How Cisco’s Multigigabit Technology can increase network speeds

If you remember, in a previous Switch IT Up blog post I referenced Wireless AC and Wave 2 — some of the things that we could expect and some of the problems we could run up against. Things like having enough bandwidth to our APs to support a 6.8 gig connection.So, what can be done about that?Well, in 2015, Cisco introduced its Catalyst Multigigabit Technology, along with a new group of products, that address that issue and allow users to get more than just that 1 gig speed that most people have in their closets or in their infrastructure. How can users leverage that and still use their preexisting infrastructure rather than having to rip everything out and replace it?To read this article in full, please click here

The King is dead?! Heck, no!

It’s been about a year and a half since I asked the question in this blog, “Is the Cisco 6500 Series invincible?” I believe enough time has passed and that I should revisit that question — especially since people in the industry have been talking, tweeting and writing about the demise of the venerable Catalyst 6500 chassis family for years. But don’t worry, the King is not dead because Cisco is having none of that! + Also on Network World: 4 resources to find free Cisco skills and certification labs + Aside from being a major revenue stream for Cisco, the 6500 chassis family remains a solid platform that the company has made extensible by creating the Catalyst 6800 family. To read this article in full or to leave a comment, please click here

Is the Cisco 6500 Series invincible?

The Cisco 6500 Series has proven itself time and time again to be a mainstay in the networking industry. Cisco has done a commendable job with continued enhancements to ensure that the industry’s golden child maintains relevance. If this is the case, why do IT professionals still fear its supposedly impending obsolescence and feel pressure to upgrade to newer models? Let’s just say rumors of its demise are greatly exaggerated.As the industry moves toward 10/40Gig and higher, the need for bandwidth and port density only increases. Software-defined networking (SDN), while certainly worthy of consideration, may not be the best option for all organizations just yet. However, the need for high-speed switching connectivity and robust services remains a concern for the here and now. Enter: The Cisco 6500 Series.To read this article in full or to leave a comment, please click here

Are wearables worth the cybersecurity risk in the enterprise?

The Internet of Things and wearable technology are becoming more integrated into our everyday lives. If you haven't already, now is the time to begin planning for their security implications in the enterprise. According to research firm IHS Technology, more than 200 million wearables will be in use by 2018. That's 200 million more chances of a security issue within your organization. If that number doesn't startle you, Gartner further predicts that 30% of these devices will be invisible to the eye. Devices like smart contact lenses and smart jewelry will be making their way into your workplace. Will you be ready to keep them secure even if you can't see them?To read this article in full or to leave a comment, please click here

Bigger, better, faster: What does Wave 2 of 802.11ac have in store?

"Bigger, better, faster" is a mantra with which many of us are now familiar. Even if it isn't something we have printed on a t-shirt, it can be how we strive to live without often realizing it. Improvement is a part of life. You don't have to look hard to see examples of certain things that have already realized their great potential for improvement. But what about things we take for granted, like wireless?  Wireless is all around us, but it's something we take for granted. Sometimes it’s harder to find a business or public location without Wi-Fi than it is to find one with it. So can wireless actually advance? Whether it's in the boardroom or the living room, we have expectations of buttery-smooth audio and video. As the number of wireless devices grows at a profound rate, how can we shore up the wireless network to provide service to all that’s connected? Wireless AC may be the light at the end of the tunnel. With Wave 1 speeds of 1.3Gbps (your mileage may vary) we're offered a chance to handle the larger amount of requests constantly bombarding our access points (APs). Still, the struggle in dense environments Continue reading
