In-reply-to » Spent the last few days debugging network issues at work. I’ve tcpdump’ed and wireshark’ed the shit out of this. 😂 It’s not very helpful. I’d need to gain insight into the decision making of the switch itself. Why does it drop certain packets? That’s almost impossible to find out (unless it happens to be included in the switch’s logs, which it usually isn’t).

Like said, it’s usually some kind of misconfiguration. Hence you begin to dump the entire switch config into a file and then run diff against the config of a working switch. 🤣 Sometimes this approach works, sometimes it doesn’t …

We recently changed from Cisco to MikroTik switches. At least those switches offer some kind of basic API, which means we can configure them via our config management – instead of using the switch’s web UI or SSH, like some cave men. That should make our life much easier.

Honestly, all the switches I’ve seen so far were total crap. So far, MikroTik is the best thing. Maybe there are actually good switches out there, but they probably cost a ton of money, and we can’t afford that.
