Primeiro abre o servidor TFTP em uma estao, depois usa o comandocopyoque?tftp(onde oque? Pode ser aflash, NVRAM, RAM, etc...) informe o ip (223.8.151.3)deste servidor e o nome do Arquivo de BACKUP (leandro_router).

Lab_C#copy star tftp

Address or name of remote host []?223.8.151.3

Lab_C#

Para copiar do servidor TFTP use o comandocopy tftprun ,onde run pode ser substitudo por qualquer tipo de memria do roteador.
