You need to determine the VOS image currently running on a branch CPE before scheduling a software upgrade. Which command provides this information?

The show system package-info command is the standard Versa Operating System (VOS) command to display detailed information about the installed software packages. The output includes the currently active (running) software version, the version stored in the alternate partition, and the factory base version. This is the precise command needed to determine the running VOS image before an upgrade.

show system uptime displays how long the device has been operational, not the software version.

show interfaces brief provides a summary of the status of network interfaces, not software information.

show class-of-services interfaces brief displays Class of Service statistics for interfaces, which is unrelated to the installed OS image.
