Wireshark · Ethereal-users: [Ethereal-users] double tagged ethernet frames

["network engineer" <networkeng@xxxxxxxxxxxxx>]

Hi

I am currently trying to capture frames using ethereal.  the frames I am 
sending have two VLAN tags.  which are followed up by a pppoe header.  If I 
use a single vlan tag I can see the frames but if I use two headers I cannot 
see the frames.

My ethereal is connected to a cisco switch whose port is configured as a 
span port.
