簡介
本檔案介紹使用指令行介面(CLI)升級Cisco Catalyst 3750系列交換器上軟體映像的步驟。
必要條件
需求
下載軟體之前，請參閱Catalyst 3750、3560和2970交換器(Cisco IOS®版本12.2(25)SEB和更高版本)的版本說明中的以下各節，瞭解重要資訊：
採用元件
本檔案中的資訊是根據以下硬體版本：
-
WS-C3750G-12S交換機
-
WS-C3750G-24TS交換機
註：您可以替換任何堆疊式Catalyst 3750系列交換機。
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。
慣例
查詢軟體版本和功能集
具有Cisco IOS®軟體版本名稱的目錄將Cisco IOS映像儲存為bin檔案。該目錄將映像儲存在系統主機板快閃記憶體裝置(flash:)上。子目錄包含您進行Web管理所需的檔案。
您可以使用 show version 能看到交換器上執行的軟體版本。顯示屏的第二行顯示版本。
註：雖然 show version 輸出總是顯示交換機上運行的軟體映像，此顯示結尾顯示的型號名稱為出廠配置。此映像是IP Base映像(以前稱為標準多層映像(SMI))或IP Services映像(以前稱為增強型多層映像(EMI))。如果升級軟體映像，此名稱不會更改。
您還可以使用 dir filesystem: privileged EXEC 指令。此命令顯示已儲存在快閃記憶體中的任何其他軟體映像的目錄名稱。
決定要將交換器升級到的Cisco IOS軟體版本之前，必須執行以下操作：
-
閱讀特定Cisco IOS軟體版本的版本說明。請參閱Cisco Catalyst 3750系列交換器 — 版本說明。
-
請參閱Bug Toolkit（僅限註冊客戶）和Cisco Catalyst 3750系列交換器 — 現場通知。
尋找Catalyst 3750交換器的優先順序值
優先順序值決定堆疊中的主要交換器。優先順序值可為 1 到 15。預設優先順序值為 1。思科建議將最高的優先順序值指定給您希望當作堆疊主機的交換器。在本範例中，主要交換器的優先順序值是15。如需詳細資訊，請參閱建立和管理Catalyst 3750交換器堆疊。

升級可能需要您釋放更多空間。此要求取決於您在Flash中儲存了多少映像。您可以刪除舊映像/目錄以釋放此空間。
3750系列交換器堆疊Cisco IOS升級 — 自動（.tar映像）
本節提供用於設定本文件中所述功能的資訊。
本節中的步驟將合併的tar檔案複製到交換機。您將檔案從TFTP伺服器複製到交換器並擷取檔案。您可以下載映像檔案並替換當前映像，也可以保留當前映像。
註：對於交換機堆疊，archive download-sw 和archive upload-sw 特權EXEC命令只能通過堆疊主目錄使用。下載到堆疊主要成員的軟體映像會自動下載到其餘堆疊成員。因此，您必須登入到主交換機才能執行此升級。
逐步說明
若要下載軟體，請完成以下步驟：
步驟1
使用本文檔的「決定使用哪些檔案」一節可識別您要下載的映像型別和功能集。
步驟2
若要為Catalyst 3750交換器下載較舊版本的IP Services映像或IP Base映像檔案，請按一下「Archived Catalyst 3750 Software」。若要取得授權並下載加密軟體檔案，請按一下「Catalyst 3750強式加密(3DES)軟體」。
註：低於Cisco IOS軟體版本12.1(19)EA1c的Cisco IOS軟體版本包括引導載入程式升級。首次載入新軟體時，引導載入程式可能需要長達1分鐘的時間進行升級。開機載入器升級時，請勿重新啟動交換器。
步驟3
將映像複製到工作站上適當的TFTP目錄，並確保TFTP伺服器具有正確的配置。
如需詳細資訊，請參閱此版本軟體組態指南的附錄B。
步驟4
透過主控台連線埠或Telnet作業階段登入交換器，然後進入啟用模式。
步驟5
若要檢視目前的版本，請發出 show version 指令。

