最近因工作需要，上面要求，每天需上報運維的幾百數通設備端口使用情況【】，雖然有現成網管監控工具監控設備狀態，但做報表，有點不方便，特寫了個小腳本。

注：測試運行于ubuntn，需安裝snmpwalk工具，

目標數通設備，需做好相關snmp配置

代碼如下:
#/usr/bin/python
#coding:utf-8

import os,sys
import re
from pprint import pprint

#甯歌鍘傚鏁伴?氳澶嘙IB鍊?
MIB = {
   'public':{
        'ports':{
           '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':{
   }
}
#绔彛鐘舵?佽漿鎹?
def portStatus(_s):
    if int(_s)==2:
        return 'down'
    elif int(_s)==1:
        return 'up'
    else:
        return 'none'

#鎵ц緋葷粺鍛戒護snmpwalk璋冪敤
def snmpwalk(host,publicKey,iso):
    return [i.strip() for i in os.popen('/usr/bin/snmpwalk -c %s  -v 2c %s %s'%(publicKey,host,iso)).readlines()]

def getPorts(_ip,_public,option):
    if option == 'ports':
        postsString = (j.split('=')[1].split(':')[1].replace('"','').strip() for j in snmpwalk(_ip,_public,MIB['public']['ports']['string']))
        postsStatus = (int(j.split('=')[1].split(':')[1].strip()) for j in snmpwalk(_ip,_public,MIB['public']['ports']['status']))
        return zip(postsString,postsStatus)
    else:
        print('on this commmnad')

publicKey = 'hi'  #sunmp public key

HOSTS={
    '10.221.98.2':{'type':'switch','origin':'quidway','public':publicKey},
    '10.221.98.3':{'type':'switch','origin':'quidway','public':publicKey},
    '10.221.97.108':{'type':'firewall','origin':'h3c','public':publicKey},
    '10.231.98.233':{'type':'switch','origin':'cisco','public':publicKey},
}
if __name__ == '__main__':
    for i in HOSTS.keys():
        for host,status in getPorts(i,HOSTS[i]['public'],'ports'):
            print("%s/t%s/t%s"%(i,host.ljust(30),portStatus(status).ljust(20)))
        print(''.ljust(50,'#'))

運行結果
代碼如下:
root@ubuntn12:/tmp# python snmpwalk.py
