Re: i cant get cisco 3850 switch from stack mode

AM777RO · ‎10-16-2023

Hello all

I am currently facing a problem when trying to remove the switch from the stack, as I tried all the commands but it still does not switch to standalone mode.

When the switch is restarted, it goes to the elections and config is lost....

is their any solution ??

Is that switch still connected to the stack?

AM777RO · ‎10-16-2023

no, the switch disconnected from the stack a month ago ... and the admin at this time but it in reserve

but now i wont to use it as standalone SW ... i tried switch clear stack-mode

but after reload its back to stack config... again

Leo Laohoo · ‎10-16-2023

To clear out the config, use the following command:

factory-reset config

And then reboot the switch.

i tried this command

factory-reset config

and

factory-reset all

both didn't work

Leo Laohoo · ‎10-17-2023

Please explain with "didn't work"?

The command didn't work? The factory-reset didn't work (because the switch boot into ROMMON)? What?

AM777RO · ‎10-17-2023

after initiating factory-reset all

the switch rebooted and enter into ROMMON mode asked me to provide new IOS.bin .... after fleshing the new IOS the switch boot processes started and it shows me the same

also this happens with factory-reset config command

The switch is stack-capable. I do not see anything wrong with the logs.

show boot and show us stack settings

if 2 switch stack cables are disconnected, switch should load default config; check flash for config.txt or .cfg file; if there is one, boot to switch mode (aka ROMMON mode) by holding Mode button at reboot for 20 sec. Initialize flash and check settings of your switch; Use ? to figure out commands; finally u could delete your config file forcing switch to load default settings;
