背景資訊

簡介

本檔案介紹在具有備援Supervisor Engine(在Supervisor Engine上執行Cisco Catalyst作業系統(CatOS)，而在多層交換器功能卡(MSFC)上執行Cisco IOS)或本機模式(在Supervisor Engine和MSFC上執行Cisco IOS的備援Supervisor Engine的Catalyst 600/6500系列交換器上升級軟體映像的逐步程式。如需CatOS和Cisco IOS系統軟體之間差異的詳細資訊，請參閱適用於Catalyst 6500/6000交換器的CatOS轉換為Cisco IOS。

註：在VSS環境中升級Cisco IOS本機映像時，本文檔也適用。

在下列情況下，必須升級軟體映像：

• 您希望在網路中實施新軟體版本中可用的新功能。

• 您想安裝交換機上運行的當前軟體版本不支援的新線卡。

• 已知錯誤會影響交換器，該錯誤會在下一個軟體版本中解決。

Supervisor冗餘

Catalyst 6500系列交換器允許備援Supervisor Engine在主Supervisor Engine發生故障時接管功能，以便支援容錯功能。冗餘Supervisor Engine的型別必須與同一型號功能卡相同，這樣才能支援冗餘。安裝兩個Supervisor Engine時，第一個聯機的Supervisor Engine將成為活動模組。第二個Supervisor Engine進入備用模式。所有管理和網路管理功能(例如簡易網路管理通訊協定(SNMP)、指令行介面(CLI)主控台、Telnet、跨距樹狀目錄通訊協定(STP)、Cisco探索通訊協定(CDP)和VLAN中繼線通訊協定(VTP))都在作用中Supervisor Engine上處理。在備用Supervisor Engine上，控制檯埠處於非活動狀態。冗餘Supervisor引擎可熱插拔。切換到冗餘Supervisor Engine後，系統繼續使用相同的配置運行。

Cisco IOS軟體和Catalyst OS都支援在Catalyst 6500機箱內部署冗餘管理引擎，以實現元件級冗餘。但是，Supervisor Engine備援的運作模式在Cisco IOS軟體和CatOS之間有所不同。

注意：冗餘始終處於啟用狀態，無法禁用。當交換機上安裝了兩個Supervisor引擎時，即會啟用冗餘，並且交換機根據其擁有的映像型別決定使用哪種特定的冗餘模式。兩個管理引擎上運行的Cisco IOS和功能集必須相同，才能實現SSO冗餘。

混合模式

在CatOS中，管理引擎冗餘的基礎是高可用性功能。此功能允許具有雙管理引擎的系統在活動和備用Supervisor引擎之間同步協定狀態。如果發生活動Supervisor故障，則備用Supervisor將接管系統操作，並獲取交換機上運行的協定的準確最新狀態資訊。這允許管理引擎故障切換在一到三秒內發生，並且不需要第2、3和4層協定的網路重新收斂。從路由器的角度看，MSFC引擎可設定為備援，也可設定為混合軟體。

在Cisco Catalyst OS 8.5版之前，Catalyst OS高可用性功能預設處於禁用狀態。備選方案稱為快速切換。快速切換功能是高可用性功能的前身。因此，當高可用性被禁用或軟體版本不支援時，Supervisor Engine就會採用切換機制。為了縮短切換時間，此功能將跳過Supervisor Engine發生故障時通常發生的一些事件。具體地，快速切換機制允許每個線卡跳過相應的軟體下載和診斷的一部分，這些通常為系統重新初始化的一部分。切換仍包括重新啟動所有協定（第2層及更高層）以及重置所有埠。

使用預設設定的切換效能結果大約需要28秒，加上協定重新啟動所需的時間。高可用性消除了此限制。高可用性允許活動Supervisor Engine與備用Supervisor Engine通訊。這會保持功能協定狀態同步。Supervisor Engine之間的同步允許備用Supervisor Engine在出現故障時進行接管。

預設情況下，在Cisco Catalyst 6500系列交換機上，主用和備用Supervisor Engine上的Catalyst OS軟體映像必須相同。如果在系統啟動過程中，兩個Supervisor映像的版本不同，則活動Supervisor Engine會將其當前啟動映像下載到待命Supervisor Engine。作用中Supervisor Engine的NVRAM組態也會在Supervisor Engine之間同步。

Catalyst OS高可用性功能的第二部分稱為版本控制。這取決於在雙Supervisor Engine配置中啟用的高可用性功能。這允許不同的但相容的映像在活動和備用Supervisor Engine上運行，從而禁用預設的Supervisor映像同步進程。此功能主要用於簡化涉及兩個Supervisor Engine時的軟體升級程式。

