#578: How Cisco Is Using AI to Fix Networks

Cisco is bringing AI agents into network operations with Cisco Cloud Control, AI Canvas, and Agentic Ops. In this demo, David Bombal is joined by DJ Sampath (SVP and General Manager, AI Software and Platform) to look at how Cisco is using AI to simplify complex network troubleshooting, infrastructure management, agent security, and observability. Instead of jumping between multiple dashboards, tools, teams, and tickets, Cisco Cloud Control brings network, security, observability, and infrastructure context into one interface. The demo starts with a simple real-world problem: why can’t a phone connect to the network? From there, Cisco AI Canvas investigates the topology, calls the right agents, checks the wireless environment, moves into the firewall/security domain, and identifies the root cause: a site-to-site VPN tunnel issue caused by missing OSPF route exchange. You will see how Cisco is using MCP servers, topology agents, troubleshooting agents, firewall agents, and purpose-built models to help network engineers understand what is happening across Meraki, Catalyst, Firepower, Intersight, Splunk, Security, and other Cisco platforms. The video also covers the Unified Cisco Fabric app, which connects campus and data center environments with a firewall in between, plus Cisco’s agentic security app for monitoring and controlling AI agents in the enterprise. DJ also shows how Cisco is thinking about token usage, runaway agents, agent observability, Splunk, Galileo, policy enforcement, and secure AI adoption. The interview also covers Cisco’s work with OpenAI and Codex, including how frontier models, purpose-built Cisco models, MCP servers, APIs, Cisco data fabric, and real network data are being used to reduce hallucinations and make AI more useful for infrastructure teams. If you are a network engineer, cybersecurity professional, infrastructure engineer, or someone trying to understand how AI will affect networking, this demo shows where things are going.

#577: My Dream "home lab"

Join me for an exclusive, behind-the-scenes tour of Cisco's purpose-built $20 million AI data center lab in San Jose. AI is revolutionizing the tech industry, but running massive 10,000 GPU clusters can cost up to $175 million a year—and a mere 5% network bottleneck can flush $8 million down the drain. In this video, we break down the hardware, software, and networking topologies required to build, secure, and scale massive AI data centers. I sit down with Cisco engineers to explore scale-up domains with NVIDIA H200 and AMD MI350X servers, scale-out rail-optimized topologies, and the massive Cisco Silicon One G300 ASIC delivering 102.4 Terabits per second with innovative liquid cooling. We also dive into the Ethernet vs. InfiniBand debate for scaling to 100,000 GPUs, the power of Linear Pluggable Optics (LPO) to reduce power draw, and how Cisco used AI to safely refactor 500,000 lines of legacy code. Whether you are building an AI network today or upgrading your engineering skills for the future, this is video can help you learn.

#575: AI attackers are winning. Here is the SECRET to survive.

Are AI attackers winning the cybersecurity war? In this video, I sit down with Daniel Miessler, a 25-year security veteran, to discuss the terrifying reality of AI-driven cyber attacks and the massive advantage hackers have today. But it is not all doom and gloom. Daniel introduces his open-source project, PAI (Personal AI Infrastructure), demonstrating how you can build a customized, local AI assistant to automate your workflow, defend your data, and level up your tech skills. We cover everything from AI agents conducting prompt injection CTFs (like Gandalf) in real-time, to the future of work and why the ultimate goal of many corporations is zero human employees. Whether you are worried about AI replacing your job or you want to learn how to leverage local LLMs, Linux, and agentic AI to become an unstoppable force, this conversation is your blueprint for surviving and thriving in the 2026 tech landscape.
