Mastering Python Networking - Second Edition

PyEZ examples

In the previous interactive prompt, we already saw that when the device connects, the object automatically retrieves a few facts about the device. In our first example, junos_pyez_1.py, we were connecting to the device and executing an RPC call for show interface em1:

      #!/usr/bin/env python3      from jnpr.junos import Device      import xml.etree.ElementTree as ET      import pprint      dev = Device(host='192.168.24.252', user='juniper', passwd='juniper!')      try:          dev.open()      except Exception as err:          print(err)          sys.exit(1)      result =     dev.rpc.get_interface_information(interface_name='em1', terse=True)      pprint.pprint(ET.tostring(result))      dev.close()

The device class has an rpc property that includes all operational commands. This is pretty awesome because ...
