Cisco 1760 Nvram Issue

Hi, I have a router Cisco 1760 working fine but recently I can't save the running-config to start-config. I have used the command service compress-config but I think it doesn't work. Here some additional info:

Router1760#sh user

Re: Cisco 1760 Nvram Issue

When there is simultaneous access to a router's NVRAM, you might encounter these two errors:

While you display the contents of the NVRAM with the show startup-config command:

Router#show startup-config

Using 5524 out of 129016 bytes

%Error opening nvram:/startup-config (Device or resource busy)

While you save a configuration to the NVRAM with the copy running-config startup-config command:

Router#copy running-config startup-config

Destination filename [startup-config]?

startup-config file open failed (Device or resource busy)

Re: Cisco 1760 Nvram Issue

Hi and thanks for your response.

I was checking the users connected to the router, and I am the only one accessing the router. The Nvram shows a new message, but I still haven't found anything in what could be the problem. Any idea??

Regards,

Alexander.

Re: Cisco 1760 Nvram Issue

Hi

Can you try to exectue test memory command ?

it will try to test your nvram and give you the results.

if you get the result as failed take necessary backup and do a write erase.

Re: Cisco 1760 Nvram Issue

Here's what you can try in addition to service compress-config.

router#wr erase

router#wr mem

I have tried this multiple times and it fixed the issue most of the times.

OR

Try the following (Im not sure if the boot config command would work on your platform). This would save your configuration to the flash instead of NVRAM.

Router# wr erase

Router (config)# boot config flash:router-config

Router (config)# end

Router# wr mem

Let us know how it goes.

Re: Cisco 1760 Nvram Issue

Hi,

I did what you recommend, the first one and it works!! In reference to the second part the plataform does not support this command.

Thanks a lot friend!!

Regards, Alexander.

Here is a the results:

Router1760#dir nvram:

Directory of nvram:/

12 -rw- 16048 startup-config

13 ---- 1965 private-config

1 -rw- 0 ifIndex-table

2 ---- 13 persistent-data

29688 bytes total (9575 bytes free)

Router1760#write memory

startup-config file open failed (Not enough space)

Router1760#write erase

Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]

[OK]

Erase of nvram: complete

Router1760#dir nvram:

Directory of nvram:/

27 -rw- 0 startup-config

28 ---- 0 private-config

1 -rw- 0 ifIndex-table

2 ---- 13 persistent-data

Router1760#

Router1760#write memory

Compressed configuration from 15445 bytes to 5729 bytes[OK]

Router1760#dir nvram:
