使用通過幀中繼的本地確認配置BSTUN點對點

簡介

Bisync序列通道(BSTUN)功能支援使用Bisync資料連結通訊協定的裝置。此通訊協定允許企業透過支援其系統網路架構(SNA)和多通訊協定流量的同一網路傳輸Bisync流量，消除對獨立Bisync設施的需要。通過幀中繼，您可以使用本地確認功能在BSTUN對等體上提供會話的本地終止。

在本示例中，BSTUN點對點使用幀中繼本地確認進行配置。show bstun命令輸出中的相關狀態在本文檔中突出顯示。

註：雖然debug bstun packet/event和debug bsc packet/event命令不應導致CPU使用率過高，但使用logging buffered命令將輸出複製到日誌檔案。

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

debug bstun packet/event和debug bsc packet/event輸出已複製到日誌檔案。解釋此debug輸出時：

• 序列資料傳入(SDI) — 從同步資料連結控制(SDLC)介面接收的封包。

• 網路資料傳入(NDI) — 從WAN解封裝的資料包。

注意：發出debug指令之前，請參閱有關Debug指令的重要資訊。
