iSM：指派給 iDRAC USB NIC 的低指標 與 IPv4 解析度或叢集活動訊號衝突

Summary: 解析本機主機名稱的網域名稱系統 （DNS） 可能會傳回由 iDRAC Service Module （iSM） 啟用的 USB 網路介面卡 （NIC） 直通裝置的內部 IP 位址。這可能會導致使用 169.254.x.x 不可路由位址配置的內部網路設備出現問題。USB NIC 裝置的指標應手動設定為較高的數字，讓內部網路裝置具有優先權。

Symptoms

某些第三方產品和服務依賴於將主機的本地 DNS 名稱解析為主機中最快的網路介面。Windows 通過在確定路由表時根據介面的額定速度自動分配指標值來確定此順序。

如果啟用 iDRAC 的作業系統傳遞功能，則顯示的 USB NIC 可能會指派一個與其他 NIC 相同或更低 （更快） 的值。這可能會導致 nslookup 使用 USB NIC 內部解析主機 169.254.x.x 地址。

若要查看 Windows 為 InterfaceMetric 包括 USB NIC 在內的所有介面值，請使用 PowerShell：

Get-NetIPInterface | sort InterfaceMetric

Cause

iDRAC 服務模組會嘗試將指標指派給僅能與 iDRAC 進行內部通訊的 USB NIC 網路裝置。其效力可能優先於指標較低的內部裝置。

Resolution

這不會導致多種內部 Windows 服務發生問題，但已發現會導致某些第三方服務發生問題，例如需要可路由位址的 Web 代理伺服器。也出現與指派的 NIC 的衝突 169.254.x.x 具有較高（較慢）指標的位址，用於對檢測信號進行聚類。

工程部門建議覆寫具有較高值 （例如 999） 的自動 USB NIC 指標。您可以在 Windows 使用者介面中開啟 USB NIC 介面的 IPv4 屬性，然後按一下進階 > IP 設定，並在輸入 999 之前清除自動指標。或者，也可以使用 PowerShell 使用以下命令完成：

Set-NetIPInterface -ifindex <interface #> -InterfaceMetric 999

iDRAC Service Module （iSM） 必須啟用此 USB NIC 介面，且在較高 （較慢） 的指標下仍可正常運作，且無效能問題。
