問：Solarwinds Orion NPM 支援「Interface CRC Error」Alarm 嗎？
答：It is possible. If the deivce mibs has OID for CRC errors, NPM can create an alert for CRC detected. But we will need to use the Universal device poller to poll for the information. Universal device poller is part of Orion NPM installation.

問：Solarwinds Orion NPM 主機應該架設在哪裡？
答：只要監控的對象可以 Ping 得到主機即可。

問：沒有 Netflow 狀況下是否可以做到監控？
答：可以，監控到第二層（Node、Traffic、Event、Alert、Interface）。

問：是否有透過 Mirror 方式來收集？
答：Mirror 方式是設備的 Proxy 功能，Solarwinds Orion NPM 是直接接收監控封包。

問：當網路斷線時是否可以發送簡訊？
答：可以。雖然 Solarwinds Orion 本身並無內建簡訊系統，但可以搭配簡訊系統發送障礙通告，多數簡訊平台皆可透過內部網路來發送簡訊。

答：都支援。

問：是否支援 Cisco Router 及 PIX Firewall 的設定變更監控？