具有冗餘管理引擎/MSFC組合的混合系統可以選擇在同一機箱中有兩個活動MSFC（稱為雙路由器模式）。在此配置中，熱待命路由器協定(HSRP)在兩個活動MSFC之間內部配置。使用Cisco IOS軟體時，備用MSFC不能完全運行。因此，無法在兩個MSFC之間運行內部HSRP。通過Cisco IOS軟體，路由處理器冗餘(RPR)、路由處理器冗餘Plus(RPR+)或狀態切換無中斷轉發(NSF/SSO)模式支援從Cisco Catalyst 6500到網路中其他路由器的外部HSRP。

如需詳細資訊，請參閱設定備援連線。

本地模式

Catalyst 6500上的Cisco IOS軟體支援RPR(也稱為增強型高系統可用性(EHSA)、RPR+、NSF/SSO)，以及具有狀態化切換(SRM/SSO)的單路由器模式。在此操作模型中，一對Supervisor/MSFC完全可操作，而另一對處於備用模式。

show module命令會列出作用中及備用管理引擎。兩對之間存在心跳消息以確保快速故障檢測。具有RPR或RPR+的Supervisor引擎之間沒有狀態協定冗餘。SSO冗餘模式在Cisco IOS中的Supervisor Engine之間提供狀態協定冗餘，在功能上與Cisco Catalyst OS高可用性冗餘模式等同。

在Cisco IOS軟體中，Supervisor和MSFC各自負責不同的功能和通訊協定（第2層和第3層）。但是，系統取決於兩個引擎的可用性以便正確操作。在RPR/RPR+/SSO模式下，Supervisor或MSFC發生故障會導致從活動Supervisor切換到備用Supervisor/MSFC。

注意：在混合模式下，如果一個MSFC發生故障，Supervisor Engine可以保持完全運行。MSFC故障不一定導致管理引擎切換，但只能導致MSFC故障切換。這樣可建立一個交叉模式，其中主用原則功能卡(PFC)和執行Catalyst OS的交換處理器(SP)在一個插槽中完全運作，而路由處理器(RP)/MSFC在另一個插槽中完全運作。

本節概述具有RPR、RPR+、NSF/SSO和SRM/SSO的管理引擎冗餘特性：

• RPR - Cisco IOS軟體中引入的第一個冗餘操作模式。在RPR模式下，啟動配置和引導暫存器在活動管理引擎和備用管理引擎之間同步，備用管理引擎未完全初始化，並且活動管理引擎和備用管理引擎之間的映像不需要相同。切換後，備用Supervisor自動變為活動狀態，但它必須完成引導過程。此外，所有線卡都已重新載入，硬體也已重新程式設計。RPR切換時間為2分鐘或更長時間。

• RPR+ — 對RPR的增強，其中備用管理引擎完全啟動，並且線卡在切換時不會重新載入。將在主用管理引擎和備用管理引擎之間同步運行的配置。還會執行從RPR繼承的所有同步活動。同步在切換之前完成，當備用裝置變為活動狀態時將使用同步到備用裝置的資訊，以最大限度地減少停機時間。主用管理引擎和備用管理引擎之間沒有同步鏈路層或控制平面資訊。切換後介面可能會發生跳轉，需要重新對硬體內容進行程式設計。RPR+切換時間為30秒或更長。實際的故障切換時間取決於配置的大小和複雜性。

• NSF/SSO - Cisco IOS軟體和CatOS都支援使用SSO的NSF。這些功能的應用位置和方式與首先在Cisco IOS中部署的這些功能的更高級形式有關。SSO擴展了RPR+功能，以便在出現管理引擎故障時提供第2層協定的透明故障切換。SSO對於第2層協定是有狀態的。在切換過程中維護PFC和分散式轉發卡(DFC)硬體表。這允許在第2層和第4層進行透明故障切換。NSF與SSO協同工作，以確保切換後第3層的完整性。它允許遇到活動Supervisor故障的路由器繼續沿已知路由轉發資料包，同時恢復和驗證路由協定資訊。通過允許對等安排在故障轉移時進行恢復的重新啟動機制，可以繼續進行此類轉發。這可避免不必要的路由擺動和網路不穩定。使用NSF/SSO時，故障切換時間為0到3秒。

• SRM/SSO — 交換機通電後，帶有SSO的SRM將在兩個Supervisor引擎之間運行。首先啟動的Supervisor Engine會成為活動的Supervisor Engine。MSFC和PFC完全可操作。備援Supervisor Engine和MSFC的組態與作用中Supervisor Engine和MSFC的組態完全相同。在活動MSFC和備援MSFC上建立進程（如路由協定）。冗餘Supervisor Engine完全初始化和配置，縮短了切換時間。當冗餘Supervisor Engine聯機時，活動Supervisor Engine會檢查冗餘Supervisor Engine的映像版本。如果冗餘Supervisor Engine上的映像與活動Supervisor Engine上的映像不匹配，則使用RPR模式。如果活動Supervisor Engine或MSFC發生故障，則冗餘Supervisor Engine和MSFC將變為活動狀態。帶SSO的SRM支援第2層單播流量的0到3秒的切換時間。

  註：只有Supervisor Engine 720和Supervisor Engine 32支援帶SSO的SRM。

軟體升級

本節提供在含備援Supervisor Engine的Catalyst 6500系列交換器上升級軟體映像的相關資訊。

注意：此過程可能會影響資料流量。思科建議您在scheduled maintenance（計畫維護）時段內執行此過程。

注意：使用Cisco CLI Analyzer獲取本節所用命令的詳細資訊。只有註冊思科使用者才能訪問內部思科工具和資訊。

本地模式

本節提供在含在本機模式下執行的備援Supervisor引擎的Catalyst 6500系列交換器上升級軟體映像的相關資訊。

對於此過程，建議兩個Supervisor Engine都可以使用控制檯連線。活動Supervisor Engine上的控制檯埠處於活動狀態，而備用Supervisor Engine上的控制檯埠處於非活動狀態。

註：本文檔使用的軟體映像僅供示例使用。將映像替換為交換機環境中使用的映像。

完成以下步驟，升級作用中及待命Supervisor Engine上的Cisco IOS軟體映像：

1. 建立到活動Supervisor Engine的控制檯連線，並驗證映像版本是否在Supervisor Engine上運行。

2. 檢查Supervisor Engine模組的狀態。

   Cat-6509#show module

   show module命令輸出中待命Supervisor Engine的模組狀態在本機Cisco IOS的不同備援模式下是不同的：

   • RPR — 狀態顯示冷。

     冷冗餘是指冗餘系統傳統上提供的恢復能力。當備份或備用系統與其保護的系統之間不維護狀態資訊時，冗餘系統處於冷狀態。

   • RPR+ — 狀態顯示熱。

     熱備援是指冷備系統之外的恢復能力。在這種情況下，冗餘系統已部分準備就緒。但是，系統沒有主系統為立即接管而知道的所有狀態資訊。必須確定一些其他資訊，或者從流量或對等網路裝置中收集這些資訊，才能處理資料包轉發。

   • SSO — 狀態顯示熱。

     熱冗餘是指冗餘系統完全準備好處理主系統流量的恢復程度。大量狀態資訊被儲存，因此網路服務是連續的，並且在發生故障切換時，對通訊流的影響最小或為零。

3. 從作用中Supervisor Engine驗證備援模式狀態。

   Cat-6509#

   註:Supervisor Engine 32的預設冗餘操作模式是具有相同映像版本的SSO，如果安裝了不同的映像版本，則為RPR。

4. 驗證兩個Supervisor Engine的啟動變數。

   Cat-6509#show bootvar
   BOOT variable = disk0:s3223-ipbasek9-mz.122-18.SXF.bin,12;
   CONFIG_FILE variable does not exist
   BOOTLDR variable = 
   Configuration register is 0x2102
   
   Standby is up
   Standby has 983040K/65536K bytes of memory.
   
   Standby BOOT variable = disk0:s3223-ipbasek9-mz.122-18.SXF.bin,12;
   Standby CONFIG_FILE variable does not exist
   Standby BOOTLDR variable = 
   Standby Configuration register is 0x2102

5. 作為最佳實踐記錄您的控制檯會話。

   如果您需要排除故障，日誌使您能夠捕獲會話記錄並將日誌與本文檔中的步驟進行比較。

   例如，在「超級終端機」中，選擇「傳輸」>「擷取文字」以記錄主控台作業階段。

   如需詳細資訊，請參閱將終端機連接到 Catalyst 交換器上的主控台連接埠。

6. 發出copy start tftp 命令以備份配置。

   如果備份組態，則升級後檔案可作為參考。請參閱在Catalyst交換器上管理軟體映像和使用組態檔，以取得更多有關使用copy start tftp 命令備份組態檔的資訊。

7. 驗證升級所需的Cisco IOS映像(s3223*)是否位於Supervisor Engine bootflash(sup-bootdisk: 和sulatedatessup-bootdisk: )上，或位於兩個Supervisor Engine的CompactFlash卡(disk0:和sulatedatesk0:)上。

   63971328 bytes total (8736768 bytes free)
   Cat-6509#

   如果您在Supervisor bootflash(sup-bootdisk: 和sulatesup-bootdisk: )或CompactFlash卡(disk0:和sulateatedisk0:)上沒有用於升級的Cisco IOS映像，請轉至步驟8。如果您已安裝Cisco IOS映像，請轉至步驟9。

8. 僅當Cisco IOS軟體映像(s3223*)不存在於Supervisor Engine bootflash(sup-bootdisk: 和sulatedatessup-bootdisk: )或CompactFlash卡(disk0:和sulatedatedisk0: )上時完成此步驟。步驟7 決定是否需要執行此步驟。

   註：如果CompactFlash以前未使用過，或者使用CatOS軟體演算法格式化過，則需要格式化它。若要格式化Supervisor引擎32上的CompactFlash卡，請發出 format disk0: 命令。您也可以根據需要釋放快閃記憶體裝置上的空間。發出delete sup-bootdisk: filename 或delete disk0: filename 命令以刪除檔案。

   首先發出 copy tftp sup-bootdisk: 命令，然後發出copy tftp sulatesup-bootdisk: 或copy sup-bootdisk: sulatesup-bootdisk: 命令，以便將映像下載到Supervisor Engine引導閃爍。或者，請首先發出 copy tftp disk0: 命令，然後發出copy tftp subsidiatedisk0: 或copy disk0: subsidiatedisk0: 命令將映像下載到CompactFlash卡。

12. 驗證備援狀態。

    註：要在RPR+或SSO冗餘模式下運行，備用和活動Supervisor Engine上的映像版本必須相同。在這些備援模式下，待命Supervisor Engine聯機時，作用中Supervisor Engine會檢查待命Supervisor Engine的映像版本。如果待命Supervisor Engine上的映像與作用中Supervisor Engine上的映像不相符，則軟體會在執行軟體升級時將備援模式設定為RPR，並在軟體升級完成後將其設回SSO。

    插槽5中的舊活動Supervisor Engine會使用新映像重新啟動，並成為備用Supervisor Engine。

    註：從插槽5中的Supervisor Engine啟動切換時，同時在插槽6中建立與Supervisor Engine的控制檯連線。

    註：在軟體升級過程中，操作冗餘模式為RPR。從步驟12所示 show redundancy states命令輸出中可明顯看出這一點。在RPR冗餘中，在切換期間，所有交換模組都重新通電。因此會有幾分鐘的停機時間。在正常切換期間，如果操作冗餘為SSO，則不會重新載入已安裝的交換模組，因為運行的啟動和配置都會從主用管理引擎持續同步到備用管理引擎。新的活動Supervisor引擎使用當前配置。

    在備援Supervisor Engine上升級Cisco IOS軟體的程式已完成。

混合模式

本節提供在含備援Supervisor Engine和在混合模式下執行的MSFC的Catalyst 6500系列交換器上升級軟體映像的相關資訊。

對於此過程，建議兩個Supervisor Engine都可以使用控制檯連線。活動Supervisor Engine上的控制檯埠處於活動狀態，而備用Supervisor Engine上的控制檯埠處於非活動狀態。

註：本文檔使用的軟體映像僅供示例使用。將映像替換為交換機環境中使用的映像。

升級Catalyst作業系統

完成以下步驟，升級作用中及待命Supervisor Engine上的Catalyst OS映像：

1. 建立到活動Supervisor Engine的控制檯連線，並驗證Supervisor Engine上運行的映像版本。

   本檔案使用的影像僅作範例用途。將映像替換為交換機環境中使用的映像。

   註：如果嘗試建立到備用Supervisor Engine的控制檯連線，將顯示以下消息，如下一個代碼示例所示。

   This module is now in standby mode.
   Console is disabled for standby supervisor
   

2. 檢查Supervisor Engine模組的狀態。

   Console> (enable) show module
    
   Mod Slot Ports Module-Type               Model               Sub Status

   !--- Output suppressed.
   
   

   註：在show module命令輸出中，待命Supervisor Engine和MSFC的模塊狀態在CatOS中顯示為待命。

3. 從作用中Supervisor Engine驗證備援模式狀態。

   Console> (enable) show system highavailability 
    
   Highavailability: disabled
   Highavailability versioning: disabled
   Highavailability Operational-status: OFF(high-availability-not-enabled)

   Console> (enable)

   註:CatOS中的預設冗餘操作模式是快速切換。

   注意：高可用性版本控制選項允許您在活動和備用Supervisor Engine上運行不同的軟體映像。預設情況下禁用高可用性版本控制。如果兩個Supervisor Engine的軟體版本不同，或者兩個Supervisor Engine的NVRAM配置不同，並且您未啟用高可用性版本控制，則活動Supervisor Engine會自動將其軟體映像和配置下載到備用Supervisor Engine。

