Here are the commands I use constantly when troubleshooting: 1️⃣ show ip interface brief - Quick status of all interfaces 2️⃣ show running-config - See current config (duh!) 3️⃣ show ip route - Where's the traffic going? 4️⃣ show vlan brief - VLAN assignments at a glance 5️⃣ show cdp neighbors - Who's connected to what? Pro Tip: Add "| include [keyword]" to filter output: show run | include hostname Which command do YOU use the most? Drop it below 👇
