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-8import 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
