Asa 5505 Factory Reset

[Katrine Freggiaro]

Wejust took on a new client and they do not have the username or password for their ASA 5505. Unless anyone has any ideas, we need to reset to factory defaults. I have read some instructions online how to do this, but they require the password. How do we do it without the password?

Basicly to my understanding it interrupts the normal ASA boot and lets the ASA boot without configuration. When the ASA has booted you will load the configuration to the ASA (as you have already accessed its CLI) and you change the AAA information to what you like and save the configuration.

Dont know if its just me or should the Step 13 be the other way around. Copy startup to running? Wouldnt we otherwise be copying a blank configuration to the startup and therefore loose the old configuration completely? I guess I must have just understood it wrong myself.

i have a question. after reset password with this method, which configuration have asa5505? it's factory configuration or configuration before reset password? i forgot password i don't want to loose my configuration, i don't have backup.can i apply this method for reset password i my case?

A factory reset (configure factory-default) from the console will reset just the config and not erase the added license keys, correct? I don't have access to the original keys (they were installed by the previous owner) and don't want to lose access to these extra features.

I can confirm that the Cisco ASA 5505 indeed does not lose the activation key/license when performing the factory reset. No action is required after the factory reset - it boots back up with the key intact.

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

I always like to make sure the running configuration is saved to non-volatile flash memory in case the ASA 5505 loses power. The way to ensure the unit will come back up correctly in the event of a power failure is to reboot it!

show version and then look for licence. Mine says base license, you can also look at vpn users and such as that is the part you are upgrading for primarily.10 total vpn users on base license. 50 for upgraded, or unlimited for premium package.

i did the same procedure on cisco asa 5510 series but when i reloaded after a reboot no configuration was found in running configuration even i copied startup-config to running-config but still when i reboot it the running-config is somehow erased or removed

could you please tell me about this

hello, my apologies, im a newbie too and as most of the people around here, out network admin is no longer with the company and left me nothing. i have an asa 5505 and recently we changed the company IP and i needed to set that up in the router but i couldnt login. so i decided to do a factory restore and start from a clean slate. i was able to do it and it was giving me an ip but i needed to remove the password and i reset it again to factory and now i am not getting any ip address at all. its giving me a 169.254.60.195 ip address. need your expertise.

thanks for the quick response, i did try to reset it again for about 3 or 4 times now and being careful to follow the instructions carefully. on my initial reset it did work and i was getting an ip address 192. but i couldnt log in to asdm so i reset the password and did another factory reset again but now im only getting a 169 ip and port zero is plugged in to our network but when i plug in my pc to port 1-5, i do not get any led lights only on 6 and 7 but still not giving me any address. i cant connect using asdm nor and i have tried resetting it numerous times and nothing.

my cable is straight through and i can connect to the network directly. and we are running dhcp. our ip is at 10.0.0.x range. i have tried unplugging the uplink and just use one cable to connect the device, there are no link lights form 0-5 only 6-7 and it will still give me 169 ip. i tried pushing the reset button at the back but it seems useless. i can still connect to the device using the console but no asdm or https. any ideas? thanks

Have your lawyer write them a letter threatening legal action if they do not hand over the passwords. Make sure to be clear that if recalcitrant IT company causes any interruptions in productivity that they will be sued for those damages.

I have tried to reset the ASA 5505 that i have, i have followed all the advice, but i am getting no where, the device i have was set up quite some time ago and left, the guy has left the ocmpany with the settings for the device.

When i try a hyperterminal session with the device, i get nothing, i cant even get the device Command line when i press enter a few times, i know the session is there as when i power off and on again, i get the:

cisco systems page that tells me the BIOS version, and at the bottom the ROMMON version, but i cant get an further on with the reset to factory default?????

Any help anyone.

Thanks for your very helpful information. I have one question. I would like to reset using the factory-default but I need to set the Management IP address to one on my existing network. At the same time since it will be plugged into an existing network with a working DHCP, I need to disable the dhcp and just give the management interface a static IP that I can hit over the network. Is that possible or should I just try to set it up using the ASDM and my laptop?

PS I am about to change over from an existing Windows Server 2003 ISA 2006 firewall to my new Cisco ASA 5510 firewall. Any suggestions or hints for making it as painless as possible. Thanks so much for your help.

Sonicwall are so much easier to use and have a faster throughput when compared to similar Cisco device and much cheaper, i though when i finally got into the ASDM and configured the ASA i was thinking these cisco devices are so bad after all but for a device to not save its own config, whats that about?

I have followed the instructions to reset to factory settings. Completed and believe everything worked. But my computer does not get any ip adderss to conect to. So, I redid the reset many times and get the same result. I have noticed that there is a Error in the executing command lines. It says:

Failed to apply IP address to interface Vlan2, as the network overlaps with interface Vlan1. Two interfaces cannot be in the same subnet.

I have a Cisco ASA 5505 appliance. I have reset it to the factory default settings via CLI. I am able to launch the ASDM. But the ASDM is prompting me for the username and password. There is no default username and password for the ASDM as far as I know, if the ASA has a default configuration.But still the ASDM is not allowing me to access the ASA.I have tried some default credentials like cisco, root, admin etc. but nothing worked. The http server is enabled on ASA.

Log into the CLI using the standard Cisco default user/password and then setup a user account make sure you setup an enable password and also check the https server. If this isnt set its most likey the cause.

I think the problem was that I didn't have any enable password set. Although I had reset the device many times to factory default but still I was not able to login into the device due incorrect login credentials. OR it could be that I have to set an enable password to use the ASDM. So I just configured a new enable password on the ASA and then I was able to login via ASDM with the specified password.

I have no experience backing up and restoring my P7; other threads discuss the best way(s) of doing this. But the answer to the first paragraph is most probably yes. E.G. You could keep the backup on a flash drive (which you presume they will seize and copy) or you could perhaps keep a backup online at home somewhere and download it after entering China.

Were I traveling to China I'd back up my Pixel at home and install a new copy of GOS (thereby scratching any possibly objectionable material) with only apps necessary to have a good visit (there would be many).

When there, be totally up front and honest; no swapping OS's; consider the possibility that your phone will be examined upon entering; while in country; and possibly even during exit.

Upon returning home, copy out photos, recordings, addresses of new friends, etc. and then install GOS and your backup (presuming the phone may have been compromised). Of course you're running verifications.

Regardless, I don't think Google Play services or carrier software could effect this, since factory resets are done either in recovery or after a restart (which would most likely disable most of these applications)

Even then, the weaver would be lost, memory would be cleared, so what would they really be able to do? The data by all accounts is gone as soon as that weaver is dropped (and memory is flushed) and that's done on a firmware level

N3rdTek Pressing the "factory reset" button does not require a second device. But, as missing-root wrote, trusting what happens when you press the button involves trusting some software on the device.

Check in Event Viewer for any Critical, Error or warning events that may be logged at the same time that the laptop crashes. To get to Event Viewer in Win 10, press the Win Key + x key (both together) and then click on the link.

Yeah, both fans work perfectly, I have no overheating problems, when I check the Event Viewer it shows some Error Code 28 and some other related errors, also, when I checked the Device Manager, I found something about Logitech but every time I uninstall it and reupdate the device, the same problems come back. I even reset the computer for factory reset and still have the same problem.

Also did you check event viewer? You seem to be talking about error codes in device manager. With event viewer problems are listed under the categories Critical, error and warning and then show source and event ID number for the event
