CISCO 3750升级IOS实例

单位有一台CISCO3750,不能支持OSPF,为使他能支持OSPF,需进 行IOS升级,详细步骤如下:

1、配置计算机与交换机连通 本处将计算机与交换机直连,本地计算机IP地址设为10.1.1.1/31,与交换机1号以太网口相连。 R1#configure terminal R1(config)#interface f

单位有一台CISCO3750,不能支持OSPF,为使他能支持OSPF,需进 行IOS升级,详细步骤如下:

1、配置计算机与交换机连通

本处将计算机与交换机直连,本地计算机IP地址设为10.1.1.1/31,与交换机1号以太网口相连。

R1#configure terminal

R1(config)#interface fastEthernet 1/0/1

R1(config-if)#no switchport

R1(config-if)#ip address 10.1.1.2 255.255.255.252

2、架设tftp环境(本次以3CDaemon为例)

将3CDaemon安装在本地计算机C盘根目录下,运行3CDaemon.EXE并进行相关设置。

3、查看原IOS版本等信息

R1#show version

4、下载新IOS文件

将新IOS下载保存(文件名为c3750-ipservicesk9-mz.122-50.SE3.bin,文件大小为11.6M),并将该文件拷贝至 tftp指定目录。

5、查看原IOS文件位置及相关信息

R1#show boot

R1#dir

Directory of flash:/

2 -rwx 5 Mar 1 1993 02:10:54 +00:00 private-config.text

3 -rwx 1612 Apr 1 1993 22:19:01 +00:00 vlan11.dat

4 -rwx 796 Mar 1 1993 06:16:26 +00:00 vlan.dat

5 drwx 192 Mar 1 1993 00:06:42 +00:00 c3750-ipbase-mz.122-35.SE5

509 -rwx 3427 Mar 1 1993 02:10:54 +00:00 config.text

15998976 bytes total (6364160 bytes free)

R1#cd c3750-ipbase-mz.122-35.SE5(注意文件名区分大小写)

R1#dir

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

6 -rwx 7175078 Mar 1 1993 00:05:41 +00:00 c3750-ipbase-mz.122-35.SE5.bin

7 drwx 4224 Mar 1 1993 00:06:04 +00:00 html

508 -rwx 598 Mar 1 1993 00:06:42 +00:00 info

15998976 bytes total (6364160 bytes free)

剩余空间不到10M,而新IOS文件超过10M,所以需先将原IOS文件删除以释放FLASH空间。

删除前先备份原IOS文件。

R1#copy /c3750-ipbase-mz.122-35.SE5 /c3750-ipbase-mz.122-35.SE5.bin tftp

Address or name of remote host []? 10.1.1.1

Destination filename [c3750-ipbase-mz.122-35.SE5.bin]?

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

7176192 bytes copied in *** secs (***bytes/sec)

R1#delete 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]

R1#dir

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

7 drwx 4224 Mar 1 1993 00:06:04 +00:00 html

508 -rwx 598 Mar 1 1993 00:06:42 +00:00 info

15998976 bytes total (13539328 bytes free)

剩余空间已超过新IOS文件大小,可以进行升级。

6、将新IOS文件上传至交换机flash(本处拷贝至根目录下)

R1#copy tftp flash

Source filename [/c3750-ipbase-mz.122-35.SE5/c3750-ipbase-mz.122-35.SE5.bin]? /c3750-ipbase-mz.122-35.SE5/c3750-ipbase-mz.122-35.SE5.bin

Address or name of remote host []? 10.1.1.1

Destination filename [c3750-ipbase-mz.122-35.SE5.bin]?

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

7175078 bytes copied in 63.770 secs (112515 bytes/sec)

7、设置启动IOS为新IOS:

R1(config)#boot system flash:c3750-ipservicesk9-mz.122-50.SE3.bin

R1(config)#exit

R1#wr

Building configuration...

然后重启后有效

R1#reload
