Cannot write to memory!!

[jolo07310]

We have 2503 router. Let say I type some command, and "write". It seems to write, but if I relaod the router, all command are gone.

I change memory, but problem still exist.

16 Memory/16 Flash with c2500-jk8os-l.122-1d.bin

Anyone knows??

Thanks

Can you paste a show version ? If the config register setting is 0x2142, you will have the config stored in NVRAM, but the router will ignore it every single time. You will need to change that value to 0x2102 by using command "config-register 0x2102" under global configuration mode.

Thanks for your reply.

If I type "show start-config", the commands will be there. Is that true config register setting is 0x2142??

Thanks

The problem should be the config register. Type the following in config mode

config-register 0x2102

and reboot.

NVRAM is typically battery back SRAM, so it may be that the battery is drained. I'm still looking, but it may be that the battery looses charge if the router is not powered up. Has this router been in store?

Also have you confirmed that the configuration actually gets saved? If you do a "sh conf" or "sh start" after the "write", but before the reload, does this show the configuration you expect.

Thanks guys.

Once I change to config-register 0x2102, everything is working now.

Thanks again
