Titolo: Agg. Flash Cisco 827

Salve a tutto il newsgroup. Ho la necessità di ricaricare la flash di un
router Cisco 827.
Ho il file "c820-y6-mz.121-5.YB4", ma non so cosa devo fare per caricarlo
sul router.
Mi sapreste indicare dove trovare una guida per fare il tutto?
Grazie.

Non so se funzia con l'827..... e funziona solo dalla console.
bisogna usare il comando xmodem
rommon 1 > xmodem [?cyrx] <destination filename>
Option Function
 ?c Performs the download using CRC?16 error checking to
 validate packets. Default is 8?bit CRC.
 ?y ymodem?batch protocol uses CRC?16 error checking.
 ?r Loads software image into dynamic RAM (DRAM) for
 execution. Default is to load into Flash memory.
 Note: This option is not recommended because there is no
 file in Flash, and, if the router is reloaded, you have to go
 through the recovery procedure again.
 ?x Loads the software image into DRAM without being
 executed. The image can then be launched with the ROM
 monitor launch command.
 Note: This option is not recommended: see ?r).
 ?f
 Performs a full erase of Flash memory.
 This option is 1600?specific; default on other platforms.
Examples:
rommon 1 > xmodem ?cf c1600?nsy?mz_112?15a_P
rommon 1 > xmodem ?y c2500?js?mz_120?14
Note: The "rommon xmodem/ymodem" transfer only works on the console port.
You can only download files
to the router. You cannot use "xmodem/ymodem" to get files from the router.
Procedure
1.
At the ROMmon prompt, type the following command:
rommon 1 > xmodem c1600?nsy?mz_112?15a_P
Do not send the program yet.
Wait for ROMmon to prompt you to send the image file via hyper terminal
2.
Ready to receive file c1600?nsy?mz_112?15a_P ...
Select Transfer from the menu bar on your hyper terminal program and choose
the Send File option
from the pull?down menu:
3.
Next, select Xmodem (or Ymodem if you used the ?y option) for the protocol
field:When the file has finished downloading, ROMmon issues the following
message:
Download Complete!
4.
To verify the image in Flash, enter the dir flash: command at the ROMmon
prompt. An example is
shown below:
rommon 1 > dir flash:
File size Checksum File name
2179331 bytes (0x214103) 0x7b95
c1600?nsy?mz_112?15a_p
5.
Enter the reset or the bootflash:[filename] command at the ROMmon prompt for
the system to boot
the new software image, as shown below:
6.
rommon 1 > reset
or
rommon 1 > boot flash:c1600?nsy?mz_112?15a_P

Ho provato con il "metodo" di Romadd64 ed ha funzionato. Tempo per l'upload
circa 1,5 ora.
A breve mi devono arrivare tre Cisco 2600 e provero il post di Vimas2001.
Per il momento GRAZIE.
P.S. Avrei un altra domandina ma posto un altro topic :-)

Anche io ho lo stesso problema, dove hai trovato il file per l'aggiornamento
?
Grazie tante STefano
