Appendix A: Custom CLI commands (pySROS)

Custom Python applications can be written to run on SR OS. One example of an application is a custom CLI command. The following sample configuration shows how to configure a Python script get_all_interfaces.py to display all VPRN interfaces and the in/out packets in one output. For sample Python scripts, visit the Nokia pySROS GitHub repository.

For more information about pySROS, see the 7450 ESS, 7750 SR, 7950 XRS, and VSR System Management Guide and the pySROS API documentation.
