Hi Michael,
if you have the possibility to test with
kernel-2.6.32-504.16.2.el6.x86_64 and
kernel-2.6.32-504.23.4.el6.x86_64 please do it.

I'm expecting that 2.6.32-504.16.2.el6 is the latest correctly working
kernel. Please tell us if this is your case.
There are clear signs of misbehaviours due to changes in the VLAN code
between the two kernels above.

Also take a look at https://bugs.centos.org/view.php?id=9467 and
https://bugzilla.redhat.com/show_bug.cgi?id=1263561 .

Best regards,
Giorgio.

P.S. sorry for top posting. I tried to revert this thread but I
couldn't do it in an effective way :(
