Python implements a digital device port usage monitoring instance

The example in this paper describes how Python implements monitoring of port usage for several-pass devices. Share to everyone for your reference. Specific as follows:

Recently due to work needs, the above requirements, the daily need to report operation and maintenance of the hundreds of number of devices port usage "", although there are ready-made network management monitoring tools to monitor the status of the device, but do report, a little inconvenient, close up a small script. Uploaded, available for semi-finished programs

Note: The test runs on UBUNTN, you need to install the Snmpwalk tool,

Target number of devices, need to do the relevant SNMP configuration
