ASA NVRAM size

[Kfir Mesika]

Hey all,

How can I know the NVRAM size of an ASA 5510? (or any other ASA)

Is there a official doc regarding this?

Already tried:

show file system

show ver

show tech info

dir...

nothing!

Your help please

"show flash" will show you the size of NVRAM on ASA.

Hey Jennifer

The "show flash" shows the flash and RAM

I need to see the NVRAM

Is there a technical doc describing it?

Hi,

NVRAM = Non Volatile Random-Access Memory = Flash

Its where the Start-up configuration is stored. (Among other things)

Just use "dir flash:" or "show ver" and look how much you have

Example from one of our devices:

Internal ATA Compact Flash, 2048MB

It sounds strange to me that Flash and NVRAM are the same

Is there an official doc about it?

besides our configuration is small (80K) and we saved about 30 Crypto keys (of 2048K each) and we got an error that our NVRAM is full

Increasing the flash didn't help

Yup, that is a known error as there is a limit to the total size of keypairs that can be stored on NVRAM (it doesn't depend on the amount of flash storage that you have as it has a maximum limit within flash for keypair storage).

Once you received the error message:

WARNING: NV RAM will not have enough space to save keypair keyXX. Remove any unnecessary keypairs and save the running config before using this keypair.

Then you know that you have hit that limit within NVRAM.

Hey Jennifer

Thanks alot

Is there an official doc about this error? I didn't found it

Don't believe there is an official document on this unfortunately.

This is the output of the show file system where you can see the nvram split from flash:

File Systems:

how does the system handle the nvram if it is the same flash?
