At some point, I used to think networking—and the science behind it—was really hard.
Even after earning my CCNA, I still struggled with fully understanding some concepts… and honestly, I still do sometimes.

If you’ve ever felt this way, you’re not alone.

One thing that has helped me (and I’ll be sharing more of this going forward) is constant revision and going back to the basics.

I always start by asking a simple question:
How are packets forwarded?

To answer that, you need to think of the OSI model and TCP/IP as the standard framework for network communication.
If packets are forwarded, how exactly does that process work?

Let’s break it down step by step—starting from a Layer 2 and Layer 3 perspective.

From a Layer 2 perspective, it’s about understanding how frames are transmitted and distributed while avoiding collisions.
This takes me from collision detection, to switches, and eventually to multilayer switches (MLS) that help manage collision domains efficiently.

Think about this:
How does a packet move from one host to another within the same segment?
Is the frame tagged or untagged?

Key things to consider at Layer 2 include:
•VLANs and Native VLANs
•Access ports and Trunk ports
•Collision domains
•MAC addresses
•MAC address tables
•Broadcast and Unicast traffic
•ARP (which bridges Layer 2 and Layer 3)

Understanding these concepts makes troubleshooting much easier—like identifying source and destination device ports by examining the MAC address table.
How often do you actually do this in real troubleshooting?

Let’s take it one step at a time before moving fully into Layer 3 packet forwarding.

Quick question for you:
Can you explain a VLAN table format?

⚠️ Windows 11 KB5074109 Update Breaks Systems

Source: https://t.co/2nDfuY2r3h

Microsoft's January 2026 Windows 11 security update KB5074109 has triggered multiple system stability issues, including lockups and black screens, prompting users to uninstall it.

Reports highlight graphics regressions and app failures affecting both consumer and enterprise setups.

KB5074109 targets Windows 11 versions 24H2 (build 26200.7623) and 25H2 (build 26100.7623), delivering over 100 security fixes, including three zero-days, alongside non-security improvements like NPU power optimization.

This should be the 3rd or 4th time that I would be posting this scene.

Though, I always tell my son that I love him. But I believe that in this movie (fences), Denzel was telling his son that he loves him, without necessarily using the word "love".

Very sweet scene.

For those going into Network Engineering:

Note: Ethernet service activation tests like Y.1564 are the real deal because they prove your network delivers what the SLA promises.
