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點對點配置有通過幀中繼的本地確認。show bstun命令輸出中的相關狀態已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。
