Python to monitor the port usage of the device, python to monitor the port usage of the device

This example describes how to monitor the port usage of a device using Python. Share it with you for your reference. The details are as follows:

Recently, due to work requirements, the above requirements need to be reported daily O & M of hundreds of port usage [], although there is a ready-made network management monitoring tool to monitor the device status, but reporting is a little inconvenient, close up a small script. Uploaded, available for semi-finished products

Note: snmpwalk must be installed to test running on ipvtn,

Related snmp configuration is required for the target DT-pass device.
