Re: IOS Problem after Update > no "copy runn start"

Robert_Berger · ‎07-02-2004

Hello everybody,

After updateing IOS

from: c1700-k9o3sv8y7-mz.123-2.XE.bin

to: c1700-k9o3sv8y7-mz.123-8T.bin

on a Cisco1760-V3PN/K9

i can not save the running config. By console, by telnet ssh, by SDM 1.2

IOS Message:

myxx# copy runn start

Destination filename [startup-config]?

Building configuration...

% Warning: Saving this config to nvram may corrupt any network management or security files stored at the end of nvram.

Continue? [no]:

What to Do ?

I tried with "erase startup..." but it does not help

Now i get massages like:

.Jul 3 10:20:13.771 UTC: %SYS-4-CONFIG_NV_OVERRUN: Non config data present at the end of nvram is corrupted[OK]

thank Robert

Sounds like your config file is larger than the NVRAM. I'm not familar with the 1700 series but I had this issue today on a 3620 with 12.2(5).

near the bottom of a 'show version' will display the size of the NVRAM. In my case the "non-volatile configuration memory" is only 29K. As seen in the show flash output my config file 'router-confg' is over 38K. The way around this was to configure compression for the config file. This may or may not be an option for your 1700.

router#config t

service compress-config

exit

router#sh ver

Thank's!

After searching in Knowlidge Base i found the compress option.

Anyway it was interresting that my config was 13 k and NVRAM was 32 k and shows me 8 k free at the time of message.

"this is now the picture with compression with a 14 k config"
