All,

I noticed that from release ethereal 0.10.0, the protocol 802.1q (virtual LAN) is supported. I tried this out but I do not see any VLAN type (0x8100) nor VLAN tag in the ethernet frame. When using another tracer, I can clearly see the VLAN type and tag being transferred within the VLAN.

My testsetup is as follows :

Lan switch which supports VLANs.
Multiple devices connected exchanging messages with VLAN tags.
Example : laptop with win2000. My VLAN tag is 10.
When starting ethereal and start capturing the packets, I can select my virtual interface of my laptop supporting the VLAN. As I expalined higher, after my MAC addresses, I expect the VLAN type and tag, but ethereal shows directly the packet type (IP: 0x0800).

Did somebody encounter the same problem ?

Regards,
Tom
