cisco catalyst3550 IOS升级

Question

本帖最后由 xy-coordinate 于 2010-11-26 13:05 编辑

准备工作：
一台PC、一台cisco catalyst3550
TFTP服务器版软件
12.4EMI增强版IOS

3550简单配置一下，目的能与TFTP服务器（PC机器）通讯

PC机器IP设置：192.168.1.2/24
3550 vlan1 IP 192.168.1.1/24
保证 在同一个网段就行了！

1、查看原来IOS情况

catalyst3550#dir
Directory of flash:/

    3  -rwx         344   Jan 01 1970 00:01:44  system_env_vars

2、备份原来的IOS
tar打包上传

catalyst3550#archive tar /create tftp://192.168.1.2/c3550.tar flash: c3550-i9q3l2-mz.121-13.EA1a

在TFTP服务器（PC机器），TFTP目录下可以找到c3550.tar文件，这就是整个IOS的备份！  

注意：如果上面命令中不是输入tftp://192.168.1.2/c3550.tar，直接是c3550.tar，则生成.tar文件在flash中

可以用命令上传到TFTP服务器
3550# copy flash tftp
Address or name of remote host []: 192.168.1.2    //注释：TFTP server IP
Source filename []: c3550.tar    //注释：源文件名，flash在前，说明从c3550 flash上传TFPT服务器
Destination filename [c3550.tar]: c3550.tar     //注释：目标文件名

如果只想更新.bin文件，源文件名输入“完全.bin文件路径”，就把.bin文件上传TFTP server备份保存！！！

3、从TFTP服务器上（PC机器）下载新IOS文件 12.4EMI

由于考虑到设备flash大小不够大，所以要把现有的IOS刪除掉，以便新的IOS顺利上到flash。
12.4EMI 文件大约11,581,440 字节

catalyst3550#format flash:
format operation may take a while. Continue? [confirm]
format operation will destroy all data in "flash:".  Continue? [confirm]
有点慢，等待……
flashfs[1]: 0 files, 1 directories
flashfs[1]: 0 orphaned files, 0 orphaned directories
flashfs[1]: Total bytes: 7741440
flashfs[1]: Bytes used: 1024
flashfs[1]: Bytes available: 7740416
flashfs[1]: flashfs fsck took 6 seconds.
format of flash complete

catalyst3550#sh flash

Directory of flash:/

No files in directory

首先，把c3550-ipservicesk9-tar.122-44.SE.tar放到TFTP server（PC机器）TFTP目录中
然后，3550上，下载并且解压tar包
catalyst3550#archive tar /xtract tftp://192.168.1.2/c3550-ipservicesk9-tar.122-44.SE.tar flash:
TFTP有点慢，继续等待……

也可以用命令
A 下载
3550# copy tftp flash
Address or name of remote host []: 192.168.1.2
Source filename []: c3550-ipservicesk9-tar.122-44.SE.tar
Destination filename [c3550-ipservicesk9-tar.122-44.SE.tar]:

注意：tftp在前，表示源在TFTP；flash在前，表示源在flash
这样就很好地区分上传、下载了！！！

B 解压tar包
catalyst3550#archive tar /xtract c3550-ipservicesk9-tar.122-44.SE.tar flash:

下载解压完毕后，查看文件大小
catalyst3550#dir
Directory of flash:/

    2  -rwx         285   Mar 01 1993 01:31:07  info
    3  drwx         128   Mar 01 1993 01:37:38  c3550-ipservicesk9-mz.122-44.SE
  317  -rwx         285   Mar 01 1993 01:38:41  info.ver

15998976 bytes total (4562432 bytes free)

如果只想更新.bin文件，只需把c3550-ipservicesk9-mz.122-44.SE.bin下载到flash中

4、设置boot启动文件

catalyst3550#sh boot
BOOT path-list:       flash:c3550-i9q3l2-mz.121-13.EA1a/c3550-i9q3l2-mz.121-13.EA1a.bin
Config file:          flash:/config.text
Private Config file:  flash:/private-config.text
Enable Break:         no
Manual Boot:          no
HELPER path-list:     
NVRAM/Config file
      buffer size:    393216
查看，还是原来的启动文件

设置boot为新IOS文件
首先，查看新IOS文件.bin在什么位置
catalyst3550#dir
Directory of flash:/

    2  -rwx         285   Mar 1 1993 01:31:07 +00:00  info
    3  drwx         128   Mar 1 1993 01:37:38 +00:00  c3550-ipservicesk9-mz.122-44.SE

好好学习，天天向上

Answer 4

如何更新3550的SMI到EMI?
步骤：

一、单纯更新ISO（文件后缀名bin）
1.del 原来的IOS文件(用dir falsh: 检查)
2.copy tftp flash:
    然后就下一步&下一步就copy 完成
3.改变开机的ios 路径：
   conf t
   boot systyem  ios文件名
4.check 开机路径
   sh boot
5. reload

