Cisco3750堆叠交换机升级IOS

虽然现在Cisco 3750产品已经快out了,但还是记录下Cisco 3750堆叠交换机升级IOS的方法,也基本适用于其它3750系列交换机。

主要命令

show switch
dir flash1:
dir flash2:
delete flash1:/xxx/old_ios.bin        ##如果flash空间不足,需先删除旧IOS文件
delete flash2:/xxx/old_ios.bin 
 
copy tftp: flash1:/xxx/new_ios.bin       ##导入新的IOS文件
copy tftp: flash2:/xxx/new_ios.bin
dir flash1:
dir flash2:
boot system switch all flash:/xxx/new_ios.bin      ##设置交换机boot启动项
show boot
write
reload

实例说明

1.检查交换机现有ios版本

2.检查交换机堆叠信息

C3750#show switch

Switch/Stack Mac Address : 001e.7afe.7b80
                                           H/W   Current
Switch#  Role   Mac Address     Priority Version  State

3       Member 001b.90a8.4b80     5      0       Ready       
 

3.检查交换机剩余空间和ios文件路径

C3750#dir flash1:

Directory of flash:/

    2  -rwx        2596   Dec 9 2014 14:56:30 +08:00  vlan.dat
    3  -rwx       41133  Mar 27 2015 16:57:01 +08:00  config.text
    4  -rwx           5  Mar 27 2015 16:57:01 +08:00  private-config.text
    5  drwx         192   Mar 1 1993 08:06:45 +08:00  c3750-ipbase-mz.122-35.SE5

15998976 bytes total (6326272 bytes free)
 

C3750#dir flash1:/c3750-ipbase-mz.122-35.SE5

Directory of flash:/c3750-ipbase-mz.122-35.SE5/

    6  -rwx     7175078   Mar 1 1993 08:05:45 +08:00  c3750-ipbase-mz.122-35.SE5.bin
    7  drwx        4224   Mar 1 1993 08:06:08 +08:00  html

15998976 bytes total (6326272 bytes free)

 

4.删除旧ios、检查

注:如果交换机flash剩余空间充足,就不用删除旧ios。

C3750#delete flash1:/c3750-ipbase-mz.122-35.SE5/c3750-ipbase-mz.122-35.SE5.bin
Delete filename [/c3750-ipbase-mz.122-35.SE5/c3750-ipbase-mz.122-35.SE5.bin]?
Delete flash:/c3750-ipbase-mz.122-35.SE5/c3750-ipbase-mz.122-35.SE5.bin? [confirm]

C3750#dir flash1:/c3750-ipbase-mz.122-35.SE5   

Directory of flash:/c3750-ipbase-mz.122-35.SE5/

    7  drwx        4224   Mar 1 1993 08:06:08 +08:00  html
  508  -rwx         598   Mar 1 1993 08:06:45 +08:00  info

同样方法删除flash2,flash3

C3750#dir flash2:/c3750-ipbase-mz.122-35.SE5
Directory of flash2:/c3750-ipbase-mz.122-35.SE5/

    7  drwx        4224   Mar 1 1993 08:06:02 +08:00  html
  508  -rwx         598   Mar 1 1993 08:06:40 +08:00  info

15998976 bytes total (13501440 bytes free)
C3750#dir flash3:/c3750-ipbase-mz.122-35.SE5
Directory of flash3:/c3750-ipbase-mz.122-35.SE5/

    5  drwx        4224   Mar 1 1993 08:08:23 +08:00  html
  506  -rwx         600   Mar 1 1993 08:08:57 +08:00  info

15998976 bytes total (13501440 bytes free)
可以看到三台交换机均已删除旧ios,剩余flash空间充足。

 

5.上传ios到交换机

C3750#copy tftp: flash1:

Address or name of remote host []? 192.168.196.188
Source filename []? c3750-ipbasek9-mz.122-55.SE8.bin
Destination filename [c3750-ipbasek9-mz.122-55.SE8.bin]?
Accessing tftp://192.168.196.188/c3750-ipbasek9-mz.122-55.SE8.bin...
Loading c3750-ipbasek9-mz.122-55.SE8.bin from 192.168.196.188 (via Vlan255): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 12103244 bytes]

12103244 bytes copied in 183.426 secs (65984 bytes/sec)

同样的方法上传新ios到flash2、flash3

C3750#copy tftp: flash2:             
C3750#copy tftp: flash3:
 

6.检查各个交换机的ios文件

C3750#dir flash1:

Directory of flash:/

    2  -rwx        2596   Dec 9 2014 14:56:30 +08:00  vlan.dat
    3  -rwx       41133  Mar 27 2015 16:57:01 +08:00  config.text
    4  -rwx           5  Mar 27 2015 16:57:01 +08:00  private-config.text
    5  drwx         128  Apr 22 2015 12:28:24 +08:00  c3750-ipbase-mz.122-35.SE5
    6  -rwx    12103244  Apr 22 2015 12:41:45 +08:00  c3750-ipbasek9-mz.122-55.SE8.bin

15998976 bytes total (1397760 bytes free)

C3750#dir flash2:
Directory of flash2:/

    2  -rwx        2596   Dec 9 2014 14:56:30 +08:00  vlan.dat
    3  -rwx       41133  Mar 27 2015 16:57:03 +08:00  config.text
    4  -rwx           5  Mar 27 2015 16:57:03 +08:00  private-config.text
    5  drwx         128  Apr 22 2015 12:32:01 +08:00  c3750-ipbase-mz.122-35.SE5
    6  -rwx    12103244  Apr 22 2015 12:46:17 +08:00  c3750-ipbasek9-mz.122-55.SE8.bin

15998976 bytes total (1397760 bytes free)
C3750#dir flash3:
Directory of flash3:/

    2  -rwx        2596   Dec 9 2014 14:56:30 +08:00  vlan.dat
    3  drwx         128  Apr 22 2015 12:32:17 +08:00  c3750-ipbase-mz.122-35.SE5
  507  -rwx           5  Mar 27 2015 16:57:03 +08:00  private-config.text
    4  -rwx    12103244  Apr 22 2015 12:50:08 +08:00  c3750-ipbasek9-mz.122-55.SE8.bin
  509  -rwx       41133  Mar 27 2015 16:57:03 +08:00  config.text

15998976 bytes total (1397760 bytes free)

 

7.更改交换机boot启动项并检查

C3750#configure terminal
C3750(config)#boot system switch all flash:c3750-ipbasek9-mz.122-55.SE8.bin
 
验证boot设置:

C3750#show boot
BOOT path-list      : flash:c3750-ipbasek9-mz.122-55.SE8.bin
Config file         : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break        : no
Manual Boot         : no
HELPER path-list    :

Config file         : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break        : no
Manual Boot         : no
HELPER path-list    :

Auto upgrade        : no
Auto upgrade path   :
——————-
Switch 3
——————-
BOOT path-list      : flash:c3750-ipbasek9-mz.122-55.SE8.bin
Config file         : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break        : no
Manual Boot         : no
HELPER path-list    :

Auto upgrade        : no
Auto upgrade path   :

可以看到三台交换机boot启动项均已配置成功,下次启动会从新ios载入
 

8.保存

C3750#write
Building configuration…
[OK]
 

9.重启

C3750#reload
Proceed with reload? [confirm]

User Access Verification

 
Username:
 
等待5-10分钟。。。
 

10.重新登录,查看ios版本

可以看到三台交换机的ios已经由原来的 12.2(35)SE5  成功升级为 12.2(55)SE8

 

11.最后检查

通过一些show命令和ping上联和下联设备等方式检查升级后的交换机是否正常工作。
 
 
至此,堆叠交换机的ios升级已全部成功完成。
