Cisco Wireless Networks Connects a Generation

Your mom and dad are on Facebook, your Grandma has a cell phone and your Uncle Oscar reads the morning paper on his tablet. If you haven’t noticed yet, it’s not just young people who are connected to their devices anymore. Erickson Living—one of the United State’s largest operators of continuing-care retirement communities—knows this fact only too well.

“There’s nothing new about the need to remain connected,” said Hans Keller, Vice President, IT Operations, Erickson Living. “It’s just that our residents have moved way past traditional family phone calls. They’re active in social media and part of the new wave of connectivity.”

California Schools Utilizes Cisco Access Points and Switches for Better Learning

It’s no secret that public schools have needs that often go unfunded. So when a school district gets the opportunity to earmark funds for technology enhancements, they need to make sure they get the best.



After years of school budgets cuts, the Manteca Unified School District (MUSD) received a one-time gift from the state legislature to reinvest funds back in their schools. The district made the decision to create a “Going Digital” initiative. This initiative was created to completely overhaul the district’s entire network infrastructure.  This infrastructure overhaul wasn’t child’s play as MUSD serves more than 32,500 students spread out over 32 campuses in California’s Central Valley. The district was given a time limit to complete the project—it had to be finished in nine months.

Using Cisco products such as Cisco Aironet 3700 Series Access Points, Cisco Catalyst 6500 and 2960-X Series switches, the school district completely updated their network. Thanks to devices supporting 802.11ac next-generation wireless standards, students are able to take advantage of their new wireless network. This means students can compete against classmates in digital quiz games or learn how to use a 3D printer. But this technology doesn’t just make the lives of students easier. By using management solution data, the district can locate lost devices, view usage statistics and learn about individual user’s connections from a central location. It can also quickly fix problem areas by giving the MUSD IT staff the ability to spot issues and fix them quickly.  The network is scalable so that new technologies—such as a physical security system—can be added in the future.

To flow or not to flow?

NetApp’s newest storage operating system, clustered Data ONTAP (cDOT), leverages a backend of Cisco Nexus switches for it’s cluster interconnect network.

When configuring the switch/cluster ports for use with cDOT, the best practice is to turn flow control off as per TR-4182. In fact, that happens to be the recommendation for normal data ports as well. Why is that? Before we get into that, let’s cover the basics…

What is flow control?

Flow control is a mechanism used to help manage the rate of data transfer between two devices. This is done to help prevent a source evice from overwhelming a destination device by sending more packets than the destination can handle. These scenarios can occur if a source device is faster than the destination device (CPU, RAM, NIC, etc). This can also happen if the source is intentionally trying to flood the destination via a malicious Denial of Service (DoS) attack.

Flow control can be enacted for send or receive packets, or both. It can be hardware or software based. It can occur at multiple layers of the OSI model

For a real world analogy to flow control, think of how dams work. A dam will be installed to control the flow of water on a river, usually to create lakes or reservoirs. Dams can be used to adjust the water flow to prevent flooding, depending on rainfall. Network flow control does pretty much the same thing – it prevents data floods. Read More »
