If you want to know which Cipher suite / TLS protocol is most popular on your LPAR.
You can use SST to find out. So first run STRSST
1. Start a service tool
4. Display/Alter/Dump
1. Display/Alter storage
2. Licensed Internal Code (LIC) data
14. Advanced analysis
then use -connectionCounts:display command
Select Advanced Analysis Command
Output device . . . . . . : Display
Type options, press Enter.
