I managed to bork one of our test switches today. I was in the process of enabling “netlogin” using RADIUS as the authentication method, when I must have inadvertently enabled RADIUS authentication for the management interface instead of just for “netlogin”.
Using the Extreme documentation as a clue to resolve this kind of issue, but for a forgotten admin password, I was able to modify the instructions slightly to achieve a logon without resorting to a factory reset.
Follow the initial steps of rebooting the switch with a default configuration. But modify the line you enter into the
autoexec.xsf to suit your config requirements. In my case I needed to
Initial Steps: Reboot the switch with a default configuration
1) Connect to the switch via console connection.
2) Power cycle the switch.
3) During the boot process “hold the spacebar” to enter bootrom.

4) In the bootrom, type the commands below to select a default configuration to be booted:
- If your bootrom version is 18.104.22.168 the option config none is not available, upgrade the bootrom to overcome this.
BootRom > config none BootRom > boot
The switch should now boot with a factory default configuration. Username:admin, Password:[none]
At this point, perform the steps below, to create an autoexec script
Method 1: Creating an autoexec script
1) Enter the vi editor to create an autoexec.xsf file
2) Press the i key to enter insert mode.
3) This is where we enter the command that we want to run after the
primary.cfg config has loaded.
4) Exit insert mode by pressing ESC, then write the file and quit vi by typing
5) Reboot the switch by typing
reboot, but do NOT save the config. Saving the config at this point will overwrite the existing configuration with a blank one.
6) When the switch reboots, the
autoexec.xsf script will be executed, creating the new account.
7) Log in using the admin account should now be possible.
8) Tidy up by deleting the
9) At this point, the switch should be back to its previous configuration. So now make sure you can logon, save the config and you can continue like this never happened.
