I am using DUMPCAP to create a "Ring Buffer" of 4000 capture files.
This works fine.
Dumpcap -i 4 -f "udp port 500 or udp portrange 2000-6000" -b files:4000 -b
filesize:250000 -b duration:900 -w "w:\Captures\Files.cap"
I recently enabled the capturing of VLAN Tag Information as documented in
http://wiki.wireshark.org/CaptureSetup/VLAN
Wireshark correctly captures and displays the Packets with their VLAN .1q Tags.
The DUMPCAP capture files are now Empty.
If I turn off the capture of VLAN .1q Tags by the NIC card, DUMPCAP resumes
collecting packets albeit without the VLAN .1q Tags.
I am assuming this is a bug or am I doing something wrong?
A quick solution would be most appreciated.
Thanx,
John
