Config Register Not changing after reload

Kanes Ramasamy

Hi Al,

I am having an issue with a Cisco 3850 Catalyst switch, issue as below:

- Current config register is 0x142 and have configured the config register to 0x102 but even after reload the new config register does not come in place.

- Have reloaded the switch 2x but with no luck. Changed the config register on the primary and secondary switch yet no luck. It is running SSO.

Thank you! I've been banging my head on the wall for the last 45 minutes trying to figure this one out (; "no system ignore startupconfig  switch all" and "switch all config-register 0x102" is what fixed it for me.

Cheers!

The output indicates it will change on the next reload (at least switch 02).

Give it a try.

I have a 3850 switch with an identical issue.  I have been unable to get the device to boot using the existing config .

I have the following output in 'sh ver'

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

BUT the device does not reload with 0x102, at the next reload, but continues to exhibit identical behaviour after repeated reboots.

Kind regards

no system ignore startupconfig switch all

config-register 0x102

had the same problem on a brand new C9300-48UXM running 16.9.3. after adding the "no system ignore startupconfig switch all " and "config-reg 0x102" it corrected the problem. Thanks all

thanks
