if you have the possibility to test with<br>
kernel-2.6.32-504.16.2.el6.x86_64 and<br>
kernel-2.6.32-504.23.4.el6.x86_64 please do it.<br>
<br>
I'm expecting that 2.6.32-504.16.2.el6 is the latest correctly working<br>
kernel. Please tell us if this is your case.<br>
There are clear signs of misbehaviours due to changes in the VLAN code<br>
between the two kernels above.<br>
<br>
Also take a look at <a href="https://bugs.centos.org/view.php?id=9467" rel="noreferrer" target="_blank">https://bugs.centos.org/view.php?id=9467</a> and<br>

P.S. sorry for top posting. I tried to revert this thread but I<br>
