Hello Folks!
Device here is supposed to be a pure managed layer 2 switch for gigabit traffic using one trunk link and access ports connected to vlans, but the device is leaking traffic between vlans and trunk or both.
We urgently need help get it sorted out, we have another tread here, what we have done and so on, we tried all, eithe rthe device does not pass traffic at all or fully locks up so a power cycle is needed or it start leaking:

Here is a tcpdump, this traffic on a fully different vlan100 seen on the access ports of vlan200, I dont know what to do:
