Clock Icon2024.01.23

困っていること

EC2(Windows Server) が使用しているネットワークドライバーのバージョンを確認する方法を教えてください。

どう解決すればいいの?

使用しているネットワークドライバーとバージョンは下記の手順で確認ができます。

  • 設定を開く
  • Network & Internet を開く
  • Ethernet を開く
  • Connected となっている Network Interface を開く
  • Description と Driver Version を確認する

また、下記の手順でも確認ができます。

  • PowerShell からpnputil -eコマンドを実行
  • 出力された結果から、Class が Network adapters となっているものを抽出し、Driver package provider と Driver date and version から推察し、Published name のファイルを%windir%\INFから開いて確認する

やってみた

Nitro インスタンスタイプの場合

t3.large インスタンスタイプで Windows Server 2022 の AMI(ami-0a7704dfcc8c70a27)からインスタンスを作成します。

PowerShell にて、インスタンスメタデータからNitroであることを確認します。

PS > $token = Invoke-RestMethod 'http://169.254.169.254/latest/api/token' -Method Put -Headers @{ "X-aws-ec2-metadata-token-ttl-seconds" = 21600 }
PS > Invoke-RestMethod 'http://169.254.169.254/latest/meta-data/system' -Headers @{ "X-aws-ec2-metadata-token" = $token }
nitro

Windows の設定では ENA ドライバーを使用していることが確認できました。

%windir%\INF(通常の場合は C:\Windows\INF)内のoem*.infというファイルを開くことで、各ドライバーの詳細が確認できます。

oem88.inf と oem2.inf 開いてみましょう。

DriverVer = 02/27/2023,2.6.0.0

こちらは ENA ドライバーのようです。バージョンも 2.6.0.0 であることが確認できます。

[Strings]

Vendor= "Amazon Inc."
DiskDesc = "AWS Tools for Virtual Machines"
XenNetName="AWS PV Network Device"

こちらは PV ドライバーのようです。バージョンはファイルからでは確認できないため、レジストリを参照しました。バージョンは 8.4.3 でした。

補足: xen on nitro の場合

c3.large インスタンスタイプで Windows Server 2016 の AMI(ami-0adb69d2336ea1b6e)からインスタンスを作成します。

PowerShell にて、インスタンスメタデータを確認したところ、xen on nitroでした。

PS > $token = Invoke-RestMethod 'http://169.254.169.254/latest/api/token' -Method Put -Headers @{ "X-aws-ec2-metadata-token-ttl-seconds" = 21600 }
PS > Invoke-RestMethod 'http://169.254.169.254/latest/meta-data/system' -Headers @{ "X-aws-ec2-metadata-token" = $token }
xen-on-nitro

xen on nitro についての詳細は参考資料をご参照ください。

Windows の設定では Intel 82599 VF インターフェイスを使用していることが確認できました。

oem2.inf ファイルが該当すると見えるため、内容を確認しました。

しかしながら、INTEL CONFIDENTIALの文字があったため、ブログ記事内での公開は控えます。

ですが、バージョン番号とドライバー名の記載はあったため、この方法で確認することはできると考えられます。
