Yes, of couse.

- have some TCP traffic sniffed.
- Select Statistics->IO_Graph
- Click the the area 'Y Axis' in Unit and select Advanced
- type in Filter tcp&&ip.len
- type in calc ip.len
- select Sum
- Click on Graph.

The point which I do not get is why do I have to write
tcp&&ip.len when I want to filter all TCP Segments. All
of them have the ip.len field, except you do not run TCP
on top of IP, which i have not seen.

Best regards
Michael

to provide two filters, one is a substring of the other.

Sure, but can you tell me the sequence of actions where this is needed?

Use "tcp&&ip.len" as the filter and use "ip.len" as the field.

the field variable must be part of the filter string

Ummm, what exactly does that mean? Is this with Ethereal or Tethereal?

Dear all,

how do I use the IO stat advanced stuff to plot the sum of ip.len for
all
packets containing tcp. I tried to use tcp as a filter and ip.len as
the
field, but this does not work.

Thank you very much for your help.

Best regards
Michael