4. 驗證兩個Supervisor Engine的啟動變數。

   Console> (enable) show boot 5
    
   BOOT variable = bootdisk:cat6000-sup32pfc3k8.8-5-6.bin,1;
   CONFIG_FILE variable = bootflash:switch.cfg
   
   Configuration register is 0x2102
   ignore-config: disabled
   auto-config: non-recurring, overwrite, sync disabled
   ROMMON console baud: 9600
   boot: image specified by the boot system commands
   
   Image auto sync is enabled
   Image auto sync timer is 120 seconds
   

   Console> (enable) show boot 6
    
   BOOT variable = bootdisk:BTSYNC_cat6000-sup32pfc3k8.8-5-6.bin,1;
   CONFIG_FILE variable = 
   
   Configuration register is 0x2102
   ignore-config: disabled
   auto-config: non-recurring, overwrite, sync disabled
   ROMMON console baud: 9600
   boot: image specified by the boot system commands
   
   Image auto sync is enabled
   Image auto sync timer is 120 seconds

5. 作為最佳實踐記錄您的控制檯會話。

   如果您需要排除故障，日誌使您能夠捕獲會話記錄並將日誌與本文檔中的步驟進行比較。

   例如，在「超級終端機」中，選擇「傳輸」>「擷取文字」以記錄主控台作業階段。如需詳細資訊，請參閱瞭解與Catalyst交換器上主控台連線埠的終端連線。

6. 在Supervisor Engine上發出copy config tftp 命令，在MSFC上發出copy start tftp 命令，以備份配置。

   如果備份組態，則升級後檔案可作為參考。請參閱在Catalyst交換器上管理軟體映像和使用組態檔，以取得更多有關使用copy config tftp 和copy start tftp 指令備份組態檔的資訊。

7. 確認升級所需的CatOS映像(cat6000-sup32*)位於活動Supervisor引擎bootflash(bootdisk:)或CompactFlash卡(disk0:)上。

   Console> (enable) dir bootdisk:

   如果您在活動的Supervisor Engine bootflash(bootdisk: )或CompactFlash卡(disk0:)上沒有用於升級的CatOS映像，請轉至步驟8。如果已安裝CatOS映像，請轉至步驟9。

8. 僅當CatOS映像(cat6000-sup32*)不在活動Supervisor引擎bootflash(bootdisk: )或CompactFlash卡(disk0:)中時完成此步驟。步驟7確定需要此步驟。

   註：如果CompactFlash以前從未使用過，或者使用Cisco IOS軟體演算法格式化過，則需要對其進行格式化。若要格式化Supervisor引擎32上的CompactFlash卡，請發出 format disk0: 命令。您也可以根據需要釋放快閃記憶體裝置上的空間。發出delete bootdisk: filename 或delete disk0: filename 命令以刪除檔案。

   將新的Catalyst OS軟體映像載入到僅活動Supervisor Engine的bootflash或CompactFlash卡中。發出copy tftp bootdisk: 或copy tftp disk0: 命令，將新映像下載到活動Supervisor Engine bootflash或CompactFlash卡。

   Console> (enable) copy tftp bootdisk:

   Console> (enable)

   註：要將新映像複製到備用Supervisor Engine bootflash或CompactFlash，可以發出copy y/bootdisk:<image.bin> x/bootdisk：或copy y/bootdisk:<image.bin> x/disk0：命令(其中y是活動Supervisor Engine模組編號，x是show module命令輸出中給定的備用Supervisor Engine模組編號)。

   驗證新映像是否已複製到活動Supervisor Engine的bootflash或CompactFlash卡中。

   Console> (enable) dir bootdisk:

9. 將映像自動同步計時器修改為最小值10秒，以加速同步過程。

   預設值為120秒。

   Console> (enable) set boot sync timer 10 
   Image auto sync timer set to 10 seconds.

