簡介
本文檔說明從源Cisco安全管理裝置(SMA)到目標SMA的備份過程失敗並出現錯誤「Server denied roaming - [Errno 32] Broken pipe」的原因。
背景資訊
確保滿足以下備份限制和要求：
- 相同的AsyncOS版本
- 網路中的目標SMA
- 使用安全外殼(SSH)的裝置之間的通訊
- 目標裝置的容量等於或大於
- 一次只能運行一個備份進程
問題
將資料從一個SMA備份到另一個SMA時，備份會失敗。請在此處檢視備份日誌中顯示的錯誤消息：

解決方案
當系統嘗試繼續並使用已關閉的連線時，通常會出現[Errno 32] Broken pipe錯誤。檢查任何潛在的第2層問題，並使用CLI檢視兩個SMA上etherconfig > media和netstat -ni的結果。

接收的裝置(target_SMA)會在Management和Data 1乙太網介面上顯示輸入錯誤。如果檢查target_SMA所連線的交換機，您會發現問題出在SMA與Cisco交換機之間的不相容性。儘管會自動偵測介面速度和雙工，但兩個裝置無法選擇相同的設定。SMA檢測到100baseTX全雙工，但交換機上只有100baseTX半雙工，必須配置為100baseTX全雙工。
