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 »

In my previous blog, we looked at how Catalyst switches can be used to assess video application readiness in the network before rolling out a video based collaboration application. In this blog, let us take a look at available tools on the Catalyst switches to monitor and troubleshoot video problems in the network.
As we know, fundamentally, video traffic is different from data traffic. Video traffic is more dynamic and bandwidth intensive and even small changes in delay or loss can cause visible disruptions to user experience. Routinely, IT trouble tickets are opened by users that are faced with degraded video experience. To add to that, interactive video is real time. Any delay in troubleshooting will make IT miss the window to rectify the problem. For a firm with many locations and buildings, finding the problem can be complex and time consuming without the right tools.

Be it tax-credits/subsidies in different parts of the world or the recent news of California setting up a carbon trading exchange – no week passes by without the mention of “the importance of saving energy” or “reducing greenhouse gases”. Yet, with the explosion of technology and IP-connected devices; IT consumes over 25% of energy in a commercial building or office.
So why am I writing about this in a Cisco blog and what has this got to do with networking?

The Global Certification Team (GCT) is pleased to announce the Cisco Catalyst 4900M on IOS version 15.1(1)SG or later has received USGv6 Certification from University of New Hampshire – Interoperability Laboratory. The UNH-IOL uses this collaborative testing model to distribute the cost of performing trusted, third-party testing and validation. USGv6 testing covers 27 categories of USGv6 NPD tests. You can find the listing for Conformance testing v1.2 (12424) at the UNH Interoperability Lab. Additionally, the 4900M has also achieved Ready Logo certification. the details can be found at https://www.ipv6ready.org/db/index.php/public/logo/02-C-000841/.
The Catalyst 4900M provides an ideal solution for space constrained deployments that require high performance wire speed services, high availability, and the modular flexibility of deploying Gigabit Ethernet and 10 Gigabit Ethernet, all in a small 2RU form factor. You can find more information on the Cat4900M on Cisco.com