10. 清除活動Supervisor Engine上的當前啟動變數。

    Console> (enable) clear boot system all
    

    註：清除活動Supervisor Engine上的啟動變數時，不會清除待命Supervisor Engine上的啟動變數。您需要發出clear boot system all 6 命令，以手動清除待命Supervisor Engine上的開機變數。此步驟是可選的。

    Console> (enable)show boot 6
     
    BOOT variable = bootdisk:BTSYNC_cat6000-sup32pfc3k8.8-5-6.bin,1;
    CONFIG_FILE variable = bootflash:switch.cfg

    ROMMON console baud: 9600
    boot: image specified by the boot system commands
    
    Image auto sync is enabled
    Image auto sync timer is 10 seconds

11. 在作用中Supervisor Engine上設定開機變數，以啟動新的Catalyst OS軟體映像。

    Console> (enable) set boot system flash bootdisk:
    cat6000-sup32pfc3k8.8-5-7.bin prepend
    BOOT variable = bootdisk:cat6000-sup32pfc3k8.8-5-7.bin,1;

    Console> (enable) 2006 Oct 19 04:37:55 %SYS-5-SUP_IMGSYNC:

    synchronized bootdisk:cat6000-sup32pfc3k8.8-5-7.bin

    如果CompactFlash以前從未使用過，或者它是使用Cisco IOS軟體演算法格式化的，則需要對其進行格式化。若要格式化Supervisor引擎32上的CompactFlash卡，請發出 format disk0: 命令。您也可以根據需要釋放快閃記憶體裝置上的空間。發出delete bootdisk: filename 或delete disk0: filename 命令以刪除檔案。

    將新的Catalyst OS軟體映像載入到僅活動Supervisor Engine的bootflash或CompactFlash卡中。發出copy tftp bootdisk: 或copy tftp disk0: 命令，將新映像下載到活動Supervisor Engine bootflash或CompactFlash卡。

    Console> (enable) show boot
     
    BOOT variable = bootdisk:cat6000-sup32pfc3k8.8-5-7.bin,1;
    CONFIG_FILE variable = 
    
    Configuration register is 0x2102
    ignore-config: disabled
    auto-config: non-recurring, overwrite, sync disabled
    ROMMON console baud: 9600
    boot: image specified by the boot system commands
    
    Image auto sync is enabled
    Image auto sync timer is 10 seconds

    Console> (enable)

    註：將新映像下載到活動Supervisor Engine時，系統會將新映像複製到檔案系統（在bootflash中或快閃記憶體PC卡中）。由於您已經或沒有將此映像設定為開機映像，因此不會自動將新下載的映像複製到待命Supervisor Engine。為了啟動主用和備用Supervisor Engine之間的同步功能，您必須將這個新下載的映像設定為主用Supervisor Engine上的開機映像。更改引導變數時會發生同步。大約在120秒（此處為10秒）內，在作用中Supervisor Engine上設定為啟動專案的映像會複製到待命Supervisor Engine上的bootflash。這是映像同步。這是Catalyst OS映像檔案的內部TFTP，需要幾分鐘才能完成。

    註：啟動配置中的配置暫存器必須設定為自動啟動(0x2102)。

12. 映像同步後，請確認新的映像位於待命Supervisor Engine上，且已正確設定開機變數。

    Console> (enable) show boot 6
     
    BOOT variable = bootdisk:BTSYNC_cat6000-sup32pfc3k8.8-5-7.bin,
    1;bootdisk:BTSYNC_cat6000-sup32pfc3k8.8-5-6.bin,1;
    CONFIG_FILE variable = bootflash:switch.cfg
    
    Configuration register is 0x2102
    ignore-config: disabled
    auto-config: non-recurring, overwrite, sync disabled
    ROMMON console baud: 9600
    boot: image specified by the boot system commands
    
    Image auto sync is enabled
    Image auto sync timer is 10 seconds

    註：影象檔案的BTSYNC附加在檔名的開頭。這表示它已從作用中Supervisor Engine的開機時映像同步。

    Console> (enable) dir 6/bootdisk:

    235708416 bytes available (20058112 bytes used)

    Console> (enable)

13. 在活動Supervisor Engine上啟用高可用性版本控制。

    啟用高可用性版本控制後，可以在主用和備用Supervisor Engine上擁有兩個不同但相容的映像。活動Supervisor Engine與備用Supervisor Engine交換映像版本資訊並確定映像是否相容以啟用高可用性。如果主用和備用Supervisor Engine未運行相容的映像版本，則無法啟用高可用性。

    註：如果兩個軟體映像不相容，則軟體升級過程會影響系統操作（即大於高可用性切換的一至三秒切換時間），並且不會在Supervisor Engine之間同步NVRAM配置更改。

    註:8.x軟體版本系列中沒有軟體映像版本相容性。這包括主要版本，例如8.1(x)到8.2(x)到8.3(x)等。這也包括子版本，如8.1(1)到8.1(2)、8.2(1)到8.2(2)等。

    Console> (enable) set system highavailability versioning enable
    Image versioning enabled.

