Hello,
there is (serious) bug in SwOS 2.0 and/or CSS106 HW, that renders management IP in tagged interface unusable. For some reason (error in switch programming, I suppose) device returns frames tagged with wrong VID. It (probably) works for VIDs 2-15 (tested 2, 3 and 15) then something gets messed up. For VIDs 16 and 17 I'm getting untagged frames, for VID 906 - returned frames are tagged with 778 and for 908 -- with 780.
I hope it's trivial bug that can be quickly and easily fixed.
Regards,
fb
