Hello,

We are using our own Softwaretool, to get Signalling from mobile phones and then send it to Wireshark via Network Loopback-adapapter as GSMTab or UDP packet for further analysis.

This works great for all Signaling information except NAS-5GS, because (unlike LTE NAS-EPS) there is no dissector nas_5g_udp.

So will there be an according dissector in a future release of wireshark, or is there another way, to send the NAS-5GS to Wireshirk over UDP for analysis?

Hello,

Im getting the Expert Info Warning when im analysing 5G SIB8 Messages, received from our own 5G gNodeB.

"[Expert Info (Error/Malformed): Number of pages should be <=15 (found 201)]"

Other Tools don't show Problems with decoding the same Messages.

It would also be good, if the Wireshark dissector would also show the "DataCodingScheme" information.

As I am not allowed to attach files, because i'm new here, i can' provide PCAP, but maybe Hex Stream of the SIB8 may be helpfull:
