运行 12.2(17)SX 之前版本的 Cisco IOS 软件且配有 Supervisor 720 的 Catalyst 6500 的口令恢复过程
简介
本文档介绍如何在运行 Cisco IOS® 系统软件（版本低于 12.2(17)SX）的 Catalyst 6500 系列交换机（带有 Supervisor 720）上恢复口令。
12.2(17)SX之前的Cisco IOS软件版本的操作步骤不同的原因是Cisco Bug ID CSCec36997(仅限注册客户)(在sup720上恢复口令会导致交换机处理器(SP)崩溃。 当您的交换机遇到此Bug时，在进入RP ROMMON后，您大约有10秒的时间将配置寄存器更改为0x2142。在这10秒后，交换机将重新加载软件强制重新加载。但是，如果您在崩溃前将配置寄存器更改为此值，则此值将在重新加载后生效，并且您可以继续执行剩余过程。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档适用于运行版本低于 12.2(17)SX 的 Cisco IOS 软件且基于 Supervisor 720 的系统。如果您的Supervisor 720运行Cisco IOS软件版本12.2(17)SX或更高版本，请参阅运行Cisco IOS系统软件的Catalyst 6000/6500系列交换机的口令恢复程序文档。
概述
由于硬件不同，运行 Cisco IOS 的 Catalyst 6500/6000 的启动顺序与 Cisco 7200 系列路由器的启动顺序不同。在为机箱重新通电后，SP 将启动。大约 25-60 秒后，它将控制台所有权转交给路由处理器 (RP (MSFC))。 RP 继续加载捆绑的软件映像。请务必在 SP 将控制台控制权转交给 RP 之后立即按 Ctrl-Break。如果您太早发送中断序列，则您会进入 SP 的 ROMMON 模式，这不是您想要的模式。请在控制台上显示以下消息后发送中断序列：
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
在这之后，口令恢复过程与普通路由器一样。
注意：从此开始，运行Cisco IOS软件的Catalyst 6500系列交换机称为路由器。
规则
有关文件规则的更多信息请参见“ Cisco技术提示规则”。
分步过程
由于交换机上运行 Cisco IOS 操作系统，因此交换机的配置方式与路由器相同。口令恢复过程的步骤与 Cisco 7200 系列路由器相同。不同之处是在开始发送中断序列之前，您必须多等待 25-60 秒。
-
将终端或带终端仿真功能的 PC 连接到路由器的控制台端口。使用以下终端设置：
9600 baud rate No parity 8 data bits 1 stop bit No flow control
电缆规格文档中描述了所需的控制台电缆规格。有关如何连接到控制台端口的说明，请参阅模块安装指南。连接到控制台端口 - 仅 Supervisor 引擎部分提供了有用的信息。
-
如果您仍需要访问路由器，请发送 show version 命令，并且记录配置寄存器设置。它通常为0x2102或0x102。单击此处查看show version命令的示例输出。
-
如果您无法访问路由器（由于丢失登录口令或 TACACS 口令），则将配置寄存器设置为 0x2102 较安全。
-
使用电源开关先关闭路由器电源，然后再将其打开。
-
在 RP 获得控制台端口的控制权后，立即按终端键盘上的 Break。在运行 Cisco IOS 的 Catalyst 6500 上，SP 先启动。然后，它将控制权转交给 RP。在 RP 获得控制权后，启动中断序列。当显示此消息时，RP 已获得控制台端口的控制权。（在看见以下消息前，请不要发送中断顺序信号）：
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
由于Cisco Bug ID CSCec36997（仅限注册客户）（在sup720-native上恢复口令会导致SP崩溃），因此在交换机崩溃之前，您有大约10秒的时间完成步骤6。
-
请在 rommon 1> 键入 confreg 0x2142，以便在不装载配置的情况下从闪存处引导。
-
交换机因软件强制崩溃而崩溃：
rommon 1 > 00:00:41: %SYS-SP-3-LOGGER_FLUSHED: System was paused for 00:00:00 to ensure co. 00:00:41: %SYS-SP-2-INTSCHED: 't_idle' at level 7 -Process= "SCP Download Process", ipl= 7, pid= 57 -Traceback= 4013991C 401232B4 402827F4 40282994 40283010 405CB010 402A9858 4013C 00:00:41: %SYS-SP-2-INTSCHED: 't_idle' at level 7 -Process= "SCP Download Process", ipl= 7, pid= 57 -Traceback= 4013991C 401232B4 402827F4 40282994 40283010 405CB010 402A9858 4013C 00:00:41: %SYS-SP-2-INTSCHED: 't_idle' at level 7 -Process= "SCP Download Process", ipl= 7, pid= 57 -Traceback= 4013991C 401232B4 402827F4 40282994 40283010 405CB010 402A9858 4013C 00:00:41: %OIR-SP-6-CONSOLE: Changing console ownership to switch processor *** System received a Software forced crash *** signal= 0x17, code= 0x24, context= 0x4269f6f4 PC = 0x401370d8, Cause = 0x3020, Status Reg = 0x34008002路由器重新启动。但是，由于配置寄存器设置为0x2142，因此它会忽略其保存的配置。如果您看到路由器配置仍然存在（仍旧是以前的主机名），则表明在崩溃之前配置寄存器未及时更改为0x2142。如果出现这种情况，请重新启动（步骤 4）。 如果配置寄存器已正确地更改为 0x2142，则重新加载后，会显示初始配置问题。
-
在每个设置问题后面键入 no，或者按 Ctrl-C 跳过初始设置程序。
-
在 Router>提示符处键入 enable。现在您处于启用模式，且显示了 Router# 提示符。
-
发出 configure memory 或 copy start running 命令将非易失性 RAM (NVRAM) 复制到内存中，此操作很重要。请不要发出 configure terminal 命令。
-
发出 write terminal 或 show running 命令。这些命令将显示路由器的配置。在此配置中，shutdown 命令显示在所有接口下面。这意味着所有接口当前已关闭。此外，口令都采用加密或未加密格式。
-
发出 configure terminal 命令以进入全局配置模式并进行更改。当前的提示是 hostname(config)#。
-
在全局配置模式下发出 enable secret < password > 以更改启用口令。
-
发出 config-register 0x2102 命令或者在全局配置模式 (Router(config)#) 第 2 步记录的值，将配置值设置回最初值。
-
更改所有虚拟终端口令（如果存在虚拟终端）：
Router(config)#line vty 0 4 Router(config-line)#password cisco Router(config-line)#^Z Router#
-
在正常使用的每个接口上发出 no shutdown 命令。发出 show ip interface brief 命令查看接口及其当前状态的列表。您必须在启动模式 (Router#) 才能执行 show ip interface brief 命令。这里给出一个接口例子：
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...>
-
按下 Ctrl-z 离开配置模式。当前的提示 hostname#。
-
发出 write memory 或 copy running startup 命令以提交更改。
