[ZT]Cisco 3750交换机配置无故丢失，恢复一例

一台WS-C3750G-24T交换机，在SI技术人员配置离开后，加电开机，居然提示：

Would you like to terminate autoinstall? [yes]: no

— System Configuration Dialog —

Would you like to enter the initial configuration dialog? [yes/no]: no

奇怪，他们走时明明是”Write”过啊，怎么又要进行初始配置？检查配置文件情况：

Switch#dir

Directory of flash:/

2 -rwx 1383 Mar 1 1993 00:15:06 +00:00 config.old

3 -rwx 6206799 Mar 1 1993 00:27:44 +00:00 c3750-i5-mz.122-25.SE.bin

4 -rwx 2724 Mar 1 1993 00:17:43 +00:00 vlan.dat.renamed

5 drwx 192 Mar 1 1993 00:05:17 +00:00 c3750-ipbase-mz.122-25.SEB4

364 -rwx 5861 Mar 1 1993 00:16:56 +00:00 config.text.renamed

365 -rwx 5 Mar 1 1993 00:16:56 +00:00 private-config.text.renamed

15998976 bytes total (2672640 bytes free)

Switch#

几个配置文件都被加上了.renamed后缀名。真是见鬼，这不太像人工所为，上网G了一把，也有不少人有过此经历，看来最大的可能是在开机时，碰到前面板上的”MODE”按键了。知道原因了，就得开始解决问题。

1、先查看一下今天的配置内容是否健在：

Switch#more flash:/config.text.renamed

!

version 12.2

no service pad

还好，全都健在。

2、把名字改回去：

Switch#rename flash:vlan.dat.renamed vlan.dat

Destination filename [vlan.dat]?

Switch#rename flash:/config.text.renamed config.text

Destination filename [config.text]?

Switch#rename flash:/private-config.text.renamed private-config.text

Destination filename [private-config.text]?

Switch#dir

Directory of flash:/

365 -rwx 5 Mar 1 1993 00:16:56 +00:00 private-config.text

15998976 bytes total (2672640 bytes free)

Switch#

3、把配置文件COPY到start-up-config，然后重启。

Switch#copy flash:config.text nvram:startup-config

Destination filename [startup-config]?

[OK]

5861 bytes copied in 0.151 secs (38815 bytes/sec)

Switch#reload

Proceed with reload? [confirm]

4、重启恢复正常。
