Hi guys, i'm trying to define VLAN tagging in windows7 for Intel(R) 82566DM Gigabit Network Connection. i tried the "windows xp configuration like: find out the network card brand. open registry editor (start > run > regedit or regedt32 ) find the following location: etc... but didn't work for me in windows7, so Wireshark app don't show VLAN Tagging when "Capture".
there is any different\special settings for windows7?

Are you sure the traffic contains VLAN tags? On most switches you have to configure the spanport to replicate the vlan tags. Depending on the brand and model you need to specify it when configuring the spanport, configure the destination port as a vlan tagging port, etc.

If you are trying to capture the VLAN tags on a Cisco 802.1Q trunk port, then use this syntax:-
monitor session x source interface fa0/y
monitor session x destination interface fa0/z encpssulation dot1q
You may also need a registry edit to prevent the NIC stripping the VLAN header. I have another post ongoing on the same subject. You probably need to add a DWORD like MonitorMode or MonitoModeEnabled (I am not familar with your card, but one of these works for other Intel NICs).
Also look for a "Priority & VLAN" option in the NICs configuration (Advanced tab). Set this to "Priority & VLAN Enabled".

I have a different Intel NIC in my Windows 7 laptop & with the registry edits it works fine. Have you tried searching Intels KnowledgeBase?
