最近因工作需要，上面要求，每天需上报运维的几百数通设备端口使用情况【】，虽然有现成网管监控工具监控设备状态，但做报表，有点不方便，特写了个小脚本。

注：测试运行于ubuntn，需安装snmpwalk工具，

目标数通设备，需做好相关snmp配置

复制代码 代码如下:
#/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�佽浆鎹?
def portStatus(_s):
    if int(_s)==2:
        return \’down\’
    elif int(_s)==1:
        return \’up\’
    else:
        return \’none\’

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,\’#\’))

运行结果
