I have had a problem recently where when trying to copy images larger than 16Mb via TFTP to various 3600 routers, the transfer fails.
The pair I am currently working on are running 12.2(11)T2. I need to get 12.2.15T onto each router, but when I try a "copy tftp flash", after the first 16Mb, the router console output switches from exclamation marks to zeros and dots:
and then I get the transfer failed message. I have tried Cisco, 3C and Solarwinds TFTP servers all to the same effect.
I would be grateful for any advice anyone could provide on this.
Thank you in advance,
The current image is 14Mb, the new one is 18Mb.
The flash is set to a single 32Mb partition, I believe the chip configuration is 2x16Mb.
Thank you very much for your help.
o's are out of order packets , and dots are timeouts .
did you try to copy a different image ? maybe your image is corrupt .
partition your flash ' partition flash 2 16 16'
then copy the image from partition 1 to partition 2
copy flash1:imagename.bin flash2:iamgename.bin
This will test the second SIMM in flash to make sure it is not bad .
I will not be able to try this until next week now, thank you for your help and I will let you know the result of that test.
Enjor your weekend, Luke.
I had this exact same problem before with a 3640 series. Even though I've had plenty of room for them.
The transfer failed with Cisco TFTP server so I turned on enable logging and it showed a timeout error.
I resolved it by using hyperterminal and using transfer to send it with Xmodem.
Let me know if you try this, because I've had a lot of trouble sending files to 3640's and I could probably recommend something else.
