Layer 2 and layer 3 switching makes a fun topic for a lot of IT professionals. I often see interesting discussions about this subject. A more practical question from many of you, however, is how to choose a Cisco IOS Software feature license to meet your specific needs. Here I will take a look at 4 common Cisco IOS Software feature licenses for Cisco Catalyst 2K and 3K switches. A quick disclaimer before I go any further: This post is for information-sharing purposes only. It does not represent or replace any Cisco documentation. Product information can change very quickly and usage of this post is solely at readers’ own risk.

International IT services provider Sycor was redesigning the networks for one customer who had 4500 employees spread across 80 branches in addition to a headquarters and many telecommuting and mobile workers. One issue they were addressing was that this customer was having problems with one of their web-based applications. This specific app was used by just one person at each branch, but was important to the customer’s business. So Sycor engineers tuned both the app’s website as well as the central database with which it communicated.
The solution they were considering was a dedicated data terminal at each branch to work separately but in parallel with the existing network deployments. And then the customer started having problems with more applications at more branches. Something had to be done.

I was driving home the other day when I heard a radio report on densely populated California cities. What’s interesting was a mention of a small California city that is ranked as the nation’s fourth most dense urbanized area. I guess that a lot of people don’t know Delano, a central valley city with a population density of 5,483 people per square mile. It’s surprisingly more dense than the New York-Newark, N.J. metropolitan area which is ranked the 5th.
Many people with many devices in a densely populated area can pose a challenge to WiFi networks. I was talking to a Cisco customer in the New York City area a few days ago. He said that deploying WiFi was not as straightforward as it used to be. There are many RF interferences near his office and many new SSIDs that he never saw before.

“In basketball – as in life – true joy comes from being fully present in each and every moment,” says former LA Lakers coach Phil Jackson, and sports fans couldn’t agree more. Today’s followers of the NBA are more present and informed, every minute of every game, than ever before.
In general, the NBA’s outreach, including its websites, mobile apps, TV, and radio broadcasting, saw dramatic increases in activity over the last year.. In 2011, about 75 petabytes of video was posted. Not surprisingly, NBA.com is now the #3 sports site on the web for video streams. Read More »

Routers are the link to the outside world for retail stores, bank branches, manufacturing plants, small offices, and more. Without them we couldn’t buy our groceries with credit cards, get the banking services we expect, or even do our daily work at our own jobs. As our world becomes more and more connected, the number of use cases for routers continues to grow … as do requirements for performance, security, and availability. At Cisco we are privileged to see the latest and greatest of these unusual deployments, so please read on for three interesting cases that made my head turn, and maybe will turn yours as well.
1. Speeding cameras in Scandinavia
If you’ve ever visited Norway, you know they’re serious about traffic control. Not only must every vehicle entering Oslo pay a toll, currently 26 kroner, but they also have to be very careful not to speed. Today Cisco and TDC have teamed up to connect 700 traffic enforcement cameras run by the Norwegian Public Roads Administration. Read More »
