思科已使用電腦和人工技術翻譯本文件,讓全世界的使用者能夠以自己的語言理解支援內容。請注意,即使是最佳機器翻譯,也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責,並建議一律查看原始英文文件(提供連結)。
本文說明如何升級 Cisco Catalyst 3850 系列交換器,並提供發生軟體或開機失敗時的復原技巧。
思科建議您瞭解以下主題:
本文件中的資訊是以執行 Cisco IOS XE 03.03.00 及更新版本的 Cisco Catalyst 3850 系列交換器為依據。本文件中的範例使用堆疊式解決方案;但是,您也可以在獨立交換器上執行相同的命令。
附註:若要從思科網站下載 Cisco IOS XE 映像,您必須擁有具有授權認證的有效 Cisco Connection Online (CCO) 帳戶。思科未提供免費的 TFTP/FTP 解決方案。開始之前,請安裝並設定 TFTP/FTP。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除(預設)的組態來啟動。如果您的網路運作中,請確保您瞭解任何指令可能造成的影響。
Cisco Catalyst 3850 系列交換器有兩種運作模式:安裝和套件組合。
這兩種模式之間存在細微差異。有關詳細資訊,請參閱組態設定指南。
思科建議在作業期間使用安裝模式,因為此模式可使用更完整的功能集,且開機時需要的資源較少。本文件簡要概述這兩種模式以供參考。
這是交換器的預設模式。安裝模式使用名為 packages.conf 的套件佈建檔來將交換器開機。此外,快閃記憶體中有許多 .pkg 檔案。 除非有思科技術援助中心 (TAC) 工程師提供指導,否則思科建議不要修改這些檔案。
如果您偏好使用傳統的單一 Cisco IOS 映像來啟動交換器,則可能會熟悉套件組合模式。
套件組合模式耗用的記憶體比安裝模式還多,這是因為需從套件組合中擷取套件並將其複製到 RAM 中。
若要驗證模式,請輸入 命令:show version
3850-stack#show version

* 2 56 WS-C3850-48T 03.03.00SE cat3k_caa-universalk9 INSTALL
若要開始升級程序,請從思科網站下載 Cisco IOS® XE .bin 檔案,然後將其放在作用中交換器的快閃記憶體中。本文件沒有說明將檔案複製到交換器的程序。
注意:請務必注意,此進程顯示了升級運行較早3.x.x版本的3850交換機所需的命令。要升級運行16.x.x版本的3850交換機,請使用命令request platform software package install switch all file <file>或install add file <file> activate commit。有關其他詳細資訊,請參閱Cisco Catalyst 3850系列交換機發行版本註釋。
將 .bin 檔案複製到單個交換器時,安裝程序會將該檔案複製到堆疊中的其他交換器上。一旦檔案存在,請輸入以下指令:
3850-stack#software install file flash:cat3k_caa-universalk9.SPA.03.03.01.SE.150-1.EZ1.bin switch 1-2
附註:在每個命令之後,有許多選項可供選擇;但是,此範例僅執行基本升級。
升級程序開始時,交換器會將 .bin 檔案推送到對等堆疊成員。

舊版的剩餘檔案仍保留在快閃記憶體中。若要清理殘餘檔案,請輸入 命令,而非手動刪除檔案。software clean
此命令可清除交換器不再需要的檔案。
附註:此命令也會刪除用來安裝新 Cisco IOS 軟體的 .bin 檔案。請務必留意,一旦擷取此檔案,就再也不需要它了。
接下來的兩節將提供範例,說明使用 命令之前和之後快閃記憶體如何顯示。software clean

如果您購買新交換器,則必須在 Catalyst 3850 系列交換器的目前堆疊中引入一部新交換器,以便擴展堆疊中可用的連接埠數量。 若要成功將新交換器新增到堆疊中,必須確保新交換器上執行的軟體版本相同。在 Cisco IOS XE 3.3.1 版之前的版本中,確保版本相符的唯一方法,是在引入堆疊之前暫存新交換器。
Catalyst 3850 系列交換器包含稱為自動升級的功能。此功能的目標是確保堆疊成員自動使用正確的 Cisco IOS XE 版本來佈建新增的交換器。
附註:自動升級功能預設為停用,且無法在套件組合模式下使用。
若要使用自動升級功能,請將 命令新增到目前堆疊的組態中。software auto-upgrade enable
這可確保所有新增的堆疊成員均自動升級。
堆疊交換器並啟動後,會顯示版本不符的指示,且新成員並未完全加入堆疊。
若要在交換器嘗試加入時查看系統日誌,請注意,自動建議功能會提醒新增的交換器執行不同的軟體版本和模式。
附註:在此範例中,新交換器在套件組合模式下執行 IOS XE 3.2.2 版。

