Comment # 3 on bug 8425 from gaohui0208

I.e., if you use the capture filter "udp port 5246", it captures traffic to
port 5246, but does not capture traffic from port 5246?

----- yes

If you don't use the capture filter, do the packets from port 5246 have VLAN
headers?
----- It dose not have vlan tags.

In the attachments,I show two ways to filter packets.
The first way shaw in picture01 used filter rule " udp.port==5246" .It can
capture both direction streams for me,for instance the file
"udp.port==5246(picture01)";
But the second way shaw in picture02 used filter rule "udp port 5246" in other
position ,it dose not work like it should be which described in help guider.

Because I want to capture for many hours continuely,the first way will save all
the streams mirror to this port which result in the packets captured using the
first way will reach many GByte.
The second way only save the packets fit the filter rule,however ,it only
capture traffic to port 5246 too.
