I have PIX 515E with Cisco PIX Security Appliance Software Version 7.2(2)22.
It had been already configured, so I wanted to set factory setting so i have given following commands..
# write erase
After rebooting I did not get prompt, PIX hangs with following message...
Configuration has non-ASCII characters and will be ignored.
Cryptochecksum (changed): d41d8cd9 8f00b204 e9800998 ecf8427e
Please help me how do get prompt?
Moreover if you want to configure the pIX 515E to factory default the command for it is:
For the PIX 515/515E and the ASA 5510 and higher security appliances, the factory default configuration automatically configures an interface for management so you can connect to it using ASDM, with which you can then complete your configuration. For the ASA 5505 adaptive security appliance, the factory default configuration automatically configures interfaces and NAT so that the security appliance is ready to use in your network.
This command is available only for routed firewall mode; transparent mode does not support IP addresses for interfaces, and setting the interface IP address is one of the actions this command takes. This command is also only available in single context mode; a security appliance with a cleared configuration does not have any defined contexts to automatically configure using this command.
This command clears the current running configuration and then configures several commands.
If you set the IP address in the configure factory-default command, then the http command uses the subnet you specify. Similarly, the dhcpd address command range consists of addresses within the subnet that you specify.
After you restore the factory default configuration, save it to internal Flash memory using the write memory command. The write memory command saves the running configuration to the default location for the startup configuration, even if you previously configured the boot config command to set a different location; when the configuration was cleared, this path was also cleared.