二、连同网页一起更新进去
拿到的IOS是tar文件，里面要有html目录
1.del 原来的IOS文件(用dir falsh: 检查)
2.执行以下命令
   archive download-sw /overwrite tftp://192.168.1.2/c3550-ipservicesk9-tar.122-50.SE1.tar
3.改变开机的ios 路径：
   conf t
   boot systyem  ios文件名
4.check 开机路径
   sh boot
5.reload

Answer 9

注意事项：
1、路径和目标文件不一致问题
在升级过程中一定要小心，在敲命令行的时候特别要仔细，特别是在改动启动路径的时候，如果启动路径和flash里面的IOS不相同的话，是启动不了的。
解决方法：
A 在switch模式下，查看系统启动路径的全称
Interrupt within 5 seconds to abort boot process.
Boot process failed...
The system is unable to boot automatically.  The BOOT
environment variable needs to be set to a bootable
image.
switch: set
ASSEMBLY_REVISION_NUM=B0
BOOT=flash:c3550-smi.bin
MAC_ADDR=00:04:4D:72:87:C0
MODEL_NUM=WS-C3524-XL-EN
MODEL_REVISION_NUM=A0
MOTHERBOARD_ASSEMBLY_NUM=73-3904-11
MOTHERBOARD_SERIAL_NUM=FAB0445F1YR
POWER_SUPPLY_PART_NUM=34-0851-02
POWER_SUPPLY_SERIAL_NUM=NONE
SYSTEM_SERIAL_NUM=FAA0446W0XD
switch:

B 查看flash下IOS的完全名称
switch: dir flash:
Directory of flash:/
2    -rwx  1645824   <date>               c35550-smi.bin
3    -rwx  1564      <date>               config.text
4    drwx  6784      <date>               html
111  -rwx  1367      <date>               01
112  -rwx  600       <date>               vlan.dat
114  -rwx  290       <date>               env_vars
936960 bytes available (2675712 bytes used)
switch:
C 把flash里面的IOS的名称改成和boot里面的一致

switch: rename flash:c35550-smi.bin flash:c3550-smi.bin
switch:
switch:
switch: dir flash:
Directory of flash:/
2    -rwx  1645824   <date>               c3550-smi.bin
3    -rwx  1564      <date>               config.text
4    drwx  6784      <date>               html
111  -rwx  1367      <date>               01
112  -rwx  600       <date>               vlan.dat
114  -rwx  290       <date>               env_vars
936960 bytes available (2675712 bytes used)
switch:
D 重新启动设备

switch: reset
Are you sure you want to reset the system (y/n)?y
System resetting...

2、IOS文件损坏或者其他导致IOS损坏不能正常启动
如果在升级过程中出现断电或者其他原因导致IOS没有完全写入flash中，但是flash中旧的IOS又已经被删除掉了。
解决方法：
A 只能采用超级终端用Xmodem来把IOS传到设备
超級终端的设置采用默认设置就行了！
B 在switch模式下执行采用xmodem
（很长时间，打印40分钟）
C 重启设备
传完后，重启设备就ok啦。

3、启动路径不完全，导致设备不能正常启动
在升级过程中的最后一步，修改启动路径时，如果把路径写错了，导致设备不能正常启动。
解决方法：
比如本来正确的是boot system flash:c3550-smi.bin，结果写成了boot  system c3550-smi.bin
A 用set命令查看设备当前运行的路径

switch: set
ASSEMBLY_REVISION_NUM=B0
BOOT=c3550-smi.bin
MAC_ADDR=00:04:4D:72:87:C0
MODEL_NUM=WS-C3524-XL-EN錯誤！未找到圖形專案表。
MODEL_REVISION_NUM=A0
MOTHERBOARD_ASSEMBLY_NUM=73-3904-11
MOTHERBOARD_SERIAL_NUM=FAB0445F1YR
POWER_SUPPLY_PART_NUM=34-0851-02
POWER_SUPPLY_SERIAL_NUM=NONE
SYSTEM_SERIAL_NUM=FAA0446W0XD
switch:
B 用set命令修改BOOT路径

switch: set boot flash:c3550-smi.bin
switch: set
ASSEMBLY_REVISION_NUM=B0
BOOT=flash:c3550-smi.bin
MAC_ADDR=00:04:4D:72:87:C0
MODEL_NUM=WS-C3524-XL-EN
MODEL_REVISION_NUM=A0
MOTHERBOARD_ASSEMBLY_NUM=73-3904-11
MOTHERBOARD_SERIAL_NUM=FAB0445F1YR
POWER_SUPPLY_PART_NUM=34-0851-02
POWER_SUPPLY_SERIAL_NUM=NONE
SYSTEM_SERIAL_NUM=FAA0446W0XD
switch:

C 重启启动就OK了！
