Pix Nvram

is there a command to show the free memory of a Pix (where store the pix configuration)?



Re: Pix Nvram


you can have a look at the files in the flash by using the 'show flash' command.

It tells you how many files are stored in flash and the length of the file.

By using the 'show version' command you can see the total size of the flash.


pixfirewall(config)# sh flash

flash file system: version:2 magic:0x12345679

file 0: origin:0 length:1540152

file 1: origin:1572864 length:1387

file 2: origin: 0 length:0

file 3: origin: 2752512 length:4748324

file 4: origin: 7864320 length:280


pixfirewall(config)# sh ver

Re: Pix Nvram

Just to add to this, the PIX flash is partitioned into various sectors, with each partition holding a specific software as follows:

PIX FLASH Partitions

file 0: PIX Firewall binary image, where the .bin file is stored.

file 1: PIX Firewall configuration data that you can view with the show config command.

file 2: PIX Firewall datafile that stores IPSec key and certificate information.

file 3: PIX Firewall PDM image.

file 4: flashfs downgrade information for the show flashfs command.
