Python implements the datastore device port monitoring example

Recently, due to the work needs, the above requirements, every day to report the operation and maintenance of several hundred through equipment port use situation [], although there is a ready-made network management monitoring tools to monitor the status of equipment, but the report, a little inconvenient, close-up of a small script.

Note: the test runs on ubuntn. Snmpwalk tool shall be installed.

The target digital device needs to be configured with SNMP
