Re: IOS Upgrade Problem

hi there,

permission denied problem is basically from tftp server end type.

Not enough space is because of new IOS size is more as that of available space in flash.

what is the name of the tftp software you are using.

Re: IOS Upgrade Problem

I have tried with solarwind, 3cdaemon and Cisco TFTP server. I am not having any problem when take the backup of current IOS with all above mention TFTP servers, only when uploading the IOS i m getting following errors,

I have already rmeoved the sdm and other files from Flash now only old IOS left, It should give me erase IOS during copy of new IOS but it didnt.

Re: IOS Upgrade Problem

It looks like that your flash doesnot have enough memory to copy the file. Your options are :

1. Delete the existing IOS in the flash and copy the new one.( risk is involved as if router reloads once the IOS is deleted you will be in mess)

2. Boot the router from the network using the TFTP server and once the router is up and running with the new IOS, you can safely remove the old IOS and copy the new one to the flash.

use the following :

config# boot system tftp://172.28.92.72/c2800nm-ipvoice_ivs-mz.124-3g.bin

ctrl+z

write memory

reload

Re: IOS Upgrade Problem

Are you sure that you have the proper permissions to read the file from the TFTP server? Your permissions error may not be related to the Cisco device but to the file on the TFTP server (or location of the file on the server).

Address or name of remote host []? 172.28.92.72

Source filename []? c2800nm-ipvoice_ivs-mz.124-3g ----->why u are not using .bin here and thats why its saying error opening have you added permission denied or you have added it.
