I'm doing some captures an an Interface and Writing it to Files. In this interface I'm receiving two expected Vlans (2010, and 2020)...
But I saw some hosts in the network sending QinQ vlans... I dicovered it whent I did a: tshark -r capture.pcap -Y "vlan.id == 2010"-o 'gui.column.format:"Mac-Source","%uhs","Vlan","%Cus:vlan.id"' Then i saw some packets, with other vlan tags then 2010: xx:xx:xx:13:ed:c0 2010,446 xx:xx:xx:13:ed:c0 2010,446 xx:xx:xx:13:ed:c0 2010,1037 xx:xx:xx:13:ed:c0 2010,1037
And I want to create an expression to display-filter that only shows the packets with more then one Vlan Tags.
I shure that only packest with first Vlan tags with 2010 and 2020 will come, but I cant precise any vlan ID that will appear on second vlan tag.
Does anybody have any suggestion?
