It’s time to move away from SNMP and CLI and use Model-Driven Telemetry
Traditional features such as SNMP, CLI, and Syslog, used for collecting operational statistics from a network, have several restrictions due to the growth of the objects like IoT devices and cloud based applications. SNMP uses the pull model when retrieving data from a switch. This model cannot scale for today’s high-density platforms, and offers very […]
New DevNet Learning Module, “Home Lab: Setting up Your Desktop OS for Network Programmability”
Hey, you networkers out there. (Yes, it’s a little weird – I’m talking to networkers in a blog post at a site where a lot of Developers hang out.) Remember the short struggle when you first learned about Cisco devices? What cable to use to connect to the console? What drivers to add to make […]

Let me just start by saying this…10 minutes before we even started the webinar, the questions started rolling in. The first question, of course, being “Do I need to understand programming to be a network engineer?” Something we’re hearing over and over these days.

With another Cisco Live fading in the rear-view mirror, I find myself reflecting on some of the really interesting events that happened. I’m not talking about the customer […]
The New Network – It’s for Developers!
With Open IOS XE, Cisco is Changing the Game Old-school network engineers probably remember the Cisco 2500-series router. It ran a slow Motorola 68000 CPU, the monolithic IOS operating system,...
MPLS+SDN+NFV World Congress 2017: Where The Rubber Meets The Road
Industry experts, operators and vendors present real use cases and technology demos to demonstrate what works, and what does not, for real deployments in live networks.
