CML2 に NX-OS 9300V を登録する手順をメモしておきます。

OS イメージのダウンロード

CCO の NX-OS 9000v Switch のページ から CML2 へアップロードする OS のバイナリイメージをダウンロードします。 今回は nexus9300v.9.3.8.qcow2 をダウンロードしました (※ 当然ですが OS をダウンロードする権限を保有している必要があります)。

Node Definition

予め、以下の内容で .yaml ファイルを定義しておきます。 次に CML2 の Web UI へアクセスし TOOLS → Node and Image Definitions → IMPORT を選択し、定義しておいた .yaml ファイルを読み込みます。
