Hi,
Dissection is fine. What I was wondering is whether it is possible to
show these individual data chunks as separate frames themselves.
But they are in the same frame. I really prefer not to show them in a way
they have not been on the wire. Basically agreed on the above point. Changing the default behavior may not be good due to all the copied lower layer bytes and resulting increase in the size of capture in case there are 4-5 chunks per packet. But still feel it would be a nice optional feature to have when doing actual offline analysis.
Hence, when i apply display filter , only the chunks with exact matches
should be visible. Is this supported currently?
No. Filtering is based on packets. Not sure how to improve that. We can't
show 'half' of a packet. However, there might be ways to draw your attention to the upper layer packet which matches the filter. Regarding above point, would like to suggest that the packet information being displayed can be restricted to the PDU which actually matches the display filter. E.g out of an SCTP packet carrying 3-4 M3UA chunks, the pinfo of only the chunk matching the filter can be displayed?

Best regards MichaelCurrently , i use the below tool for this purpose: http://frox25.no-ip.org/~mtve/wiki/SctpDechunk.html Regards, Vineeth what problem are you trying to solve? Wireshark supports dissecting theupper layer paylaodfor bundled DATA chunks for ages...
