CML2 でノード起動前にコンフィグを設定する
CML2 ではノードを起動する前に、予めコンフィグを設定しておくことが可能です。 今回はその手順をメモしておきます。 今回は IOSv (15.9) を使って検証しました。

CML2 上から初期コンフィグを設定する
CML2 でラボを作成してノードを配置した後、以下の手順で操作します。
- 事前コンフィグを設定したいノードを選択する
EDIT CONFIG を選択する- 事前コンフィグを入力する
- (このままだとコンフィグ右上に
Unsaved changes と表示されたままになるので) SAVE を選択し、コンフィグを保存する
今回は以下のコンフィグを入力しました。

ノード起動後のコンフィグ (二回目以降)
IOSv の場合、コンフィグを保存した後で再起動すると以下の挙動になりました。
- 変更したコンフィグは反映されている
- しかし、仮に
banner は削除してあっても復活してしまう