    注意：運行新軟體的備用Supervisor Engine變為活動狀態之前，必須啟用版本控制。這允許待命Supervisor Engine在新版CatOS下重新開機，同時保留待命Supervisor Engine。

14. 重設待命Supervisor Engine。

    註：您可以強制進行另一個切換，使備用Supervisor Engine成為活動Supervisor Engine，以便恢復Supervisor Engine的原始角色（它們的活動和備用狀態）。

    在備援Supervisor Engine上升級Catalyst OS軟體的程式已完成。

升級Cisco IOS

完成以下步驟，當交換器以混合模式執行時，升級作用中及待命MSFC上的Cisco IOS映像：

1. 建立到活動Supervisor Engine的控制檯連線並驗證模組狀態。

   Console> (enable) show module
   Mod Slot Ports Module-Type               Model               Sub Status

   !--- Output suppressed.
   
   

   註：在RPR模式下，備用MSFC不會顯示在show module命令輸出中。

2. 發出switch console 命令以存取作用中MSFC。

   Console> (enable) switch console 
   Trying Router-15...
   Connected to Router-15.
   Type ^C^C^C to switch back...

   如果透過Telnet作業階段連線，或如果作用中MSFC位於待命Supervisor Engine上，請發出session 15 或session 16 命令以存取作用中MSFC。

   注意：在混合模式下，活動MSFC可以位於活動或待命Supervisor Engine上。

3. 執行升級之前，請確認在作用中MSFC上執行的映像版本。

                          BOOTLDR = 
           Configuration register = 0x2102

5. 驗證兩個MSFC的啟動變數。

   Router#show bootvar
   BOOT variable = bootflash:c6msfc2a-ipbase_wan-mz.122-18.SXF.bin,1;
   CONFIG_FILE variable = 
   BOOTLDR variable = 
   Configuration register is 0x2102
   
   Standby is up
   Standby has 983040K/65536K bytes of memory.
   
   Standby BOOT variable = bootflash:c6msfc2a-ipbase_wan-mz.122-18.SXF.bin,1;
   Standby CONFIG_FILE variable = 
   Standby BOOTLDR variable = 
   Standby Configuration register is 0x2102
   

6. 發出dir bootflash: 命令，以驗證升級所需的新映像(c6msfc2a*)是否存在於兩個MSFC的bootflash中。

   如果映像不存在，請發出copy tftp bootflash: 或copy tftp subsidiatebootflash: 命令，將新映像複製到活動和備用MSFC引導閃爍。

   注意：如果您有兩個MSFC，則必須將映像單獨下載到備用MSFC bootflash中。映像不會自動下載到備用MSFC。

7. 清除當前引導變數。

   Router#conf t
   Enter configuration commands, one per line.  End with CNTL/Z.
   Router(config)#no boot system flash bootflash:
   c6msfc2a-ipbase_wan-mz.122-18.SXF.bin
   Router(config)#^Z
   Router#write memory
   
   !--- This synchronizes both the active and standby MSFC start-up configurations.
   
   Building configuration...
   [OK]
   Router#show bootvar
   BOOT variable = 
   CONFIG_FILE variable = 
   BOOTLDR variable = 
   Configuration register is 0x2102
   
   Standby is up
   Standby has 983040K/65536K bytes of memory.
   
   Standby BOOT variable =
   Standby CONFIG_FILE variable = 
   Standby BOOTLDR variable = 
   Standby Configuration register is 0x2102

8. 在活動MSFC上，指定在重新載入MSFC時引導新映像。

   Router#conf t
   Enter configuration commands, one per line.  End with CNTL/Z.
   Router(config)#boot system flash bootflash:
   c6msfc2a-ipbase_wan-mz.122-18.SXF6.bin
   

9. 在作用中MSFC上，發出write memory命令，以確保備用MSFC啟動配置也獲取啟動資訊。

   Router(config)#^Z
   Router#write memory
   Building configuration...
   [OK]

10. 驗證新的引導變數設定。

    Router#show bootvar
    BOOT variable = bootflash:c6msfc2a-ipbase_wan-mz.122-18.SXF6.bin,1;
    CONFIG_FILE variable = 
    BOOTLDR variable = 
    Configuration register is 0x2102
    
    Standby is up
    Standby has 983040K/65536K bytes of memory.
    
