SD-WAN Troubleshooting & CLI Command Reference

[Sam Caprio]

Hello everyone,

I'm new to SD-WAN and recently finished reading the official Design, Deploy, and Secure SD-WAN book. While it provides a solid understanding of the concepts, I noticed it doesn't go into much detail on troubleshooting or cover the complete set of every usefull SD-WAN CLI commands.

Can anyone recommend a good guide or resource that covers SD-WAN troubleshooting, packet captures, and the commonly used CLI commands for diagnosing and resolving issues?

Beyond the design book, the Cisco SD-WAN Command Reference and the Cisco Community/DevNet troubleshooting docs are much stronger on CLI — commands like show sdwan bfd sessions, show sdwan control connections, and show sdwan omp peers come up constantly in real diagnostics. For packet captures, check monitor capture on cEdge or tcpdump on vEdge, depending on which OS you're running. Cisco Live sessions (search "BRKRST" SD-WAN talks) are also great for real failure scenarios and packet-level walkthroughs.
