If you are a network administrator, then you should know that managing VLANs can be time-consuming and prone to mistakes in large networks with numerous interconnected switches. The VLAN Trunking Protocol (VTP) lets you manage your VLANs from a central…
Explore the important disparities between VLAN Tagged and Untagged approaches. Enhance your understanding of network segmentation and traffic management.
Understanding VLANs (Virtual Local Area Networks) and Private VLANs unlocks advanced network segmentation capabilities, enhancing security, manageability, and performance. In this article, we will discuss the nuts and bolts of VLANs and Private VLANs, their advantages, configuration steps, and how…
Spanning Tree Protocol (STP) remains a critical Layer 2 defense mechanism, even in the age of advanced network fabrics. The STP Root Guard feature is an indispensable tool for preventing rogue switches from becoming the root bridge, thus maintaining network…
While much of the networking world has shifted towards automation and API-driven recovery, there are still situations where understanding fundamental device recovery procedures is critical. This guide, originally published in 2011 and updated in 2021, focuses on the console-based recovery…
Ah, 802.1X authentication – a true veteran in network security, often affectionately (or sometimes exasperatedly) known as Dot1x. I remember configuring my first Dot1x setup way back in the day, and it felt like unlocking a new level of control…
When I first wrote about QinQ tunneling (or IEEE 802.1ad, formally known as Provider Bridging) back in 2011, it was an absolutely foundational technology for service providers. Fast forward to today, and while the network landscape has evolved dramatically with…
Hi guys! I’m back, and as always, it’s great to connect. Life, as a network engineer, often pulls us into deep dives and complex projects, but I always make it a point to share what I learn. Today, we’re revisiting…
