我有一个Perl脚本，通过我们的交换机searchfind哪一个托pipe给定的IP地址; 此脚本使用net-snmp库来轮询以太网交换机的菊花链（思考核心/分发/访问），直到find主机连接的正确交换机。
这个脚本在我们的大多数linux机器上都能正常工作，但是我有一个引发STDERR消息的信息，它们在SNMPv2-SMI丢失了'zeroDotZero'

我怎样才能停止错误信息？
SNMPv2-SMI的默认net-snmp副本定义了zeroDotZero …
[mpenning@lnxlmf ietf]$ cd /usr/share/snmp/mibs/ [mpenning@lnxlmf mibs]$ grep zeroDotZero SNMPv2-SMI.txt zeroDotZero OBJECT-IDENTITY [mpenning@lnxlmf mibs]$
事实certificate，我已经在我的思科MIB目录中安装了一个旧版本的SNMPv2-SMI.my … SNMPv2-SMI.my这个副本没有zeroDotZero，并且正在覆盖net-snmp的副本，所以我删除它。
[mpenning@lnxlmf mibs]$ cd /usr/share/snmp/mibs/cisco/ [mpenning@lnxlmf cisco]$ grep zeroDotZero SNMPv2-SMI.my [mpenning@lnxlmf cisco]$ sudo rm SNMPv2-SMI.my
现在脚本运行没有问题…
