Lab-8:Python for network automation – XML parsing

continuing from Lab-7 below is an example of XML parsing using etree.

Precondition:

• Juniper srx with NETCONF enabled
  • set system services netconf ssh
• NETCONF ncclient installed
  • sudo pip install ncclient

Procedure:

• This script follows these steps
  • connect to Juniper srx using NETCONF
  • get interface counts for interface ge-0/0/0 using this command ‘show interface ge-0/0/0 detail statistics’
  • search for stats group ‘traffic-statistics’, ‘input-error-list’, ‘output-error-list’ and print individual stats under the group also store them in Python dictionary
•  Python file (get_interface_stats.py) located here

 

Output:
