モジュールSNMPv2-SMIで「zeroDotZero」が見つかりませんでした

スイッチを検索して、特定のIPアドレスをホストしているスイッチを見つけるPerlスクリプトがあります。このスクリプトは、net-snmpライブラリを使用して、ホストが接続されている正しいスイッチが見つかるまで、イーサネットスイッチのデイジーチェーン（コア/ディストリビューション/アクセスを考えてください）をポーリングします。

このスクリプトはほとんどのLinuxマシンで正常に機能しますが、SNMPv2-SMIに「zeroDotZero」がないことを把握するSTDERRメッセージをスローするスクリプトがあります。

エラーメッセージを停止するにはどうすればよいですか？

net-snmpのデフォルトのSNMPv2-SMIコピーにはzeroDotZero ..の定義があります。

[mpenning@lnxlmf ietf]$ cd /usr/share/snmp/mibs/
[mpenning@lnxlmf mibs]$ grep zeroDotZero SNMPv2-SMI.txt
zeroDotZero    OBJECT-IDENTITY
[mpenning@lnxlmf mibs]$

CiscoMIBディレクトリにSNMPv2-SMI.myの古いコピーをインストールしたことが判明しました...このSNMPv2-SMI.myのコピーにはzeroDotZeroがなく、net-snmpのコピーを上書きしていたので削除しました。

[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

これで、スクリプトは問題なく実行されます...
