Non-stop Wireless at Johns Hopkins Hospital

June 30, 2014 at 10:42 am PST

Johns Hopkins Medicine is one of the leading health-care providers in the US. The Johns Hopkins University School of Medicine is consistently ranked as one of the top Medical Schools in the US and the Johns Hopkins Hospital is consistently ranked #1 in the US for 21 years in a row! In a previous blog in 2012, we described how the Cisco Wireless LAN controller 7.5 release enables wireless networks to recover with no client re-authentication in the event of a primarily controller failure. In this blog, I will share more details about unified access deployment at the Johns Hopkins Hospital with particular focus on the High Availability design.

Patients are the focus at Johns Hopkins Hospital. Johns Hopkins uses state-of-the-art technology in their hospitals to ensure that patients get the latest advances from surgical tools, radiologic imaging suites with the best diagnostic capabilities to something as humane as sound-absorbing private rooms for each patient.

Catalyst Virtual Switching System and Instant Access (VSS – IA) Lab at Cisco Live US

March 31, 2014 at 6:00 am PST

CLUS14May is fast approaching.  Many people at Cisco, myself included, are making a lot of preparations for Cisco Live US which is May 18 -- 22, 2014 in San Francisco. This is a special year when Cisco Live returns to San Francisco. You might be wondering what’s special, and here’s a quick tip.  It happens only every five years, when it’s a major Cisco anniversary year.  Last time it happened, it was 2009 when Cisco celebrated its 25th anniversary.  Over 10,000 people attended Cisco Live US that year. This year is Cisco’s 30th anniversary. The attendance is expected to be more than doubled. Here’re a few reasons that explain the rapid growth, based on 2013 the Cisco Live surveyed attendee feedback:

  • 99% believe that Cisco Live was a good investment of their time
  • 98% advised they gained valuable knowledge at the event that can be implemented by their company

Every year, new content and topics are being added so that you can keep up with technology evolutions and progress. I want to bring your attention to an exciting new hands-on, instructor-led training session: LTRCRS-2004 Catalyst Virtual Switching System -- Instant Access (VSS -- IA) Lab. It was first offered at Cisco Live Milan in January this year. It was a full house event – many people were put on the wait list because they did not register early enough. Read More »

Virtual Switching: Fundamentals of VSS

December 14, 2011 at 6:22 am PST

Cisco’s been doing virtualization in various forms on the network side for quite a long time. One incredibly powerful feature that I think is still amazingly under utilized is the Cisco VSS or Virtual Switching System.

The ability to make two 6500′s look like a single switch so that you can have your cake and eat it too.  Its the epitome of giving us the redundancy and availability we need while simultaneously allowing us to use the extra capacity that could normally sit unused. Easier management and configuration make this a no-brainer that more network managers should consider as ‘required’ in their design. Check out our ‘Fundamentals of VSS‘ to get yourself started.

Even more after the jump…

Jimmy Ray talks Catalyst Quad Sup Today

Early Mobility

Networking is a lot like life. For example; remember your first stereo and how great it sounded out of the box?   Oh yeah! Tunes jamming and you added +5 to your cool points. But after a few weeks you find yourself looking at other models with “new features”.

Now remember the first Virtual Switching System? A prized center piece of any network design for sure. Then as time passed we wondered; “If it could only have quad Supervisor support”.
