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

' String ': '. 1.3.6.1.2.1.2.2.1.2 ',
' Status ': '. 1.3.6.1.2.1.2.2.1.8 ', #2 down
}
},
' Huawei ': {

},
' Cisco ': {
}
}

def portstatus (_s):
if int (_s) ==2:
Return ' Down '
elif Int (_s) ==1:
Return ' Up '
Else
