#! /usr/bin/env python
from genie.testbed import load
# Load the testbed
tb = load('testbed.yaml')
# Find the device with alias uut
dev = tb.devices['uut']
# Connect to the device
dev.connect()
# Parse the output of the show version command
output = dev.parse('show version')
# Extract the version number and print it to
the screen
print('IOS-XE version number: ' +
output['version']['version'])The output variable is a Python dictionary that contains
the JSON standardized data returned by the show
version command. This makes it very easy to parse and
extract the needed data from the output of the show
command.
