Hi @eveav Thank you for this information. I have 3 SGSW-24040 upgrade their firmware from v1.1b090522 to v1.1b090806. After upgrade web interface and Vlans... us OK but data transfer on all ports was very very low (around 300kbps). I downgrade to old version but still data transfer is very low. Is it possible that hardware was damaged in all 3 switches with simple firmware upgrade? It seems now packets not forwarded by hardware and forwarded by cpu. Please tell your suggestion me I will try everything ! Regards
