7609升级引擎板学习笔记
7609的引擎板虽然为一个IOS启动,但采用仍是的二层 SP+三层RP Native-IOS 结构
而且对SPRP分别可以设置寄存器的值,设定不同的启动方式
对于二层SP
(1)在Rommon模式下不能查看当前值,但可以设置寄存器值,
设置寄存器的方法如下:
启动7609,按CtrlBreak会进入rommon状态;
输入confreg 0x2102, 输入sync保存,输入 reset重启 
注:如果SP0x2100,则启动时必须要进入rommon模式
(2)如果要查看当前引擎二层SP值,可以native IOS下执行remote command switch show _ver
NJ-A-ZN-SR7609-1#remote command switch show ver

(2)修改RP的值,常用于交换机密码恢复
运行Native IOSCatalyst6000系列交换机的启动顺序跟其它交换机不一样,因为它们的硬件结构不一样。当你打开交换机开关之后,交换机处理器SPSwitch Processor)首先启动,然后在很短的时间之内(大概25秒钟)SP会将控制口(console)交给路由处理器RP/MSFC(Route Processor),路由处理器继续引导系统文件。要进行密码恢复应该在console命令大全SPconsole交给RP之后按 Ctrl-brk,如果你太早中断启动过程,则会进入SP ROMMON状态,这不是你要的状态。要确定什么时候中断启动过程,可以在看见下面的信息时候按Ctrl-brk 中断启动过程:
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
1. 首先通过console线从console端口进入交换机。
2. 关闭交换机的电源,然后再打开交换机电源。
3. SP将控制权交给RP之后,在终端上输入Break。注意,在没有看见下面的信息之前不要中断系统启动:
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
4. rommon 1>提示符下输入confreg 0x2142 
5. rommon 2> 提示符下输入 reset
6. setup中输入 no或者按Ctrl-C 跳过setup过程。
7. Router>提示符下输入enable
8. 运行copy start running将旧的配置文件拷贝的内存中。
9. 运行 enable secret 修改密码。
10. 、运行config-register 0x2102 修改寄存器的值。
如果要查看主备引擎的三层RP值,可以执行
NJ-A-ZN-SR7609-1#show redundancy
Redundant System Information :
------------------------------
      Available system uptime = 12 hours, 41 minutes
Switchovers system experienced = 1
              Standby failures = 0
        Last switchover reason = user initiated
                Hardware Mode = Duplex
    Configured Redundancy Mode = rpr-plus
    Operating Redundancy Mode = rpr-plus
              Maintenance Mode = Disabled
                Communications = Up
Current Processor Information :
-------------------------------
              Active Location = slot 5
        Current Software state = ACTIVE
      Uptime in current state = 11 hours, 9 minutes
