Hi,

I have installed the wireshark version 1.10.5 but not able to dissect rrc.ul.ccch and rrc.dl.ccch message such as rrcConnectionRequest and rrcConnectionSetup in the capture of Iub interface. The same capture you can find as attachment. 

But some of the messages I can see when we apply rrc filter such as rrcConnectionSetupComplete and other.

Please suggest me there is any setting parameter I want to set to dissect RRC connection request and setup or there is any problem in the dissector. 

This will be very helpful to me. Thanks in advance.

Hi Ashutosh,

your capture seems to contain only the FP DCH channel data and not the RACH channel data, so it is normal if you do not see UL or DL CCCH messages.
You should double check whether such packets can be captured on your equipment or not.

Best regards,
Pascal.