在「全域組態」模式下,輸入 命令。software auto-upgrade enable
此指令會為加入堆疊的所有新交換器啟用該功能。

僅重新載入最近新增的交換器;無須重新載入完整堆疊。在此案例中,新增的交換器是 switch 3,因此輸入了 reload slot 3 指令。
提示:這些命令中提到的 slot 會指定堆疊中的交換器 (slot 1 = switch 1)。

本節說明 3850 系列交換器啟動失敗(例如啟動映像損毀、packages.conf 檔案損毀或缺少檔案)的可能復原方法。
附註:請確保您具備兩種可能啟動模式的知識(即安裝和套件組合),然後再繼續。
本節介紹兩種標準方法,用於從 Catalyst 3850 系列交換器開機失敗中復原。
3850 系列交換器的前面板上有一個 USB 連接埠,用於主控台存取。此 USB 連接埠還可搭配使用快閃磁碟機以進行映像備份和復原。
如果停滯在 switch: 提示且映像或 .conf 檔案已損毀,請啟動至儲存在 USB 磁碟機上的檔案,或者將映像從 USB 複製到內部快閃記憶體中。完成以下步驟,即可從開機失敗中復原:
switch: dir usbflash0:
Directory of usbflash0:/
74 -rw- 223734376 cat3k_caa-universalk9.SPA.03.03.00.SE.150-1.EZ.bin
switch: boot usbflash0:cat3k_caa-universalk9.SPA.03.03.00.SE.150-1.EZ.bin
附註:此程序會將交換器啟動至套件組合模式。
提示:您也可以將 .bin 檔案從 usbflash0: 複製到 flash:,然後將啟動陳述式指向內部快閃記憶體。
某些情況下,packages.conf 會呼叫已不存在於快閃記憶體中的檔案。您可以從 switch: 提示檔案手動啟動映像;但是,重新載入後,該映像會再次呼叫 packages.conf 檔案且無法啟動。 如果發生這種情況,思科建議備份目前的 packages.conf 檔案,並將其重新命名或刪除。這是必要程序,因為如果 .conf 檔案已存在,下一步就會失敗。
擷取 .bin 檔案後,系統會建立一個新的 packages.conf 檔案。完成這些步驟,便可從損毀的 packages.conf 檔案中復原:
Switch#dir flash:
Directory of flash:/
15500 -rwx 1243 Aug 1 2013 07:04:02 +00:00 packages.conf
Switch#cp flash:packages.conf flash:packages.conf.badop
Destination filename [packages.conf.bad]?
Copy in progress...C
1243 bytes copied in 0.140 secs (8879 bytes/sec)
Switch#dir flash:

15500 -rwx 1243 Aug 1 2013 07:04:02 +00:00 packages.conf
15502 -rw- 1243 Aug 1 2013 11:53:51 +00:00 packages.conf.bad
Switch#del flash:packages.conf
Delete filename [packages.conf]?
Delete flash:/packages.conf? [confirm]
Switch#software expand running switch 1 to flash:

[1]: Copying package files
[1]: Package files copied

Switch#show boot

Current Boot Variables:
BOOT variable does not exist
Boot Variables on next reload:
BOOT variable = flash:packages.conf;
Manual Boot = no
Enable Break = no
Switch#reload
Reload command is being issued on Active unit, this will reload the whole stack
Proceed with reload? [confirm]
如果上述復原方法失敗,3850 系列交換器提供一種陷阱門方法,可用來復原系統。終端機必須連線至執行 TFTP 伺服器之交換器的管理連接埠。從 CCO 下載有效的映像檔,並將其儲存在 TFTP 伺服器的根目錄中。
交換器可能會停滯在 switch: 提示。但是,如果您處於啟動迴圈中,請使用交換器正面的模式按鈕來打破迴圈:按住該按鈕大約 10 秒,交換器便會打破迴圈並停在 switch: 提示。
完成以下步驟,即可執行緊急復原:
switch: set IP_ADDR 192.0.2.123/255.255.255.0
switch: set DEFAULT_ROUTER 192.0.2.1
switch: ping 192.0.2.1
