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.
Configuring a python script
configure python python-script "get_all_interfaces" { admin-state enable }
configure python python-script "get_all_interfaces" { urls ["cf3:\get_all_interfaces.py"] }
configure python python-script "get_all_interfaces" { version python3 }
configure system management-interface cli md-cli environment command-alias { alias "all-interfaces" }
configure system management-interface cli md-cli environment command-alias { alias "all-interfaces" admin-state enable }
configure system management-interface cli md-cli environment command-alias { alias "all-interfaces" description "show all VPRN interfaces" }
configure system management-interface cli md-cli environment command-alias { alias "all-interfaces" python-script "get_all_interfaces" }
configure system management-interface cli md-cli environment command-alias { alias "all-interfaces" mount-point "/show" }
# show all-interfaces
