This verb returns information about the current options for
back-level client-server tracing (tracing of data sent between a
current-level SNAplus2 server and a back-level server or client).
It is used only when you are in the processs 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 migration process and on support for back-level
computers, see the HP-UX SNAplus2 Upgrade Guide.
This verb must be issued to a running node on a computer where
the back-level support software is running (for more information,
see the HP-UX SNAplus2 Upgrade Guide).
