When you add a nonnative YANG RPC to a device, you must also supply an action script that serves as the RPC’s handler. Junos PyEZ configuration Tables and Views provide a simple and efficient way to extract specific information from the selected configuration database of a Junos device. The term "metaprogramming" means that the rpc will dynamically create Junos OS XML Remote Procedure Calls (RPCs) as you invoke them, rather than pre-coding them as part of Junos PyEZ Basic Demo. Event scripts can execute these XML commands on a local or remote device using the remote procedure call (RPC) protocol. jsnapy import SnapAdmin from pprint import pprint from jnpr. config import Config. The second item contains the command output that the device returns. The most common use for bind is attaching Utility instances to a :class:Device.
