Hi, thanks for the quick Answer, The other cpsw's are also occupied for other uses. I had a meeting with my customer yesterday and we hopefully found another solution using a VLAN-Routing, so we only need the two CPSWs. But because I've the AX88760 here, I try to give more information on this bug next week to get it fixed although we don't need it any more.
