本產品的文件集力求使用無偏見用語。針對本文件集的目的，無偏見係定義為未根據年齡、身心障礙、性別、種族身分、民族身分、性別傾向、社會經濟地位及交織性表示歧視的用語。由於本產品軟體使用者介面中硬式編碼的語言、根據 RFP 文件使用的語言，或引用第三方產品的語言，因此本文件中可能會出現例外狀況。深入瞭解思科如何使用包容性用語。

關於此翻譯

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

本檔案將提供序列通道(STUN)直接封裝的組態範例。show stun命令輸出的相關狀態和debug命令輸出的狀態變更顯示在本檔案的驗證和疑難排解一節中。

雖然debug stun packet和debug stun event命令不應導致CPU使用率過高，但是logging buffered命令用於將輸出複製到日誌檔案。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

本部分同時顯示兩台路由器的show stun命令輸出。它顯示每台路由器的STUN狀態是open。此外，每次發出show stun命令時，接收封包(rx_pkts)和傳輸封包(tx_pkts)的計數器都會增加。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

疑難排解指令

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

注意：發出debug命令之前，請參閱有關Debug命令的重要資訊。

  • debug stun packet — 顯示有關通過STUN鏈路傳輸的資料包的資訊。

  • debug stun event — 顯示STUN連線和活動。
