SG200 26 - functioning like a hub? ll traffic visible
Thomas is spot on this one. Firmware versions 18.104.22.168 and below have a MAC table bug that causes multicast traffic to appear after 49 days of uptime unless rebooted. The dynamic MAC table stops purging old entries and learning new ones. Release 22.214.171.124 is stable and excellent and is what you should load for now.
