This chapter describes how to compare the differences between two revisions of a configuration file stored in the JUNOScope Concurrent Versions System (CVS) repository. Configuration files are stored in CVS when you archive or import them from a router or a group of routers or when you import them from a text file on your local file system.
By default, the JUNOScope software compares the newer revision of a configuration file to the older revision. You can select to compare an older revision of a configuration file to a newer revision.
To compare configuration files, there must be at least two revisions of the files in the CVS repository. JUNOScope displays the differences of the configuration file revisions in color or by prefacing the changes with plus signs (+) or minus signs (-).
All JUNOScope users can compare configuration files.
