wireshark, viewing Abis communication

Hi,

I am trying to deal with wireshark to understand what happening in each function in the code. It says that the file seems to be corrupted: "The capture files appears to be damaged or corrupted. (libpcap: LAPD file has a 15-byte packet, too small to have even a LAPD pseudo-header)"

Is it a problem?

I still can read the Abis communication. I saw that some rsl packets are malformed. Is it coming from a missing implementation in the code that need to be fixed?

Thanks

Eric
