Configuring your network from Excel

September 26, 2015June 30, 2016 by erjosito

What is the best way to configure a network? There are probably a lot of different opinions out there. Some will say there is nothing like CLI. Others will prefer GUIs. And in this last point people will not agree on what is the best GUI: this one is too complex, this one has too … Continue reading Configuring your network from Excel

What should network config look like? (or the self-documenting network)

August 5, 2015June 30, 2016 by erjosito

This is a question I have thinking about lately, after a customer asked me whether in Cisco ACI you can copy and paste config like in any other Cisco router or switch. Every network admin knows how to do a “show running-config”, copy a fragment of the config into a notepad, change it, and paste … Continue reading What should network config look like?

MAC authentication in Cisco ACI (or how to get the features you need)

June 3, 2015June 30, 2016 by erjosito

You might be thinking the same that I did: why the heck do you need MAC authentication in a data center? However, I came across this requirement from a customer recently. For this customer this was really important. Cisco ACI doesn’t offer any form of MAC authentication today. Furthermore, unfortunately this requirement is not very … Continue reading MAC authentication in Cisco ACI

May update on Cisco ACI/N9K news

June 1, 2015June 30, 2016 by erjosito

Biggest hit this month in my opinion was the release of the NXOS version 7.0(3)I1(2) for the Nexus 9000. I had the chance to test this in a real customer environment last week for VXLAN EVPN, and it worked great, specially in the network convergence area. Don’t miss other exciting stuff like Santiago’s videos on … Continue reading May update on Cisco ACI/N9K news

After all the study and lab time, I have gained some experience with NSX for vSphere, and I would like to summarise here some of my thoughts about … Continue reading VCIX-NV in the bag!

Was network management ever so cool?

April 9, 2015June 30, 2016 by erjosito

Admittedly, I am sick. That is at least what most people would say, if I told them that last night I was having fun programming in Python in order to automate a VXLAN environment using an EVPN control plane. Whaaaat??? In my opinion, VXLAN fabrics with EVPN are really cool. Lots of benefits over traditional … Continue reading Was network management ever so cool?
