    Big thank you to DeleteMe for sponsoring this video. Use my link https://joindeleteme.com/Bombal to receive a 20% discount or use the QR Code in the video. Also, a Big thanks to Cisco for sponsoring my trip to Cisco Live Vegas 2026. Do you really need Cat 8 Ethernet for your home network in 2026? And what actually happens when you touch the end of a fiber optic cable? We break it all down with hands-on demos. At Cisco Live, I caught up with Jim from Fluke Networks to dive deep into the physical layer of networking. We strip away the marketing hype and look at the real-world performance of both copper and glass. In this video, we cover everything from the crucial safety reasons why you should never look into a fiber cable, to a microscope demonstration showing how a single speck of dirt or finger oil can cause frame errors and take down your SFP modules. We also run a live cable certification test on Cat 6 vs Cat 8 to show you exactly why Cat 6A is all you actually need for your home network, and how pros use an OTDR to find exact breaks in long fiber runs. If you want to build or troubleshoot networks effectively, you need to understand the physical layer. // Jim Davis from Fluke Networks SOCIAL // LinkedIn: / jimdavisflukenetworks Website: https://www.flukenetworks.com/ // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

    #586: Stop zero days without a patch: You need to learn eBPF

    How has AI changed cybersecurity and enterprise networks? In this interview, Michael (General Manager for Cisco's Campus Networking) joins David Bombal to discuss the real-world impact of agentic AI, physical AI, and modern security threats. Discover why the U.S. cybersecurity agency (CISA) reports that the mean time to exploit vulnerabilities has plummeted from 10 months to just 10 hours due to AI systems chaining CVEs together. Learn how autonomous agents are shifting campus and branch environments from traditional north-south traffic to massive east-west flows, creating up to 9x the bandwidth demand. Michael breaks down how network segmentation and "least agency" protect data, how Cisco Live Protect utilizes eBPF inside the Linux kernel to create a compensating shield before a patch is ready, and how line-rate encryption with post-quantum cryptography protects against "harvest now, decrypt later" threats. Finally, find out why network engineering remains an incredibly critical, high-demand career path in 2026.

    #585: Run Full WiFi Networks in your laptop 🤯

    In this episode, David Bombal sits down with Joe and Dalton from Cisco to break down the biggest Cisco Modeling Labs (CML) 2.10 release yet. Joe demos the new open source MCP server (model context protocol) that lets an AI model like Claude build a full CML lab from plain English. Just by asking for three IOL routers with a simple BGP config, the AI looks up the node definitions, invents the IP addresses, builds the topology, chooses eBGP on its own, and even starts the lab and waits for convergence. From there you will see the MCP server spin up a CCNA troubleshooting scenario from the official blueprint, quiz you, review your console history and final config, and hand back an honest evaluation with coaching tips. It can even turn a BGP packet capture into a ladder diagram to explain how the protocol works. Dalton then shows off CML 2.10's new wireless fabric, which runs end to end WiFi simulations with no real radios or physical access points. Watch signal strength change as you drag a client across the canvas, simulate roaming between two APs, add link conditioning to mimic a concrete wall, and run wireless packet capture on the .11 frames. Finally, Joe walks through the upgraded breakout tool that streams live packet captures straight into Wireshark so you can troubleshoot BGP and other protocols in real time. Everything shown works in the free version of CML, making this a must watch for anyone studying for the CCNA or leveling up as a network engineer.

    #584: Will this replace PoE (Power over Ethernet)?

    Big thanks to NTT DATA for sponsoring this video and to Cisco for sponsoring my trip to Cisco Live Vegas. For more information about NTT DATA and Cisco’s partnership, click here https://services.global.ntt/en-us/abo... 1000W touch safe power sounds impossible, but Class 4 Fault Managed Power is changing how we think about power delivery for AI data centers, buildings, networking, and IT infrastructure. In this interview, we look at how Cisco, NTT, and Panduit are approaching the next generation of energy networking systems. Traditional Power over Ethernet is useful for endpoints like access points, cameras, sensors, and phones, but PoE tops out around 100 watts. Fault Managed Power introduces a new class of power delivery that can deliver much higher wattage while intelligently shutting down when it detects a fault, short circuit, or unsafe condition. The conversation explains why this matters now. AI is driving massive demand for data center compute, but that compute requires more power, more cooling, and more efficient infrastructure. The guests explain how AC-to-DC conversion losses add up across multiple power conversion stages, how transmission and distribution losses waste energy before it even reaches the building, and why many legacy data centers spend a large amount of energy on cooling and non-useful power. A key example from the discussion: an average 5 megawatt, air-cooled data center moving to direct liquid cooling and fault managed power could save 75% of its energy cost. That same energy profile could also translate into 2.3x the compute for the same amount of energy. We also discuss touch-safe DC power up to 400V, why DC-to-DC power matters for data centers, how this technology could reduce material and labor complexity, and why network engineers, electricians, data center operators, and IT professionals should understand Class 4 Fault Managed Power. This is not just about sustainability. It is about energy cost, AI infrastructure, safer power delivery, faster deployment, data center efficiency, retrofits, new builds, and the future of networking. // Stephen Kelly SOCIAL // LinkedIn: / stephen-kelly-70737a9 // Denise Lee SOCIAL // LinkedIn: / deniseleeyeh // Website REFERENCE // https://www.nttdata.com/global/en/ // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...
