C3850 switch will not save config on reboot

Level 1

Having issues with my C3850 saving config to startup. I've tried a bare basic initial configuration, saved, and reloaded. No dice. I tried the ROMmon mode to check bootvar but it just says it does not recognize the command.

I Get this upon booting.

We do not know enough at this point to give good advice. My best guess at this point is that it might be an issue with the setting of the config register. I would suggest these steps to investigate the issue:

- boot the switch and go through the configuration dialog and create a basic config.

- do the copy run start

- do show start and confirm that the basic config is in startup

- do show version and look down at the bottom and find the config register.

- post that part of the show version output.

If that does not resolve the issue then perhaps you can tell us a bit more about the switch:

- is this switch new to you or have you had it a while?

- if you have had it a while has it worked before and this behavior is a new thing? 

- what version of code is this switch running?

Post the complete output to the command "sh romvar".

It is new to me but it is secondhand.

It seems you need these two commands:

config-register 0x102
no system ignore startupconfig

no good this is the output:

Main#config-register 0x102
Translating "config-register"...domain server (255.255.255.255)
% Unknown command or computer name, or unable to find computer address
Main#no system ignore startupconfig
^
% Invalid input detected at '^' marker.

tried in

configure terminal

and sill no go.

Thank you for the output that I requested. The significant part is this

Configuration register is 0x142 (will be 0x102 at next reload)

The 0x142 instructs the switch to ignore startup config at boot, which explains the problem that you have been having. And the 0x102 is the result of your config change and that at the next boot it should use startup config. 

Boot the switch again and let us know the result.

its the repeat of first post

I am surprised that the problem still occurs. Please post the output of these commands
show run all | include startup

show version

may code updating fix this? possibly: 03.06.06x

I am surprised to see these in the most recent output

My request to reboot the switch was not that long ago.
