Re: firewall image

Hi .. both are kept on flash. file 0 is the image and 1 is the config

The show flashfs command displays the size in bytes of each filesystem sector and the current state of

the filesystem. The data in each sector is as follows:

? 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?flashfs downgrade information for the show flashfs command.

? file 4?The compressed PIX Firewall image size in Flash memory.

i hope it hells .. please rate if it does !!!

Re: firewall image

Hi,

Cisco firewall keep the operating system image and firewall configuration (startup-config) in the flash (nonvolatile) memory file system.

When a firewall boots, it uncompresses and copies an executable image from Flash to RAM. The image is actually run from RAM. At this time, the startup configuration commands are copied to the "running" configuration file in RAM (volatile) memory. Any command that is entered or copied into the running configuration is also executed at that time.

Rgds,

AK
