Cisco2960交换机下载IOS

1、按照下图搭建网络拓扑：

2、配置PC的IP地址：

3、使用超级终端连接交换机

4、配置交换机地址：

Switch>en
Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int vlan 1
Switch(config-if)#ip add 192.168.1.2 255.255.255.0
Switch(config-if)#no sh

Switch(config-if)#
%LINK-5-CHANGED: Interface Vlan1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up

5、测试交换机与PC的连通性

Switch#ping 192.168.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 0/0/0 ms

可以连通

6、查看flash IOS版本及大小

Switch#dir flash:
Directory of flash:/

    1  -rw-     4670455          <no date>  2960-lanbasek9-mz.150-2.SE4.bin

64016384 bytes total (59345929 bytes free)

将文件名2960-lanbasek9-mz.150-2.SE4.bin复制，等下会用到

7、确认PC开启TFTP服务

如果是物理环境，SecureCRT软件有TFTP服务，在菜单栏Transfer下

8、通过TFTP把IOS下载到PC

Switch#copy flash: tftp: 
Source filename []? 2960-lanbasek9-mz.150-2.SE4.bin
Address or name of remote host []? 192.168.1.1
Destination filename [2960-lanbasek9-mz.150-2.SE4.bin]? 

Writing 2960-lanbasek9-mz.150-2.SE4.bin...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 4670455 bytes]

4670455 bytes copied in 0.063 secs (5960122 bytes/sec)

9、验证PC本地文件
