Python implements a digital device port monitoring example

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.

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

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

Copy the Code code as follows:

#/usr/bin/python
#coding: Utf-8

Import Os,sys
Import re
From Pprint import Pprint

}
},
' Huawei ': {

' Cisco ': {
}
}
