Some additional tips from Roger (http://rogerthephoneguy.com/) thank you ….
By the way, the engineer I worked with always uses the -uni option when he starts traceSM or traceSBC. It uses unicode characters for the lines and arrows and looks MUCH cleaner on the screen. He also typically adds the filters -no -na -u xxxx at the command line when he starts the trace. And lastly, when analysing a saved trace file, he uses the -dt option. He said it “disables data throttling” and saves a few cycles.
When you write a file during a trace, you have to untar it. There will be what looks like a pcap file (It’s a pcapng). He said it’s close to a pcap, but it’s not readable within wireshark.
