軟體升級後,安全防火牆威脅防禦(FTD)叢集資料節點無法加入叢集。觀察到以下症狀:
1. show cluster history的輸出顯示裝置從DATA_NODE_CONFIG轉換到DISABLED狀態時的「配置複製失敗」錯誤消息:

2.檔案/mnt/disk0/cluster_trace.log*包含與key命令的配置複製失敗和群集轉換為DISABLED狀態相關的消息:

3.檔案/ngfw/var/log/ASAconsole.log*還包含與key命令的配置複製失敗和群集轉換為DISABLED狀態相關的消息:

在多例項集群部署中採用FTD的Firepower 4145。在多例項或本機模式部署中在Firepower 4100/9300上運行的群集也會受到影響。
FTD叢集由FMC管理。
FTD軟體版本從7.6.2升級到7.6.4。其他來源或目標軟體版本也可能會受到影響。
最初,群集金鑰配置為64個字元長度的字串。根據Secure FXOS for Firepower 4100/9300 CLI或機箱管理器(FCM)配置指南中的「邏輯裝置」部分,集群金鑰是長度為1到63個字元的ASCII字串。因此,使用FCM使用者介面邏輯裝置設定,群集金鑰長度減少到少於64個字元。
雖然已記錄集群金鑰的最大長度限制,但在FXOS軟體級別(FXOS CLI或FCM)不會強制執行該限制。允許使用者配置超過字元數的集群金鑰。儘管字元數達到最大值,但裝置仍可以在7.6.2版中加入群集。但是,升級之後,軟體將強制驗證導致無法加入群集的金鑰長度。這是未記錄的行為更改。思科錯誤ID CSCwn53819會在內部複製並追蹤這些症狀。
此外,作為重現工作的一部分,已提交思科錯誤ID CSCwu3563和思科錯誤ID CSCwu3553,以分別跟蹤FCM和FXOS CLI上缺少群集金鑰長度驗證的情況。
