Conclusion

Troubleshooting Cisco ACI can be complex, but having the right commands at your fingertips makes it much easier. This guide covers key commands for APIC controllers, leaf switches, and spine switches, helping you check endpoints, VLANs, interfaces, routing, VPCs, and overlays.

For leaf switches, you’ll find commands to track endpoints, check VLAN mappings, monitor interfaces, and troubleshoot routing protocols like OSPF, EIGRP, and BGP. On the spine switches, key commands help verify COOP protocol data and detect dampened endpoints.

By using these commands regularly, you can quickly diagnose issues, keep your ACI fabric running smoothly, and avoid unnecessary downtime. Whether you’re dealing with a misconfigured VLAN or an unreachable endpoint, this cheat sheet will save you time and effort! 🚀
