Shoutout to the mystery MAC flooding issue that ate my entire Tuesday

Spent a solid 8 hours last week chasing down intermittent network drops across our office floor. Turns out a rogue access point from a neighboring tenant was flooding our switch with random MAC addresses. The logs just showed 'port security violation' with zero details about the source. Swapped cables, rebooted gear, even replaced a patch panel before I thought to check the RF spectrum. Has anyone else dealt with a neighbor's gear causing this kind of silent chaos in a shared building?

Dang, that sounds like a headache! Had a similar thing happen when a crypto mining rig next door kept tripping our power.

Man that's brutal... a rogue AP from another tenant messing with your switching is just dirty pool. Sometimes the simplest fix is the last thing you check.
