LLDP_Multicast traffic doesn't flow throgh the EX2200

Hello

In order to communicate Siemens TIA Portal and a S-1200 PLC, i have to connect both to the same swicht, but i can't do that.

The S-1200 is generating LLDP traffic but it can't reach the PC whit Siemens software, the EX2200 is blocking it.

I configure a ge-0/0/12.0 as port mirror and monitor the ingress traffric from the PLC is connected. I can see the LLDP traffic. But it doesn't reach the PC.

I tried turning off the storm control  and doesn't work.

Thanks
