Demystifying the Catalyst: Cisco Context Aware Secure Access (Security Group Tags – SGT) Technology

In this blog, let us take a look at how Catalyst access switches enable and enforce context aware access to IT resources.

Many types of devices, including laptops, smartphones, and tablets, are used by end users to connect to the network wired, wirelessly, and remotely through VPN. With bring your own device (BYOD) access, the devices can be personal or corporate owned. Every enterprise has policies that dictate who can access what applications and databases, when and how. Traditionally, IT manages the policy either by introducing appliances at points in the campus where users connect or by manually configuring all the access switches. Appliances incur additional capital and operational expenses, whereas manual configuration of the switches requires maintenance of every switch. Moreover, the network can carry traffic using Ethernet, IPv4, IPv6, or other technologies, so the configuration must keep up with changes in technology, which leads to higher operational complexity and costs.

More from London – Unified as ONE

BugEyes
I was really impressed with Cisco Live London..for those of you who took the time to shake our hand and say hello…THANK YOU!  You make us feel like geek rock stars!  Good thing the doors are really big at these conferences so my inflated ego could still make it through.  I mentioned our Fundamentals of Converged Wireless and Wireless Access yesterday…but there are a few more detailed videos surrounding this Unified Access Launch that were definitely worth mentioning.
 
First off – Jimmy Ray gets with Muhammad Imam so that he can demonstrate the new controls for QoS on wired or wireless now.  

 
We circle back with another friend, Sachin Gupta, to hear what kind of feedback we are getting back from both geeks and others who have actually already deployed the Catalyst 3850. The pricing is extremely attractive on this…no extra cost even though this is a HUGE revolution from the previous 3700 series. 

 
Perhaps a bit overshadowed, but really should not be overlooked, are the changes we see within the 5760. As the first IOS based Wireless LAN Controller – this new release has identical commands for configuration and management as you do with the 3850. Great example of the ONE Network we speak of now on such a regular basis.

Wired and Wireless Convergence

Lots of big announcements around the new Catalyst 3850 that are very very interesting for how we design networks.  Check out our latest ‘Fundamentals’ to fully appreciate what has been accomplished here!

Thanks for watching as always!

Demystifying the Catalyst: IOS Device Sensors

In this blog, let us take a look at how Catalyst access switches profile the various connected devices and make the information available to various network services.

Many devices like laptops, IP phones, cameras etc. are connected to the network and need to be managed by IT for asset management, device onboarding, switch configuration, policy management & device energy management. Traditionally, IT administrators manually added each device for each service. This consumes unnecessary overhead and is an inefficient use of IT’s time. Read More »
