PROCEDIMIENTO PARA CAMBIAR IOs Y/o firmware
Tanto para cambiar el Firmware como la IOS lo que se hará será borrar todo el contenido de la flash y volver a copiar primero la IOS y después el firmware. Es muy importante que el orden de copia de ficheros sea éste.
Copiamos la IOS a la Flash, cuando nos pregunte si queremos borrar la flash le decimos que sí :
Router#copy tftp: flash:
Address or name of remote host [172.23.9.153]?
Source filename [c837-k9o3sy6-mz.122-13.ZH4.bin]?
Destination filename [c837-k9o3sy6-mz.122-13.ZH4.bin]?
Accessing tftp://172.23.9.153/c837-k9o3sy6-mz.122-13.ZH4.bin...
Erase flash: before copying? [confirm]
Erasing the flash: filesystem will remove all files! Continue? [confirm]
Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee ...erased
Erase of flash: complete

6039348 bytes copied in 93.748 secs (64421 bytes/sec)
Para ver el contenido de la flash:
Router#show flash:
System flash directory:
File Length Name/status
1 6039348 c837-k9o3sy6-mz.122-13.ZH4.bin
[6039412 bytes used, 6281356 available, 12320768 total]
12288K bytes of processor board System flash (Read/Write)
Para que el interfaz ATM de los 83x use el firmware del fichero, tendremos que ponerlo en la flash siempre con el nombre adsl_alc_firmware.bin.
Para que el interfaz ATM de equipos con la WIC-ADSL use el firmware del fichero, tendremos que ponerlo en la flash siempre con el nombre adsl_alc_20150.bin.
Copiamos el firmware a la flash pero en este caso cuando nos pregunte si queremos borrar la flash le diremos que no, ya que ya tenemos copiada la IOS:
Router#copy tftp: flash:
Address or name of remote host [172.23.9.225]?
Source filename [adsl_alc_firmware.bin]?
Destination filename [adsl_alc_firmware.bin]?
Accessing tftp://172.23.9.225/adsl_alc_firmware.bin...
Erase flash: before copying? [confirm]n

La Flash queda de la siguiente manera:
Router#sh flash:

Este comando solo nos da información cuando la línea ADSL ha sincronizado. Para ver el firmware del equipo cuando no hay sincronización ADSL usaremos el comando "debug atm events":
Router#debug atm events
