我正在尝试在我的 HP DL160 G6（Xenserver）上设置 SNMP 陷阱，以便在服务器出现问题时通知我。
遵循以下建议此 serverfault 帖子，我安装了 HP SNMP 代理，并配置了它，cma.conf以便每当生成 SNMP 陷阱时都给我发送电子邮件。为了测试它，我拔掉了辅助 NIC。
我的问题是，我不是只得到一个表明 NIC 断开或重新连接的陷阱，而是每 10 秒生成一次陷阱来表明链接已关闭或已打开。
我还安装了 HP 系统管理 Web 界面，但似乎找不到如何配置 NIC 代理以停止每 10 秒发送一次陷阱并且仅在状态改变时发送陷阱。
这可能吗？
启用 SNMP 代理（cmanicd）后，我得到以下内容/var/log/messages：
