Are you sure that the monitor port of the switch you use is configured
to forward tagged frames?

Hi, all.
I have a WinXP SP2 machine with a NDIS driver installed. Application running
on this machine re-assembles VLAN-tagged Ethernet frames and sends them to a
router via L2 switch.
When I run Ethereal (0.99.0, WinPcap 3.1) on this machine, I can see correct
VLAN-tagged Ethernet frames sent to the destination, but when I monitor
(with Ethereal) the LAN between that machine and L2 switch - the frames do
not include the VLAN-tags. Its seems me strange.
So, my question is - what is source of information for Ethereal on the WinXP
machine ?
Thanks in advance.
