升級您的參考設定檔 (RCF)
建議變更
PDF
當您的運行交換器上已安裝了現有版本的 RCF 檔案時，您需要升級 RCF 版本。
請確保您擁有以下物品：
-
交換器配置的目前備份。
-
一個功能齊全的群集（日誌中沒有錯誤或類似問題）。
-
當前的RCF。
-
如果您要更新 RCF 版本，則需要在 RCF 中進行啟動配置，以反映所需的啟動映像。
如果需要更改啟動配置以反映目前的啟動映像，則必須在重新套用 RCF 之前進行更改，以便在以後的重新啟動中實例化正確的版本。
|
在此過程中不需要任何可操作的交換器間連結 (ISL)。這是設計使然，因為 RCF 版本的變更可能會暫時影響 ISL 連線。為確保叢集運作不會中斷，以下步驟將所有叢集 LIF 遷移到運作夥伴交換機，同時在目標交換器上執行對應步驟。 |
|
在安裝新的交換器軟體版本和 RCF 之前，必須清除交換器設定並執行基本設定。您必須使用序列控制台連接到交換機，或在擦除交換器設定之前保留基本設定資訊。 |
第一步：準備升級
-
顯示每個節點上連接到叢集交換器的叢集連接埠：

步驟 2：設定埠
-
在叢集交換器 cs1 上，關閉連接到節點叢集連接埠的連接埠。
cs1> enablecs1# configurecs1(config)# interface eth1/1/1-2,eth1/7-8cs1(config-if-range)# shutdowncs1(config-if-range)# exitcs1# exit
請務必關閉所有已連接的叢集端口，以避免任何網路連線問題。請參閱知識庫文章 "在切換作業系統升級期間遷移叢集 LIF 時，節點脫離仲裁。"更多詳情請見下文。 -
驗證叢集 LIF 是否已故障轉移到叢集交換器 cs1 上託管的連接埠。這可能需要幾秒鐘。

如果您尚未儲存目前交換器配置，請將以下命令的輸出複製到文字檔案中：
show running-config-
記錄目前版本與目前版本之間的任何自訂新增內容。 `running-config`以及正在使用的 RCF 檔案（例如貴組織的 SNMP 配置）。
-
從 NX-OS 10.2 開始，使用 `show diff running-config`用於與 bootflash 中儲存的 RCF 檔案進行比較的命令。否則，請使用第三方差異/比較工具。
-
-
儲存基本配置詳細信息 `write_erase.cfg`啟動閃存上的檔案。
確保配置以下內容：
-
使用者名稱和密碼
-
管理 IP 位址
-
預設網關
-
交換器名稱
cs1# show run | i "username admin password" > bootflash:write_erase.cfgcs1# show run | section "vrf context management" >> bootflash:write_erase.cfgcs1# show run | section "interface mgmt0" >> bootflash:write_erase.cfgcs1# show run | section "switchname" >> bootflash:write_erase.cfg -
-
升級到 RCF 版本 1.12 及更高版本時，請執行以下命令：
cs1# echo "hardware access-list tcam region ing-racl 1024" >> bootflash:write_erase.cfgcs1# echo "hardware access-list tcam region egr-racl 1024" >> bootflash:write_erase.cfgcs1# echo "hardware access-list tcam region ing-l2-qos 1280" >> bootflash:write_erase.cfg請參閱知識庫文章"如何在保持遠端連線的情況下清除Cisco互連交換器上的配置"更多詳情請見下文。
-
確認 `write_erase.cfg`文件已如預期填入：
show file bootflash:write_erase.cfg -
發出 write erase 指令以擦除目前已儲存的設定：
cs1# write eraseWarning: This command will erase the startup-configuration.Do you wish to proceed anyway? (y/n) [n] y -
將先前儲存的基本配置複製到啟動配置中。
cs1# copy bootflash:write_erase.cfg startup-config -
重啟交換器：
switch# reloadThis command will reboot the system. (y/n)? [n] y -
管理 IP 位址恢復正常後，透過 SSH 登入交換器。
您可能需要更新與 SSH 金鑰相關的 hosts 檔案項目。
-
使用下列傳輸協定之一將 RCF 複製到交換器 cs1 的 bootflash：FTP、TFTP、SFTP 或 SCP。
有關Cisco命令的更多信息，請參閱相應的指南。"Cisco Nexus 9000 系列 NX-OS 指令參考"指南。
此範例展示如何使用 TFTP 將 RCF 檔案複製到交換器 cs1 的啟動快閃記憶體中：
cs1# copy tftp: bootflash: vrf management Enter source filename: Nexus_9336C_RCF_v1.6-Cluster-HA-Breakout.txt Enter hostname for the tftp server: 172.22.201.50 Trying to connect to tftp server......Connection to Server Established. TFTP get operation was successful Copy complete, now saving to disk (please wait)...
-
將先前下載的 RCF 檔案套用到啟動快閃記憶體。
有關Cisco命令的更多信息，請參閱"Cisco Nexus 9000 系列 NX-OS 指令參考"。
此範例展示了 RCF 文件 `Nexus_9336C_RCF_v1.6-Cluster-HA-Breakout.txt`正在交換器 cs1 上安裝：
cs1# copy Nexus_9336C_RCF_v1.6-Cluster-HA-Breakout.txt running-config echo-commands
請務必仔細閱讀 RCF 的 安裝說明、重要說明 和 橫幅 部分。您必須閱讀並遵循這些說明以確保交換器的正確配置和操作。
-
請確認 RCF 檔案是否為最新版本：
show running-config檢查輸出結果以驗證是否擁有正確的 RCF 時，請確保以下資訊正確：
-
RCF橫幅
-
節點和連接埠設置
-
客製化
輸出結果會根據您的網站配置而有所不同。檢查連接埠設置，並參考發行說明，以了解您安裝的 RCF 版本是否有任何特定變更。
-
-
將先前對交換器配置所做的任何自訂設定重新套用。請參閱"審查佈線和配置注意事項"有關任何後續變更的詳細資訊。
-
確認 RCF 版本、自訂新增項目和交換器設定正確後，將運行設定檔複製到啟動設定檔。
有關Cisco命令的更多信息，請參閱"Cisco Nexus 9000 系列 NX-OS 指令參考"。
cs1# copy running-config startup-config[] 100% Copy complete -
重啟交換器cs1。在交換器重新啟動期間，您可以忽略節點上報告的「叢集交換器健康監視器」警報和「叢集連接埠關閉」事件。
cs1# reloadThis command will reboot the system. (y/n)? [n] y -
