3.9.2リトライの分析

AP には、リトライが複数回行われたパケットの統計情報が記録されます。 この統計情報を使用して、リトライが過度に行われたパケットを確認して ください。リトライが行われるのは、送信元のステーションが送信パケッ トに対する応答を受信できなかった場合です。このように応答を受信でき ない場合、以下のような原因が考えられます。

複数のステーションが同時に送信を行ったため、パケットの衝突が発 生している。

受信側ステーションが通信範囲外にある。

受信側ステーションの電源がオフになっている。

以上のような原因により、両デバイスは送信を中止し、後にリトライしま す。リトライ数が多すぎる場合は、システムに問題がある可能性がありま す。

リトライの頻度を確認する手順は、以下のとおりです。
