with the network?  Different devices running different software would all speak a common language to the applications managing and monitoring them.  Now what if that language was something the programmers writing those applications understood implicitly like an API library they could compile directly into their program?  That would make interacting with the network as simple as making a procedure call within the application.  That’s exactly what onePK – or the “one Platform Kit” – accomplishes.

The Optimized Secure Network for Cisco VXI

Today, Cisco announced the new release of the Cisco VXI Smart Solution. Part of the announcement is, of course, enhancements in our Borderless Networks architecture to enable our customers to deploy a secure, reliable, and fast virtual desktop infrastructure.

Cisco Live 2012 Short Take: Techtorials, FCoE, and Customers

June 11, 2012 at 10:24 am PST

I’m here at Cisco Live 2012 in San Diego, and coming off of a high of being able to talk to about 60 CCIE networking rock stars about the next generation Data Center.

In case you aren’t familiar, a Techtorial is an 8-hour continuous spray from the firehose (yes, 8 hours!), on top of the normal Cisco Live fare, that goes into the ultra deep technical weeds. These guys are the ones who are planning, designing, and implementing the data centers that we at Cisco only talk about. Truly stellar group of people who know what they’re talking about.

Our session (I was one of 5 speakers during the day) was a non-stop barrage of some of the most technical networking material you can imagine. We covered everything from Hadoop to VPCs to FabricPath to QoS to VM-FEX, and of course storage.

More and more often, questions from the networking teams are looking at storage requirements as they are planning to accommodate consolidated IO. Not just FCoE, but also iSCSI, NAS, and even Hadoop environments, and they need to know what could come and bite them when they weren’t looking.

When I asked how many of them were already having conversations with the storage teams about converging the networks, about 90% of them raised their hands. As a result, we got into the nitties and the gritties about ingress and egress buffering, COS Virtual Lanes, and QoS bandwidth allocations. Like I said, deep stuff.

As I’ve said before, in my world I have a rather skewed perspective. Since I live, eat, breathe, drink storage -- particularly FCoE -- I see the adoption at all levels in the data center.

And now you can too. I’m going to be giving specific examples of customer deployments at the Expo World of Solutions in Intel’s booth today (Monday, June 11) at 5 p.m., and again in NetApp’s booth on Wednesday, June 13, at 3:00 p.m.

Of course, you can come here it straight from the customer’s mouth, at “Voice of the Customer: FCoE”, where Bart Falzarano, Chief Information Security Officer from Walz Group, will be talking about how his company has deployed FCoE with great success. That session is WoS5030, at the Cisco Main Theatre on Tuesday, June 12 at 12:15 p.m.

These sessions are short -- only 10-15 minutes, so it may not be a good idea to dawdle.

Networking 101 – New Playlists

April 27, 2012 at 9:20 am PST

TechWiseTV Playlist

We updated our little corner of the Cisco YouTube page with some new playlist categories.  Now its easy to find my favorite quick hits -- Networking 101.

Couple of great new videos have been up here recently as @jimmyray_purser rolls ‘em out!

Networking 101: What is an ASIC?

Is a custom application specific integrated circuit (ASIC) really a big deal in networking devices? Jimmy Ray Purser walks us through the difference between custom and full custom ASIC designs. Watch an overview of the steps involved in ASIC design. Learn the the difference between “programmable” ASICs and how to determine the difference between various ASIC models.

Networking 101: Quality of Service

How well do you know QoS? We all throw the term around but are we all truly comfortable with it? Jimmy Ray breaks it down at the packet level and shares the one rule you must never forget.

Networking 101: Switch Latency

Understanding how switch performance is measured can make the difference with application performance. The terminology of switch latency in various switching methods and the methodology to obtain the most accurate latency measurements make it easy to play games with the numbers. Watch this episode of Networking 101 with Jimmy Ray from TechWiseTV and arm yourself with knowledge.
