All 802.11ac Vendors are the same…Right?

If you are an Enterprise IT Manager, this is a question that you must ask yourself if you are considering deploying 802.11ac for your enterprise wireless network. 802.11ac has some great benefits such as wirelike speed and being able to handle a high concentration of clients. However, there is more to consider when deploying 802.11ac. For instance, how do I handle RF interference now that 802.11ac support 80MHz channels? Will legacy devices such as 802.11g/a/n allow me to achieve the best performance that 802.11ac advertises? How can I ensure that my users get the best wireless performance when they roam across a building? And lastly, as more clients join the network, is my performance going to suffer? These are all valid concerns and are something that Cisco addresses with HDX. HDX is High Density Experience and is part of Cisco’s 802.11ac solution. We just wrapped up a 4 part blog series on HDX where we answer these questions:

-          For Interference Mitigation, we have CleanAir for 80MHz Channels

-          Getting the best performance out of your network even with legacy clients, we  have ClientLink 3.0 Read More »

Cisco Small Business Online Device Emulators

August 15, 2013 at 4:27 pm PST

How do you get a feel for things? Perhaps a little research online, a review or two, maybe a referral from a friend or co-worker. But big purchases, such as a new car may require more; more information.  So you go to take a test drive. Well, we have something similar to a test drive.

As you may know, it is not often you get a chance to check out how an IT device’s graphical user interface (GUI) looks and feels. Sure you might see a couple of static screen capture and be able to point how the navigation menu is laid out. But beyond that, it is not until the device is purchased and in the installation process, that the real user experience is realized. It’s hard to get a grasp on on the level of complexity for set-up and deployment, let alone configure a VLAN or set-up a secure VPN.

Well, we have offered something better. Our team has delivered a set of device emulators, including switches, access points and routers. You can actually navigate through the actual menus, see how the wizards look and work, and truly get a sense of how easy the small business products are to configure, install, deploy and manage.

Here is what the emulators/GUI’s look like:

Small Business Online Device Emulators

You will notice that all of the small business product user interfaces share the same look and feel, as well as similar general navigation principles. With our Small Business product line, we truly take to heart the need for a great user experience and are always looking to make our products easier to use.

Please, leave us a comment or suggestion good, bad or otherwise to help us improve our products.

802.11ac: Is Your Network Infrastructure Ready for Next-Gen Wi-Fi Traffic?

The next generation of Wi-Fi, 802.11ac couples the freedom of wireless with the speed of gigabit Ethernet. This also translates in additional load on the backbone of the network, which has to deliver at least 3 times the capacity of the current gold standard, the 802.11n based network.

Cisco launched the Unified Access architecture  to scale linearly with the increased load on the network with 60 Gbps Wi-Fi throughput on the Cisco 5760 Wireless LAN Controller and 40 Gbps Wi-Fi throughput on the Catalyst 3850 Series Switch with a built-in wireless controller.  Both these platforms are based on the Cisco Unified Access Data Plane (UADP) programmable ASIC, which provides high performance and scale, common open APIs, and enables consistent QoS policies for both wired and wireless networks.

Aruba recently launched the 7240 series controllers with a throughput of up to 40Gbps claimed, with the same goal of delivering 802.11ac capable performance across the network. This controller is based on a generic network processor and not a purpose built ASIC like the Cisco controller.

Miercom performed a third-party evaluation to benchmark these products  using  IMIX (Internet Mix) packet traffic and test QoS traffic for high priority application.  IMIX is traffic pattern consisting of a preset mixture of small, medium and large frame sizes used to emulate real-world traffic scenarios in a testing environment. We wanted to give you a sneak peek at some of the results.

Performance

Cisco 5760 is six times faster and Catalyst 3850 is 4 times faster as compared to Aruba 7240

miercom1

The Cisco 5760, 3850 and the Aruba 7240 were tested for throughput using RFC 2544 and IMIX Traffic.  The Cisco 5760 and 3850 performed extremely well by achieving 50 Gbps and 37 Gbps, whereas Aruba 7240 fell short by just achieving 8 Gbps, which is 20% of its advertised throughput.

Momentum is growing for the Cisco ISR-AX!

It has been a couple of weeks since its launch and we are seeing lots of interest in the Cisco ISR-AX!  I have been hearing from customers, partners and folks  worldwide about how they are using the new ISR-AX platforms now and get a router, VPN, firewall, intrusion prevention, cloud/web security, AVC (NBAR2, QoS, NetFlow, Media Monitoring, PfR) and WAN optimization (WAAS) all in one box for less than the cost of just an alternative WAN Optimization appliance.  For WAN optimization with WAAS that is less than $1 per WAN optimized connection with ISR-AX!

Anyway, I’ve gotten lots of questions since the launch, so I grouped them and wanted to share the top 4: Read More »

What Cisco Partners Need to Know About the New Release of VXI

Cisco partners have told us multiple times that the Virtualization Experience Infrastructure (VXI) continues to be the Gold standard for Virtual Desktop Infrastructure (VDI). We appreciate your input. At the same time, we know there’s more we can do to help you.

So we’re happy to share with you that a new release of VXI comes out today. What does this mean for you?

Let’s have a look first at what’s new, how this meets your customers’ demands, and then how that applies to your business.

First, key to the announcement is an opportunity for partners to now offer Cisco’s collaborative services, enabled by Cisco Jabber. This means customers can select the work style most suited to their needs: mobile, fixed, and now virtual. Cisco Jabber for virtual environments is enabled by Cisco Virtualization Experience Media Engine (VXME), a new software component that delivers high-definition video and voice communications to be integrated as part of a virtual desktop session.

Why is this important for your customers? Read More »
