Reset config to factory defaults/Erase config

[LRU]

Hi,
is there any way to reset a OmniSwitch 6850 to factory defaults, i.e. erase all existing configuration?
I do have the current password!
But i would like to come back to a clean onfiguration.
So how to erase all configuration settings?
Thanks.

HI There

You need to console to the switch and reboot it.
WHile booting, you need to interrupt the boot, to get to the CLi prompt

From there you need to enetrer the following commands:

setenv bootflags 0x1000
saveenv
boot

THis takes you to a Mini boot prompt. Once here, just delete the UserTable file under the /flash/network directory.

Once done, reboot the switch again, and interrupt the boot again.

DO the following command then

setenv bootflags 0x0
saveenv

Reboot the switch again, and that should be it....

Hello,
thanks, but that looks like it will reset the user database and passwords.
But i'd like to reset all the configuration to factory defaults too.
Does it do this??

Hi ,

Let the 6850 boot.
Login. Then the secret is to delete both boot.cfg files form the working and certified directory:

cd working
rm boot.cfg
cd ..
cd certified
rm boot.cfg
reload

and here you go, brand new empty configuration. You can validate with

show configuration snapshot

Yes, many thanks!
Some precision concerning the password reset procedure:

[Press a key quickly!]

=> setenv bootflags 0x1000
=> saveenv
=> boot

[booting...]

If you need to also remove the stack topology file remove the boot.slot.cfg file from the root.

[frank]

Yeah.
Once you log in the switch, do that:

rm /flash/working/*.cfg
rm /flash/certified/*.cfg
reload

This will reboot to default

If you want to remove the login / password to , you need to go in the network folder, and delete the user table.
before the upload above , do "cd network" then "dir". You will see a file called usertableX or something like that.
Just do "rm xxxxx" xxxx being the name of the file (case sensitive) then enter the command "reload".
You'll be all set.
