Re: PIX 515 boot in loop

Re: PIX 515 boot in loop

If you have followed the password recovery procedure - you will know that you are actually interupting the boot process, BEFORE the device actually loads the config file.

I suggest you read the link I posted and try it.

Re: PIX 515 boot in loop

hello, thanks for you information about the password recovery procedure, but the actual problem is that my device boots with 7.2.3 version of software and starts to proceed my configfile that was imported from V6.3 and the device crashes while proceding the configfile so that i'm not able to type any command line into it in order to erase my flash of config file. so i was wondering how it was possible to clear flash without being logged into the device.

i have already tried the password recovery procedure, because i hoped that it coul'd help me to clear my config file

Best regards

Re: PIX 515 boot in loop

During the bootup, press the esc key during the first 10 seconds. The boot process will look similar to this:

Cisco Secure PIX Firewall BIOS (4.2) #0: Mon Dec 31 08:34:35 PST 2001

Platform PIX-515E

System Flash=E28F128J3 @ 0xfff00000

Use BREAK or ESC to interrupt flash boot.

Use SPACE to begin flash boot immediately.

Flash boot interrupted.

0: i8255X @ PCI(bus:0 dev:14 irq:10)

1: i8255X @ PCI(bus:0 dev:13 irq:11)

2: i8255X @ PCI(bus:1 dev:0 irq:11)

3: i8255X @ PCI(bus:1 dev:1 irq:10)

4: i8255X @ PCI(bus:1 dev:2 irq:9 )

5: i8255X @ PCI(bus:1 dev:3 irq:5 )

Ethernet auto negotiation timed out.

Ethernet port 1 could not be initialized.

Use ? for help.


Now you can follow the password recovery procedure and boot without a config. Once the pix is booted, you can erase your old config by typing: "write erase" or "clear configure all".

Re: PIX 515 boot in loop

hello thanks again for this explication, i managed to clear the password from the pix.

BUT when it'e reboots, il start to load the config file and then crashes so that i can't type any command to clear my config file

Re: PIX 515 boot in loop

Follow the upgrade procedure and load your os via tftp. Once it has loaded, either copy the config OFF of the pix, delete the local copy and reboot, or erase the config using the commands in my previous message.

Please rate if helpful.

Re: PIX 515 boot in loop


PIX has this problem.

1. It can be possible a hardware problem.

2. Software Image not uploaded or damaged.


1. Try to revert back to the old IOS running on the pix.

get the traceback logs from the pix after reload to troubleshoot more.

2. Try to reupload a new image.
