挂起的管理中的网络监视网络设备

System.NetworkManagement.NetworkDevicesInPendingManagement (UnitMonitor)

此监视器检查网络发现对于多个网络设备是否失败。

Knowledge Base article:

摘要

无法发现网络设备，并且这些设备处于挂起的管理中。

原因

处于挂起的管理中的网络设备可能是由提供的 SNMP 凭据的问题、间歇性网络延迟或 SNMP 流量意外堵塞导致的。

解决方法

请检查以确保在网络发现期间提供的 SNMP 凭据仍然有效。确保防火墙规则未阻止 SNMP 访问所监视的设备。请与网络管理员联系以进行其他故障诊断。
