Cisco Cisco IOS Software Release 12.0(1)T Guide De Dépannage

copy from the TFTP server to your Flash.

Note: Before copying, make sure you have started the TFTP server software on your PC and that you
have the filename mentioned in the TFTP server root directory. We recommend that you keep a copy
of the access server configuration before upgrading the access server software. The upgrade itself
does not affect the configuration (which is stored in nonvolatile RAM − NVRAM).

For RCP applications, substitute RCP for every occurrence of TFTP. For example, use the copy rcp
flash command instead of the copy tftp flash command.

If necessary, you can copy an image from one device to another.
Specify the IP address of the TFTP server.

When prompted, enter the IP address of the TFTP server as in this example:

Address or name of remote host []? 172.16.125.3

2. 

Specify the filename of the new Cisco IOS software image.

When prompted, enter the filename of the Cisco IOS software image to be installed, as in this
example:

Source filename []? c5400−is−mz.121−5.T10

3. 

Specify the destination filename.

This is the name the new software image has when it is loaded onto the router. The image can be
named anything, but common practice is to enter the same image filename.

Note: By default, the router uses the source name. If you wish to keep the destination file name the
same as the source file name, just press Enter.

Destination filename [c5400−is−mz.121−5.T10]? 

Note: If you see this error message:

%Error copying tftp://172.16.125.3/c5400−is−mz.121−5.T10  

(Not enough space on device) 

This indicates that there is not enough room available in Flash to copy the image. You need to erase
one or more files from Flash to make room for the new image. The "Erase Files from Flash" section in
Step 5 explains the procedure to accomplish this.

This sample output illustrates the procedures described above:

AS5400# copy tftp: flash:

Address or name of remote host []? 172.16.125.3

Source filename []? c5400−is−mz.121−5.T10

Destination filename [c5400−is−mz.121−5.T10]?

Loading c5400−is−mz.121−5.T8 from 172.16.125.3 

(via FastEthernet0/1): !

4. 

Erase files from Flash:

Make sure you have enough memory before doing the download by using the show flash command.
If you do not have enough memory, you need to erase the file and squeeze Flash afterwards.
