搭載Supervisor 720且執行Cisco IOS軟體12.2(17)SX之前的Catalyst 6500的密碼復原程式
簡介
本檔案介紹如何在搭載Supervisor 720的Catalyst 6500系列交換器(執行Cisco IOS®系統軟體(版本低於12.2(17)SX)上復原密碼。
12.2(17)SX之前的Cisco IOS軟體版本中的程式不同是因為思科錯誤ID CSCec36997(僅限註冊客戶)(在sup720-native上復原密碼會導致交換器處理器(SP)崩潰)。 當您的交換機受此錯誤影響時，您在進入RP ROMMON後，大約有10秒的時間將配置暫存器更改為0x2142。在這10秒之後，交換機將重新載入，並進行Software Forced reload。但是，如果在崩潰之前將配置暫存器更改為此值，則配置暫存器將在重新載入後生效，您可以繼續執行其餘過程。
必要條件
需求
本文件沒有特定需求。
採用元件
本檔案適用於執行Cisco IOS軟體版本12.2(17)SX之前的Supervisor 720型系統。如果您的Supervisor 720執行Cisco IOS軟體版本12.2(17)SX或更新版本，請參閱執行Cisco IOS系統軟體的Catalyst 6000/6500系列交換器的密碼復原程式檔案。
概觀
由於硬體不同，執行Cisco IOS的Catalyst 6500/6000上的開機順序與Cisco 7200系列路由器上的不同。重新通電後，SP將啟動。大約25-60秒後，它將控制檯所有權轉移到路由處理器(RP(MSFC))。 RP繼續載入捆綁的軟體映像。在SP將控制檯的控制權交給RP之後，立即按Ctrl-Break至關重要。如果您傳送中斷序列太快，則最終會進入SP的ROMMON，而不是您應該處於的位置。在主控台上看到以下訊息後，傳送中斷順序：
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
在此之後，口令恢復與普通路由器相同。
註：從現在起，運行Cisco IOS軟體的Catalyst 6500系列交換機稱為路由器。
慣例
如需文件慣例的詳細資訊，請參閱思科技術提示慣例。
逐步程序
由於Cisco IOS作業系統在交換機上運行，因此該交換機被配置為路由器。密碼復原程式與Cisco 7200系列路由器執行的步驟相同。例外情況是，您必須等待大約25至60秒才能開始中斷順序。
-
將終端機或具有終端模擬的PC連線到路由器的控制檯埠。使用以下終端機設定：
9600 baud rate No parity 8 data bits 1 stop bit No flow control
電纜規格檔案中介紹了所需的控制檯電纜規格。模組安裝指南中提供了有關如何連線到控制檯埠的說明。連線到控制檯埠 — 僅Supervisor Engine部分提供了有用的資訊。
-
如果仍然可以訪問路由器，請發出show version命令，並記錄配置暫存器的設定。它通常為0x2102或0x102。按一下此處檢視show version命令的輸出示例。
-
如果您無法訪問路由器（由於登入或TACACS密碼丟失），可以安全地假設您的配置暫存器設定為0x2102。
-
關閉電源，然後在電源開關的幫助下開啟路由器電源。
-
在RP獲得控制檯埠的控制權後，立即按終端鍵盤上的Break。在執行Cisco IOS的Catalyst 6500上，SP首先啟動。然後將控制權交給RP。RP獲得控制後，啟動中斷順序。當您看到此訊息時，RP已控制主控台連線埠。（在看到以下消息之前不要啟動中斷順序）：
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
由於Cisco錯誤ID CSCec36997(僅供註冊客戶使用)（sup720-native上的密碼恢復會導致在SP上崩潰），您大約需要10秒才能完成步驟6，然後交換器就會崩潰。
如果Break按鍵順序不起作用，請參閱密碼復原期間的標準Break按鍵順序組合以瞭解其他按鍵組合。
-
在rommon 1>提示符下鍵入confreg 0x2142，以便在不載入配置的情況下從快閃記憶體啟動。
-
交換器因軟體強制崩潰而崩潰：

-
在每個設定問題後鍵入no，或按Ctrl-C跳過初始設定過程。
-
在Router>提示時鍵入enable。您處於enable模式。將顯示Router#提示。
-
發出configure memory或copy start running命令將非易失性RAM(NVRAM)複製到記憶體中非常重要。不要發出configure terminal命令。
-
發出write terminal或show running命令。這些命令顯示路由器的配置。在此配置中，您將在所有介面下看到shutdown命令。這意味著所有介面當前均已關閉。您會看到加密或未加密格式的密碼。
-
發出configure terminal命令以進入全域性配置模式並進行更改。現在提示符為hostname(config)#。
-
在全域性配置模式下發出enable secret<password >以更改啟用密碼。
-
發出config-register 0x2102命令，或是在全域性配置模式下步驟2中記錄的值(Router(config)#)，將配置值設回其原始值。
-
更改任何虛擬終端密碼（如果存在）：
Router(config)#line vty 0 4 Router(config-line)#password cisco Router(config-line)#^Z Router#
-
在正常使用的每個介面上發出no shutdown命令。發出show ip interface brief命令以檢視介面及其當前狀態的清單。您必須處於啟用模式(Router#)才能執行show ip interface brief命令。以下是一個介面的範例：
Router#show ip interface brief Interface IP-Address OK?

Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface fastEthernet 3/1 Router(config-if)#no shutdown Router(config-if)#exit Router(config)# <do other interfaces as necessary...>
-
按Ctrl-Z離開配置模式。提示符現在為hostname#。
-
發出write memory或copy running startup命令以提交更改。
輸出示例
此處的示例顯示了實際的密碼恢復過程。此範例是在Catalyst 6500系列交換器的幫助下建立。從show version和show module命令開始，檢視此示例中使用的元件。
