Open offices can be harsh environments, you never know what dangers are hidden behind you until the interruption arrives.
Keeping up with the new releases of the various manufacturers is an important part of the job of every network engineer. Usually it is enough to see the videos available online but from time to time it is necessary to take one more step. Cisco has released the new Catalyst 9000 family that integrates with 1/20/2019 12:11:45 PM and ISE to build an SDA network. The Catalyst 9k family, strong of IOS XE, also allows programmability levels not previously possible.
I really enjoy discussing network design and deploy details with colleagues, customers and fellow network engineer. I find these discussions challenging, stimulating. An open, sincere and collaborative discussion gives a chance to better understand the real needs, fears, doubts of other professionals and to validate knowledge, expose gaps and most of all I learn a lot. This is still valid when discussing Data Center design or simpler topics like how to cable switch stacks.
I’ve been working on a data center migration from regular switches to a Cisco ACI fabric in the last couple of months. I can’t say that’s enough to be defined as an ACI expert but I’ll share here what I learned from the experience. The project started with a Network Centric approach for an one-to-one migration from the previous network. After the migration new VRFs are being created in App Centric mode with contracts.
