3600#copy tftp: slot1:

Address or name of remote host []? 171.68.173.10

Source filename []? c3640-i-mz.122-7b.bin

Destination filename [c3640-i-mz.122-7b.bin]?

Accessing tftp://171.68.173.10/c3640-i-mz.122-7b.bin...

Erase slot1: before copying? [confirm]n !--- 您在此规定"n" ，因为没有足够的可用内存。

3600#

请使用 dir slot1: 命令来检查镜像是否已复制入slot1。在下文中你可以看见新的镜像 c3640-i-mz.122-7b.bin 已经复制入PCMCIA slot1:中

3600#dir slot1:

Directory of slot1:/

2 -rw- 3748760 c3640-i-mz.120-22.bin

3 -rw- 5996844 c3640-i-mz.122-7b.bin

步骤 5：将引导说明设定为开启时加载新镜像

经由TFTP复制好镜像之后，您可能需要通知路由器启动时加载什么镜像。

检查当前引导说明

此时，新的镜像正在slot1中。您需要设定路由器以新的镜像进行启动。默认设置是，路由器以首个可用镜像进行启动（当配置中没有引导说明时，将启用默认值）。

3600#show running-config

Building configuration...

Current configuration:

!

version 12.0

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

!

hostname 3600

!

boot system flash slot1:c3640-i-mz.120-22.bin

!

ip subnet-zero

!

以下命令出现在配置的开头。在我们上文的实例中，显示路由器boot system命令配置为 boot system flash slot1:c3640-i-mz.120-22.bin。
