If sFlow samples a TCP packet it is very likely that the
|
|
TCP analysis will flag the packet as having some error with
|
|
the sequence numbers. sFlow only report on a "sample" of
|
|
traffic so many packets will not be reported on. This is
|
|
most obvious if the colorizing rules are on, but will also
|
|
cause confusion if you attempt to filter on
|
|
"tcp.analysis.flags".
|
|
|
|
The following only works to suppress IP/TCP errors, but
|
|
it is a start anyway. Other protocols carried as payloads
|
|
may exhibit similar issues.
|
|
|
|
I think what is really needed is a more general
|
|
"protocol_as_payload" flag. Of course then someone has to
|
|
play whack-a-mole and add code to implement it to any
|
|
protocols that could be carried as a payload. In the case
|
|
of sFlow that pretty much means anything on your network.
