How to capture traces.
Before you capture traces, I suggest you can save it as a file. For CRT tool
① telnet the 2 terminals,admin/password is debug/debug.or debug/Change_Me
② enter the command “mc set trace 2”.
enter the command “sip trace on all”.
enter the command “trace on”.
to open trace of terminal and make the issue occur then
trace off. And feedback the file to us.