3750系列交換器堆疊Cisco IOS升級 — 手動（.tar映像）
本文的前一節說明如何使用 archive download-sw 指令。您也可以手動逐個交換器升級Cisco IOS，且無需斷開堆疊纜線。該方法主要分為三個步驟：
-
將.tar映像從TFTP伺服器複製到主交換器。
-
將.tar映像解壓到交換機的所有Flash檔案系統中。
-
配置引導變數。
其 archive download-sw 命令執行Cisco IOS自動升級過程中的所有三個步驟。您也可以在手動Cisco IOS升級中執行以下三個步驟。逐步部分顯示如何升級到Cisco IOS軟體版本12.2(25)SEE1的示例。此範例中的交換器堆疊包含三台交換器。交換機1是主交換機，交換機2和3是成員交換機。
逐步說明
步驟1 — 下載.tar映像
您需要確保主交換機的快閃記憶體中有足夠的可用空間。主交換機的空間量必須是.tar映像檔案大小的兩倍。要儲存.tar檔案，以及儲存您下一步在步驟2中抽取的.tar檔案的內容，需要此空間。例如，如果.tar映像大小為10 Mb，則至少需要有20 Mb的可用空間。
3750-stack#copy tftp: flash: Address or name of remote host []? 10.10.10.10 Source filename []? c3750-advipservicesk9-tar.122-25.SEE1.tar Destination filename [c3750-advipservicesk9-tar.122-25.SEE1.tar]?

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!--- Output is suppressed.
步驟2 — 提取.tar映像
將.tar映像解壓到快閃記憶體檔案系統中的所有交換機。其 archive tar /xtract 命令建立一個目錄，並在新建立的目錄下提取檔案。
以下是命令語法的範例：
3750-stack#archive tar /xtract
請完成以下子步驟：
-
將.tar檔案擷取到switch1的快閃記憶體中。
3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar flash1: extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/grn_vertlines_bott.gif (957 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/red.gif (147 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/print.gif (625 bytes) !--- Output is suppressed.
-
將.tar檔案擷取到switch2的快閃記憶體中。
3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar flash2: extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/grn_vertlines_bott.gif (957 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/red.gif (147 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/print.gif (625 bytes) !--- Output is suppressed.
-
將.tar檔案擷取到switch3的快閃記憶體中。
3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar flash3: extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/grn_vertlines_bott .gif (957 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/red.gif (147 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/print.gif (625 bytes) !--- Output is suppressed.
步驟3 — 配置引導變數
將.tar檔案擷取到快閃記憶體後，需要設定開機變數以指向新的Cisco IOS。您需要尋找擷取.bin檔案的路徑。
3750-stack#dir

3750系列交換器堆疊Cisco IOS升級 — 手動（.bin映像）
3750交換器堆疊可以通過Web裝置管理員或CLI進行管理。如果使用CLI管理交換器，則不需要.tar映像。本節介紹使用.bin映像進行Cisco IOS升級。假設您已使用Cisco IOS映像設定3750交換器堆疊。本節介紹如何在3750交換器堆疊中複製和升級新的Cisco IOS。
註：命令 archive download-sw 和 archive upload-sw 僅適用於.tar映像檔案，而不適用於.bin映像檔案。
此範例說明在Catalyst 3750交換器堆疊上升級到Cisco IOS軟體版本12.2(25)SEE2的逐步程式。Catalyst 3750交換器堆疊中有兩台交換器，而Cisco IOS映像位於TFTP伺服器172.22.1.165上。此輸出會顯示此堆疊中的堆疊成員和主要成員：
Switch#show switch

Switch# Role Mac Address Priority State
--------------------------------------------------------
1 Member 0015.63f6.b700 5 Ready
*2 primary 0015.c6c1.3000 10 Ready
逐步說明
步驟1 — 下載.bin映像
請參閱軟體下載 — Cisco Catalyst 3750軟體，並找到您要下載的映像。Catalyst 3750的軟體下載中心包含每套功能集和版本的兩組Cisco IOS映像。一組只包含副檔名為.bin的Cisco IOS映像檔案。另一組包含Cisco IOS映像以及副檔名為.tar的基於Web的裝置管理器。
第2步 — 檢驗可用記憶體
您可以分別驗證兩台交換器的快閃檔案系統中的可用記憶體，如以下範例輸出所示：

疑難排解
本節提供的資訊可用於對組態進行疑難排解。
從TFTP伺服器傳輸映像失敗或已損壞的Cisco IOS映像
如果您發現從TFTP伺服器進行的映像傳輸連續失敗，請參閱解決常見映像安裝問題。本文提供TFTP伺服器已知問題的解決方案。
您收到Error_Bad_Mzip錯誤訊息
Cisco IOS映像損毀或.tar檔案透過Xmodem上傳時會顯示此錯誤。為了解決問題，請完成以下步驟：
-
透過Xmodem將.bin檔案上傳到交換器。
-
將啟動路徑設定為正確的檔名。
-
重新載入交換器。
-
檢查影象檔案大小是否正確。
如果映像檔案大小不正確，請嘗試再次下載映像檔案。
請參閱這些檔案以檢查復原程式：

