The advice from that old network guy saved me 3 hours today
I was swapping a switch in a server room over on Market Street and the VLAN config wasn't taking. My coworker kept insisting I needed to reboot the whole stack. But I remembered what this retired Cisco guy told me at a shop last year - he said check the native VLAN mismatch first. Sure enough that was the whole problem, took 2 minutes to fix. Anyone else run into old timer tips that actually work better than the official docs?

Learn from the old guys for sure" - yeah, but only if you know which ones to trust. The real trick is figuring out who actually worked on the gear versus who just read the same manuals you did. I've met plenty of "veterans" who still think spanning tree is a newfangled gimmick. The best old timer advice I ever got was from a guy who told me to stop trusting SNMP traps and just watch the port lights while I ping. Sounds dumb, but that one trick has caught more bad cables and dying NICs than any monitoring tool ever did. The old school stuff works because it gets you looking at the actual hardware, not just the config window.

Old timer advice is gold. The guy who taught me about STP root bridge placement saved me a full day of troubleshooting once.
