Python implementation of digital device port monitoring sample _python

Recently due to work needs, the above requirements, daily need to report operational dimensions of the hundreds of-pass device port usage "", although there is a ready-made network management monitoring tools monitoring equipment status, but do a report, a little inconvenient, close-up a small script.

Note: The test runs in Ubuntn, the Snmpwalk tool must be installed,

Target number-pass equipment, need to do the relevant SNMP configuration
