デフォルトでは、Network Managerはネットワーク間の切り替えを処理しません。

ラップトップとさまざまなドッキングステーションを使用して、異なるネットワーク間で継続的に切り替える必要があります。特定のネットワークからノートブックを削除してから、同じネットワークに戻しても問題はありません。別のネットワークに移動すると問題が発生します。

どういう意味でもひどい問題ではありませんが、少し迷惑なようです。

質問：別のネットワークに移行するときは、イーサネットインターフェイスを終了してすぐに再起動しなければ、ネットワーク管理者はDHCPトランザクションを正しく実行できます。

ネットワーク管理者がこのタスクを自動的に実行するように構成する方法はありますか？または、新しいネットワークに接続したときに実行されるスクリプトを使用する必要がありますか？後者の場合、イベントをどのようにキャプチャしますか？

編集する詳細は：

ドッキングステーションはこれ一つ。イーサネットポートはドック自体にあります。考えるインターフェイスはPCIバスです。ドックのイーサネットインターフェイスがラップトップのイーサネットインターフェイスとは独立しているかどうかはわかりませんが（たとえば、別のNIC - これをどのように確認できますか？Dmesgでこれを示すようです）、これが問題の原因である可能性があります。 。

これが真であれば、スタンドアロンネットワークカードの接続と取り外しは、イーサネットケーブルの接続と取り外しとは異なりますか？以下の説明に従って、単純なudevルールを使用してこの問題を処理できると思いますが、ネットワーク管理者がこのイベントを処理する方法の詳細については役に立ちます。
