How to put my ASA 5505 into single router mode so I can restore factory defaults?

  • 772

I'm trying to restore an ASA 5505 to the factory defaults. According to the instructions from several sources (e.g. http://www.mailbeyond.com/restoring-factory-defaults-to-the-cisco-asa5505-firewall-via-the-console) I need to run the following command:

ciscoasa(config)#config factory-default

But this returns:

ERROR: command can only be executed in single router mode

The command to put the ASA into single router mode should be:

ciscoasa(config)#mode single

But this returns:

ciscoasa(config)#mode single
                   ^
ERROR: %Invalid input detected at '^' marker
firewall system-restore cisco-asa reset

    The 5505 is not capable of running in multiple context mode. This is probably just a bug. I would:

    1. backup your config: more system:running-config then save this config to a txt file
    2. wr erase to erase the startup config
    3. reload and say no when it asks you to save the current running configuration
