ltsカーネルを使用したArch Linux
systemd networkdは、スマートスイッチ（DGS-1210-28）を使用して2つのNICをLACPリレーにバインドするように構成されています。ただし、起動後にオペレーティングシステムにエラーが発生します。接続された接続には1つのネットワークカードのみが使用されます。 /proc/net/bonding/*に示すように

ボンドにはAggregatorID = 2があり、未使用（変更）NICにはAggregatorID = 1があり、これは奇妙です。債券のAggregatorID = 1が必要です。
この問題は、物理ポートを介して変動したNICを再接続することによって「修正」することができます。その後、両方のNICがボンディングによって使用されます。これはカーネルログで確認できます。
