This protocol is the layer 2 protocol of the UTRAN Iub interface between a Node-B and an RNC. For instance, it maps logical channels (BCCH, PCCH, DCCH, …) to transport channels (PCH, FACH, RACH, …). The protocol and its functions are specified in 3GPP TS 25.321.
- MAC runs over FP (Frame Protocol), both for Control and for Data connections
- MAC calls the RLC (Radio Link Control) protocol for further dissection
At the moment, no example traffic is available
The MAC dissector is partially functional (it only supports FDD, not TDD mode). Dissection is possible for RACH, FACH, PCH, DCH, E-DCH and HSDSCH.
To correctly dissect frames, the MAC dissector requires per-frame information on whether or not a C/T MUX field is present and what kind of content the frame contains. At the moment, this information can be generated by using the FP Hint protocol.

You cannot directly filter PROTO protocols while capturing.
