Ostinato v1.1 / Linux / QT5 v5.15.2

I imported a STP packet from a PCAP file stp.pcap.zip. The import runs without any issues.

But in Protocol Data the MAC address in the Spanning Tree Protocol section looks strange, correct is 0C:A2:8F:87:1D:00.
STP_protocol_data

In Paket View the packet is correct, so that's not an import issue.
STP_packet_view

After some head scratching I found, that this is a formatting issue. The correct MAC address 0C:A2:8F:87:1D:00 is shown as CA 28 F8 71 D0 0. The leading zero is dropped, what results in a MAC address, that looks completely different.

@b-ehlers : Could you attach the pcap packet that you imported?

I did in the initial comment.

I imported a STP packet from a PCAP file stp.pcap.zip.

This zip file stp.pcap.zip contains the pcap file you are asking for.
