802.1q packet monitoring

I am in a troubleshooting situation and I need some insight about tracing 802.1q packets.

I mirrored the tagged port and ran a wire shark trace but I cant see the 802.1q tag in the packets.

Does anybody have a good way of doing this?

Any help is appreciated!!

Hello,

My intel nic removes the .1q tag. A registry key solves this problem.