    Standby BOOT variable = bootflash:c6msfc2a-ipbase_wan-mz.122-18.SXF6.bin,1;
    Standby CONFIG_FILE variable = 
    Standby BOOTLDR variable = 
    Standby Configuration register is 0x2102

    註：啟動配置中的配置暫存器必須設定為自動引導(0x2102)。

11. 在作用中MSFC上發出redundancy reload peer 命令，以重新載入待命MSFC。

    Router#redundancy reload peer 
    Reload peer [confirm]
    Preparing to reload peer
    Router#
    00:12:37: %RF-3-COMMUNICATION: Communication with the peer Route Processor (RP) 
    has been lost.
    00:12:37: %RF-3-SIMPLEX_MODE: The peer Route Processor (RP) has been lost
    00:13:44: %RF-3-VERSION_MISMATCH: Version Info mismatch; Not running same version 
    of software on each Route Processor (RP). Cannot run in SSO mode; 
    will go to RPR mode instead.
    00:13:49: %RF-6-NEGOTIATED_RED_MODE: Negotiated Redundancy MODE is RPR
    00:13:51: %RF-6-DUPLEX_MODE: The peer Route Processor (RP) has been detected
    00:13:51: %RF-3-COMMUNICATION: Communication with the peer Route Processor (RP) 
    has been established.
    
    !--- Output suppressed.
    
    Router#

12. 幾分鐘後發出show redundancy states命令，以確保備用MSFC完全聯機。

    Router#show redundancy states 
           my state = 13 -ACTIVE 
         peer state = 4  -STANDBY COLD 
               Mode = Duplex
               Unit = Primary
            Unit ID = 5
    Redundancy Mode (Operational) = Route Processor Redundancy
    Redundancy Mode (Configured)  = Stateful SwitchOver - SSO
    Redundancy State              = Route Processor Redundancy
    
    !--- Output suppressed.
    
    

    注意：此時您的系統處於RPR模式，而不是SSO模式。這是因為當兩個Supervisor位於不同的映像上時，SSO模式不起作用。當它們在同一映像上重新載入且配置同步後，您將返回到SSO模式。

13. 發出redundancy switch-activity force 命令，以手動切換到備用MSFC。

    Router#redundancy switch-activity force 
    This will reload the active unit and force a switch of activity [confirm]
    Preparing to switch activity
    
    00:16:08: %SYS-5-RELOAD: Reload requested Reload Reason: RF initiated reload.
    
    !--- Output suppressed.
    
    Router-sdby>
    
    !--- The active MSFC reloads and becomes the standby MSFC.
    
    

    活動MSFC重新載入，待命MSFC成為運行新映像的新活動MSFC。

14. 驗證在備用MSFC上運行的映像和冗餘模式。

    注意：您可以強制進行另一個切換，使備用MSFC成為活動MSFC，以便恢復MSFC的原始角色（其活動和備用狀態）。

    在混合模式下升級冗餘MSFC上的Cisco IOS軟體的過程已完成。

將VSS核心從模組化代碼升級到非模組化代碼

在更改軟體的主要版本（模組化到非模組化）時，需要完全升級（機箱重新引導），而不是簡單地遷移到新的模組化版本；例如，從s72033-advipservicesk9_wan-vz.122-33.SXI6.bin升級到s72033-advipservicesk9_wan-mz.122-33.SXI7.bin時。

在機箱上發出show file system命令，以檢視映像位置。

此範例顯示每個機箱中的兩個管理引擎：

VSS#show module switch all

Switch Number:     1    Role:   Virtual Switch Active

----------------------  -----------------------------

Mod Ports Card Type                              Model         Serial No.

--- ----- -------------------------------------- ------------- -----------

  1    5  Supervisor Engine 720 10GE (Active)    VS-S720-10G   SAL1223SVBW

  2    5  Supervisor Engine 720 10GE (RPR-Warm)  VS-S720-10G   SAL1223SVBV

完成以下步驟，將映像升級到VSS中的每個Supervisor:

1. 使用TFTP將映像載入作用中Supervisor（很可能是sup-bootdisk）。

2. 將同一映像複製到活動機箱中的次管理引擎和備用機箱中的兩個管理引擎。舉例來說：

   • copy sup-bootdisk:<image_name> sw1-slot2-sup-bootdisk:

   • copy sup-bootdisk:<image_name> sw2-slot1-sup-bootdisk:

   • copy sup-bootdisk:<image_name> sw2-slot2-sup-bootdisk:

3. 使用dir all 命令驗證映像是否存在。

4. 重寫啟動語句（在show run中找到）以反映新映像。

5. 使用write memory命令以儲存組態。

6. 使用show bootvar命令以驗證啟動順序和配置暫存器。

驗證

目前沒有適用於此組態的驗證程序。

疑難排解

由於IPC錯誤，無法顯示備用堆疊

此錯誤訊息可能會出現在show version 指令輸出中。show bootvar 命令輸出中可能會出現類似錯誤。只有當您擁有冗餘Supervisor Engine且兩者都在不同Cisco IOS軟體版本上運行時，才會顯示此錯誤消息。升級Supervisor Engine中的Cisco IOS軟體版本時，這種情況很常見。
