关于C2811进入系统使用reload命令重启之后不进入系统而是进入ROM模式解决办法:
在ROM模式下使用TFTP协议传输方式重新装系统可以解决(实验过3次都可解决)方式如下:
在电脑架TFTP服务器,打开Tftp32.exe,点击“浏览”选择需要装入的系统IOS,电脑要设置静态IP。

rommon 1 > IP_ADDRESS=192.168.1.115 /设置路由器需要转IOS时使用的IP
rommon 2 > IP_SUBNET_MASK=255.255.255.0 /子网掩码
rommon 3 > DEFAULT_GATEWAY=192.168.1.1 /网关
rommon 4 > TFTP_SERVER=192.168.1.220 /TFTP服务器的IP也就是电脑的IP
rommon 5 > TFTP_FILE=c2800nm-advipservicesk9-mz.124-8a.bin /需要装入的IOS的名称
rommon 6 > tftpdnld /开始传输命令
