転送情報をデバッグし、ハードウェア転送プレーンのパケットパスをトレースするには、 show platform hardware fed switch
forward interface
コマンドを使用して、アップグレードを実行します。このコマンドは、ユーザ定義のパケットをシミュレートし、ハードウェア転送プレーンから転送情報を取得します。入力ポートでは、このコマンドで指定したパケットパラメータに基づいてパケットが生成されます。また、PCAPファイルに保存されているキャプチャされたパケットから完全なパケットを提供することもできます。
この項では、インターフェイス転送固有のオプション、つまり、 show platform hardware fed switch {switch_num|active|standby}forward interface コマンドを使用して、アップグレードを実行します。
