设定新的引导说明
现在设定路由器以新的镜像进行启动。请发出以下命令来设定boot system参数：
boot system flash slot#:{imagename} (imagename = name of the new Cisco IOS software image)
3600#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
3600(config)#boot system flash slot1:c3640-i-mz.122-7b.bin
3600(config)#^Z
3600#write memory
3d01h: %SYS-5-CONFIG_I: Configured from console by vty0
Building configuration...
3600#
通过发出show version命令来检验是否正在使用 config-register 0x2102 。假如是不同的设定，您可以通过在配置模式中发出以下命令进行改变：
3600#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
3600(config)#config-register 0x2102
3600(config)#^Z
改变了config - register之后，将在下一次重新加载时变化起作用。
步骤6：重新启动路由器以加载新镜像
为使路由器运行新的Cisco IOS软件镜像，您需要重新加载路由器。请确保您已发出 copy running-config starting-config 命令或者 write memory 命令来保存配置。
3600#write memory
3d01h: %SYS-5-CONFIG_I: Configured from console by vty0 (127.0.0.11)
Building configuration...
3600#reload
步骤 7: 检验升级
当路由器开启后，请通过发出 show version 命令确保您当前运行的是新版本。
3640#show version
