In this video, Tony Fortunato demonstrates how to use the popular network analyzer to track DNS problems.
RPA technology promises efficiency and cost savings. Here are some best practices.
My Network Automation in Enterprise Environments blog post generated the expected responses, including:
Some of the environments I am looking at have around 2000-3000 devices and 6-7 vendors for various functions and 15-20 different device platform from those vendors. I am trying to understand what all environments can Ansible scale up to and what would be an ideal environment enterprises should be looking at more enterprise grade automation/orchestration platforms while keeping in mind that platform allows extensibility.
Luckily I didn’t have to write a response – one of the readers did an excellent job:
Read more ...Sometime before midnight Monday (UK local time) a ship dropped its anchor and broke, not one, not two, but three undersea cables serving the island of Jersey in the English Channel. Jersey is part of the Channel Islands along with Guernsey and some smaller islands.

These things happen and that’s not a good thing. The cut was reported on the venerable BBC news website. For the telecom operators in Jersey (JT Global) this wasn’t good news. However looking at the traffic from Cloudflare’s point of view; we can see that while the cable cut removed the direct path from London to Jersey, it was replaced by the backup path from Paris to Jersey. The move was 100% under the control of the BGP routing protocol. It's a relief that there's a fallback for when these unpredictable events happen.
Here's a look at one network on the island.
The red traffic is being served from our London data center (the normal location for all Jersey traffic) and the blue traffic is coming from our Paris data center. The step could well be caused by either a delayed break in one of the cables or the Continue reading
Tom Lantzsch makes the jump in January.
We found it!!!
Have you ever sat at your desk, hoping on a miracle, that somebody somewhere will develop a fully comprehensive application for tracking network information??? I know I have, along with millions of other fellow network professional’s I have to assume. What exactly am I referring to? IP addresses, vlans, VRF’s, Rack Elevations and on and on and on. We all have to keep up with this information, for most it is located in spreadsheets; some in notepads; others try to lock it all away in the vast empty space we call a brain.
So, the stage is set. Yes, there are claims of applications that can keep track of what your CORE router IP address is and what vlan you assigned to one of your customers, or even where in the bloody rack it sits in relation to your other devices. Some can even keep track of which VRF routing table your management lies in along with which physical port it connects to. Going a little further, maybe the application claims to give you a basic map layout to which you can refer to…
BUT, very few paid applications actually combine most of these functions into one and very Continue reading
