首先使用snmpwalk跑一遍看一下有没有问题
snmpwalk -v 2c -c public 10.103.33.1
这里测试用交换机是 WS-C2960G-24TC-L，以下脚本用于读取管理ip,序列号,型号,主机名。思科的交换机snmp oid信息都可通过如下网址查询http://tools.cisco.com/Support/SNMP/do/BrowseOID.do
首先安装python的snmp依赖包
yum install net-snmp-python
获取信息的脚本

import urllib2
# reference python for linux and unix administration page 209
