diameter protocol CCA and CCR

Hello, I would like to find all CCRs/CCAs in a big diameter trace. Usually I use session-id to correlate them one CCA and one CCR. I filtered all CCAs, how can I find all related CCRs? Is it possible to use something like a FOR loop?

Thanks in advance

There is a sample capture attached to 8692: Wireshark combines two diameter messages (RAA & CCR-U) in one

A display filter of diameter.CC-Request-Number seems to show all CCR and CCA.

MATE can be frustrating to work with but was created for stuff like this - WSUG - MATE.

sorry I was not clear in my explanation:

I can find all CCRequests: (diameter.flags.request == 1) && (diameter.cmd.code == 272)

I can find all CCAnswers: (diameter.flags.request == 0) && (diameter.cmd.code == 272)

but to find related CCR/CCA, I need to use a filter on diameter.Session-Id == "bla bla bla" since CCR and related CCA will have the same session id

My issue is find all CCRs and related CCAs

I should use something like for CCR = x to CCR = n , where session id = bla bla bla x find related CCA

is it possible in wireshark?

Thanks in advance, Michele

(Assuming CCR is the diameter.CC-Request-Number)
For the sample capture:
diameter.Session-Id == "GatewayService-7-10-0.NeveNG7;1368477994;1073741858" and diameter.CC-Request-Number in {1..3} and (diameter.flags.request == 0) && (diameter.cmd.code == 272)

I'm not a diameter wiz so guessing at the fields.
