In a previous blog post, I demonstrated the Fabric Attach capability in my lab. Now, let’s explore the Auto-Sense capability. I previously explained what Auto-Sense is: essentially, it allows a switch port to be configured automatically based on the connected devices. On Fabric Engine, Auto-Sense is enabled by default: The Auto-Sense capability is straightforward and… Read More »Network deployments: Past and Present vol. 5
In a previous blog post, I elaborated on the general rules about fabric, how it works, and the protocols used. We already know that services like VLANs inside the fabric are propagated automatically, with no configuration needed within the fabric. Services should only be created at the edge of the fabric—this can be done manually… Read More »Network deployments: Past and Present vol. 3
This “self-forming” network is based on Extreme Networks gear. The complete solution is called Extreme Automated Campus and consists of several key components: Core Components of the Solution The foundation of this solution is the switches running Fabric Engine/VOSS, which can communicate using standard protocols as well as Fabric protocols. Fabric uses only two protocols:… Read More »Network deployments: Past and Present vol. 2
I have been working in the networking field for more than 13 years. Most of my deployments involve a lot of manual configurations. A lot of things had to be configured manually like VLANs, stacking, LACP, STP, some routing, and more. How does it look right now? What kind of changes have been made, and… Read More »Network deployments: Past and Present – part 1
Automation out of the box, available directly on the firewall – Dynamic User Group and Dynamic Address Group. What it is about? Basically, using Palo Alto Networks firewall features, you can automatically add ip addresses or users to dynamic groups and enforce some actions, like blocking or allowing access to some resources. What are practical… Read More »Palo Alto Networks DUG/DAG
