To find the percentage of A-MSDU packets in a wireless packet trace using wireshark, which filter should I use from those mentioned below? A-MDSU packets : wlan_aggregate.a_mdsu.subframe ..... filter 1 filter 1 shows there are 0% A-MDSU packets in the trace, whereas filter 2 shows there are 3.5% A-MSDU packets in the same trace.What is the difference between A-MDSU and A-MSDU and which filter is the correct filter to obtain the A-MSDU packets? Also, how to obtain A-MPDU packets in the trace? Is the filter mentioned below correct? asked 02 Nov '16, 06:51  Harshada Kelkar edited 02 Nov '16, 11:47 |
One Answer:
Have you seen this question: I am embarrassed I don't know what an A-MDSU is. Can you provide some context? Maybe I never read that part of the 802.11 specification. I think you want your option 2: wlan.qos.amsdupresent To obtain A-MPDU packets, try sniffing on an an 802.11ac network - that should do. I am no expert as far as A-MPDU, but my experience is that not all drivers will populate that field, but that doesn't mean you won't obtain them. The filter might be described as how to present them in Wireshark if that field is populated. answered 02 Nov '16, 14:35  Bob Jones |
The filter 1 mentions aggregate.a_mdsu so was confused about what a-mdsu is or what that filter does.
However thanks for the help on a-msdu and a-mpdu filters. This does answer my question. Thanks.
