I am connecting to and monitoring a port on a managed VLAN switch from a Windows Vista machine.

Is there any way to capture the VLAN tags? I presume this may depend on the Ethernet nic and driver. Is there a device/driver that I need to get to support this?

I don’t actually know if the monitoring port delivers the VLAN tags of the packets it is monitoring. The switch is a ProCurve 2600-8-PWR. Anybody know?

I do know that Wireshark can parse these. I used to capture vlan tags when I was watching a VLAN being bridged across 802.11 with WDC.

Take a look at:
