SG500X-48 forwards traffic on all ports

Hello to everybody!

I have a problem with my SG500 which I do not understand: It is forwarding all traffic to all ports. So for

me it looks like it behaves like a hub.

 

Can anybody please help me?

 

I have a SG500X-48 with firmware version 1.2.0.97 which is in "standalone" mode with this configuration:

switch8d3012#sh run
voice vlan oui-table add 0001e3 Siemens_AG_phone________
voice vlan oui-table add 00036b Cisco_phone_____________
voice vlan oui-table add 00096e Avaya___________________
voice vlan oui-table add 000fe2 H3C_Aolynk______________
voice vlan oui-table add 0060b9 Philips_and_NEC_AG_phone