完成以下步驟以識別並解決此問題：
-
確保能夠從交換機ping TFTP伺服器IP地址。
-
驗證您的TFTP伺服器是否正常工作，如果可能，請嘗試其他TFTP伺服器。
-
如果快閃記憶體中有任何舊資訊目錄，則將其刪除。
-
如果錯誤訊息繼續顯示，請格式化快閃記憶體並重新載入交換器。格式化後，交換機可引導至ROMMON模式。如果交換機啟動到ROMMON模式，則使用Xmodem恢復交換機。
堆疊中的交換器無法開機新映像（版本不相符）
Cisco IOS升級後，任何一台或多台交換機都不會使用新映像啟動。或者，將交換器新增至目前堆疊時，且新增的交換器的Cisco IOS軟體版本與當前交換器堆疊不同，則新交換器將不能使用。3750交換器堆疊具有自動升級功能，該功能預設啟用。此功能可讓交換器堆疊自動升級新增交換器上的Cisco IOS。有時，此自動升級無法升級新增交換器的Cisco IOS。將交換器新增至目前堆疊時，會顯示以下訊息序列。

注意：必須啟用自動升級功能，才能在版本不匹配(VM)模式下升級交換機。預設情況下，自動升級已啟用。您可以檢視自動升級的狀態，網址為 show boot 顯示中的特權執行命令和自動升級行。您可以通過以下方式禁用自動升級： no boot auto-copy-sw 堆疊主交換器上的全域組態指令。如需詳細資訊，請參閱瞭解自動升級和自動建議。
有三種不同的方法可以解決版本不相符的問題：
方法1 - .tar映像
升級軟體映像與 archive copy-sw 特權EXEC命令。此指令將軟體映像從目前的堆疊成員複製到具有不相容軟體的堆疊成員。受影響的交換器會自動重新載入，並將堆疊作為功能完整的成員加入。
此輸出顯示 archive copy-sw 指令:
3750_Stack#archive copy-sw ?
/destination-system specify destination system to receive software
/force-reload Unconditionally reload system after successful sw
upgrade
/leave-old-sw Leave old sw installed after successful sw upgrade
/no-set-boot do not update BOOT setting on systems after installing
sw
/overwrite OK to overwrite an existing image
/reload Reload system (if no unsaved config changes) after
successful sw upgrade
/safe Always load before deleting old version
1 copy software from system 1
2 copy software from system 2
3 copy software from system 3
-
在/destination-system destination-stack-member-number中，指定運行映像檔案的源需要複製到的堆疊成員編號。如果不指定堆疊成員編號，則預設情況下會將執行中的映像檔複製到所有堆疊成員。
-
指定 /force-reload 可在成功下載軟體映像後無條件強制系統重新載入。如果不希望使用/force-reload，請使用reload slot switch_member_number 手動重設更新的堆疊成員，以使此組態變更生效。
-
針對source-stack-member-number，指定複製執行中映像檔案的堆疊成員編號。堆疊成員編號的範圍為1到9。
-
如果在重新載入期間收到超訂用系統日誌消息，則發出archive copy-sw /overwrite /destination-system 命令以使用下載的軟體映像覆蓋快閃記憶體中的軟體映像。
以下是 archive copy-sw 指令:
-
此
archive copy-sw指令將目前執行的Cisco IOS映像從交換器1複製到3750交換器堆疊上的交換器3。archive copy-sw /overwrite /destination-system 3 1
-
重新載入交換器成員3。
reload slot 3
方法2 - .tar映像
如果使用裝置管理器來管理交換器堆疊，則可以使用這種方法。將.tar映像擷取到新增交換器的快閃檔案系統中。假設交換器上已具有.tar映像。如果沒有提供，您可以從頁面下載Cisco Catalyst 3750軟體，並使用TFTP複製到交換器。軟體下載網站。

此錯誤消息的原因是 archive 命令用於.tar檔案，不能與.bin檔案一起使用。若要使用.bin 檔案升級，請使用 copy 指令。
使用不同的功能集升級Cisco IOS軟體
預設情況下，Cisco Catalyst 3750系列允許您在升級至較新Cisco IOS版本時變更功能集。
Error: The image in the archive which would be used to upgrade Error: system number [dec] does not support the same feature set.
為了克服此問題，請使用標誌 allow-feature-upgrade 當您執行 archive-download-sw 指令。
