CMLでEnterprise SONiCを使う

2023/12/31に公開

network

【概要】

CML(Cisco Modeling Labs)では、利用可能なプラットフォームは、標準で用意されているものに加えて自分で定義して利用することも可能です。

この手順はユーザガイドに示されています。

またSONiCでは、各社から商用ディストリビューション（Enterprise SONiC）が提供されています。

Enterprise SONiC Distribution by Edgecore

Enterprise SONiC Distribution by Dell Technologies

Enterprise SONiCは、提供する企業によっては、仮想化環境で利用可能なイメージが公開されています。

今回は以前構築したESXiホストにインストールされたCML 2.2.3の環境で、仮想マシン用のEnterprise SONiCイメージを用いてセットアップを試みたところ、利用を開始できる状態となりました。
以降はその記録となります。

【詳細】
