Cisco IOS Software Licenses: What’s What for Layer 2 and Layer 3 Switching – Part 2

May 21, 2012 at 2:44 pm PST

In my previous post, I discussed 4 common Cisco IOS Software feature licenses for Cisco Catalyst 2K and 3K switches. I specifically concentrated on LAN Lite and LAN Base licenses for layer 2 networks. Today I’ll take a closer look at layer 3, IP Base and IP Services licenses. I’ll point out again that this post is not intended to represent or replace any Cisco documentation. Product information can change very quickly and use of this post is solely at the readers’ own risk.

For those of you who have used Cisco switches for a long time, do you remember the Cisco Catalyst 5500 switches with a Route Switch Module (RSM)? That was how layer 2 and layer 3 were put together within a single chassis – in a kludgy way. Those days are long gone. The Cisco Catalyst switches today feature powerful and integrated layer 3 capabilities. Layer 3 switching and routing are so close that they spark lots of fun discussions. Here, I’ll concentrate on the layer 3 switching capabilities of the Cisco Catalyst 3560-X and Catalyst 3750-X switches.

Cisco UPOE and EnergyWise at Interop Las Vegas 2012

May 17, 2012 at 10:46 am PST

Cisco UPOE is a hit, ramping up to more than 1 million ports annualized run rate since its introduction last year. Read what IT World Canada and CRN have to say about the opportunities afforded by Cisco UPOE.

Beyond powering a wide range of devices with 60W PoE power, Cisco UPOE really shines when it is combined with Cisco EnergyWise. EnergyWise allows you to monitor and control the power consumption of devices connected to the switches. The combined EnergyWise and UPOE demo at Interop showed how you can use the network to turn devices on and off remotely to save power when the devices are not being used. In the following video, Rich Zavala, Technical Marketing Engineer, explains to Jimmy Ray from TechWise TV how he is powering a multitude of devices over Ethernet including LED lights and personal telepresence units, and how Cisco EnergyWise automates energy management for IT and non-IT equipment connected to the switches.

Top Five Considerations for Enabling IPv6 Support on Your Application Delivery Controller

May 14, 2012 at 11:35 am PST

As we approach the much talked about World IPv6 Launch on June 6th, 2012 it is important to help as many as possible do what is needed to prepare their own Internet Edge to not only participate in the launch but also to ensure business continuity regardless of which IP version is used.  Start now so you don’t have to rush your deployment at the end.

There are important first steps to take before you ever type the first command or click the first check box on a product.  Important stuff like a gap analysis on what you can and cannot support as well as what your provider supports IPv6-wise, what your address plan will look like and other considerations. Luckily Cisco has either written a document or a blog on many of these topics. Recent blogs include:

Given that we are just shy of a month away from World IPv6 Launch, I wanted to blog on the top considerations for enabling IPv6 support on one of the most important components of any Internet Edge design, the Application Delivery Controller (ADC) or more commonly known as a Server Load Balancer (SLB).

The Cloud Networking Landscape – Survey Results From over 1300 Networkers [INFOGRAPHIC]

 The 2012 Cisco Global Cloud Networking Survey, which includes participants from more than 1,300 IT decision makers in 13 countries, was commissioned to measure the adoption of cloud services by IT professionals globally, while examining potential challenges to their cloud migrations.  Below, we take a deeper look at some of the positive, negative, and strange aspects to come out of the survey.

On the positive side, 73% of respondents felt they have enough information to begin their private or public cloud deployments. This leaves 27% who claim to feel more knowledgeable about how to play Angry Birds than the steps needed to migrate their company to the cloud. While Angry Birds is a fun game to play, this wan’t the strangest result from this research. Read More »
