更新Cisco2960L固件

1.把更新包放到TFTP服務器目錄下
2.連接交換機的電腦設置一個地址。

3.設置交換機上連接電腦的端口的地址，要在同一個網段

Xier-Server-SW02(config-if)# int g0/29 Xier-Server-SW02(config-if)#no switchport ##不關閉交換端口，無法設置地址 Xier-Server-SW02(config-if)#ip address 172.16.100.3 255.255.255.0 Xier-Server-SW02(config-if)#do ping 172.16.100.2 ##ping一下電腦地址看看通不通 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.16.100.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 3/3/3 ms Xier-Server-SW02(config-if)#end

4.復制電腦上的更新包到交換機上

Xier-Server-SW02#copy tftp:c2960l-universalk9-mz.152-7.E4.bin flash: ## 這里復制一下文件名Address or name of remote host []? 172.16.100.2 ##輸入一下電腦的地址 Destination filename [c2960l-universalk9-mz.152-7.E4.bin]? ##直接回車 Accessing tftp://172.16.100.2/c2960l-universalk9-mz.152-7.E4.bin...
