Furthermore, unfortunately this requirement is not very … Continue reading MAC authentication in Cisco ACI
(or how to get the features you need)
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

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?

I recently got from F5 colleagues the idea, why not working on an automation use case showing the integration between ACI and F5. One use case they see often in their customer basis is autoscaling of Web farms: some system is looking at the load on the servers, and if that load grows over a … Continue reading The network is *not* in my way
Some time ago I published a video in youtube describing a way to put together multiple workload types here: https://www.youtube.com/watch?v=kmBnpl5XwnM. It describes how to coordinate the configuration of the physical network (Cisco ACI) and a virtual network (vSphere vSwitch, OVS with Linux containers), in two cases: where the virtual network configuration is driven from the ACI … Continue reading Cisco ACI and Linux containers
