Reset Cisco PIX 506E to factory defaults

taonrez — Sat, 21 Jan 2023 10:38:42 GMT

Hello Cisco Team,

I am using a cisco pix 506e firewall.
I would like to reset the default settings of this firewall.

But I forgot the administrator password and the IP addresses of the different interfaces.

Thank you in advance.

Hi balaji.bandi,

In the password reset procedure you mentioned,
In step 9, the monitor>address “Cisco IP Address” command, I would like to know if “Cisco IP Address” represents the IP address of interface 0 (Ethernet 0) that already exists or is it the IP address that I need to define?

If “Cisco IP Address” represents the IP address of interface 0 (Ethernet 0) that already exists , I no longer know its IP address. My question is also how to find this address.

Thank you in advance for your response.
