The query_bck_cs_trace command returns information about the current options
for back-level client-server tracing. Client-server tracing is the
tracing of data sent between a current-level SNAplus2 server and a
back-level server or client. This command is used only when you
are in the process of migrating a client-server SNAplus2 system
to a new release of the software, so that one or more servers are
running the current-level software and providing support for computers
running the back-level software. For more information about the
upgrade process and about support for back-level computers, refer
to the HP-UX SNAplus2 Upgrade Guide.
This command must be issued to a running node on a computer
where the back-level support software is running.
