Python scripts run inside the sandbox, using the Pyrthon API to communicate with the Device Interaction Server (DIS) on NetMRI. The DIS proxies CLI requests/responses to/from network devices on behalf of the Python scripts. Before commands can be sent to a network device, a Python script must first establish a DIS session (see v2 API object DisSession). After a session has been established, a CLI connection with the target device must be established for the given session (see v2 API object CliConnection). The majority of the time, a Python script will follow this same initialization sequence. First, establish the API session, establish the DIS session, then establish a CLI connection with the target device. For this reason, netmri_easy.py, a pre-installed Python library, is provided in the appliance (see Configuration Management –> > Job Management –> > Library –> > netmri_easy).
