How to find the TLS version of the client connecting to JazzSM/DASH in the logs?
Steps
If you want to see the client protocol, you must take an SSL trace on the server.

Use this trace string to see both client TLS version and also the IP.
SSL=all:HTTPChannel=all:TCPChannel=all:GenericBNF=all:SSLChannel=all
Once tracing is enabled, the following can be seen in <JazzSM_Home>/profile/logs/server1/trace.log. Protocol version - next to ClientHello, remote = Client IP:port, local = JazzSM/DASH IP:port
