Question

A network engineer writes an on-box Python script to run on a Nexus 9000 switch. The script must execute the show CLI command 'show interface brief', parse the returned data programmatically, and iterate over each interface. The engineer wants the command output returned as structured data rather than raw text so the parsing logic stays simple. Which approach within the on-box Python interpreter meets this requirement?

Accepted Answer

Use the clid() function from the cli module to return the command output as JSON-formatted structured data

Answer

Use the cli() function from the cli module, which returns plain text that must be regex-parsed line by line

Answer

Use the clip() function from the cli module, which prints output directly to the terminal and returns None

Answer

Invoke the command through os.system() so the shell captures the CLI output as a Python dictionary
