Network Troubleshooting Guidelines

It all started with an interesting weird MLAG bugs discussion during our last Building Next-Generation Data Center online course. The discussion almost devolved into “when in doubt reload” yammering when Mark Horsfield stepped in saying “while that may be true, make sure to check and collect these things before reloading”.  I loved what he wrote so much that I asked him to turn it into a blog post… and he made it even better by expanding it into generic network troubleshooting guidelines. Enjoy!
