步骤：1、在PC机上安装并运行TFTP server，TFTP server的地址就是PC机的IP地址，192.168.0.89/16（TFTP）2、通过Console线配置路由器Fa0/0端口的IP地址，保证和PC机的IP在一个网段即可，192.168.0.100/16（Route）3、验证PC机和路由器互相能ping通

设置路由器fa0/0端口IP地址Router>enableRouter#conf tRouter(config)#int fa0/0Router(config-if)#ip address 192.168.0.100 255.255.0.0Router(config-if)#no shutdown

Ping PC机验证连通情况Router#ping 192.168.0.89Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.0.89, timeout is 2 seconds:.!!!!Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/4 ms

查看Flash的名称Router#show version....System p_w_picpath file is "flash:c2600-i-mz.122.17a.bin"....

备份Flash文件到TFTP serverRouter#copy flash tftpSource filename []? c2600-i-mz.122.17a.binAddress or name of remote host []? 192.168.0.89Destination filename [c2600-i-mz.122.17a.bin]?

备份NVRAM文件到TFTP serverr2600#copy startup-config tftpAddress or name of remote host []? 192.168.0.89Destination filename [r2600-confg]? r2600-config!!399 bytes copied in 0.052 secs (7673 bytes/sec)
