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.

We had the same with a C3650-48-L-S.
After hard reset and getting it to ROMMON and typing in boot, SOMETIMES this works, most the time not.
Only an RMA solve this issue in our case!

anyone managed to do this on a 2951 ?
02-07-2019 06:29 AM
Hello,
what exactly is the problem with the 2951 ?
06-28-2019 07:29 PM
I wouldn't recommend to disable password recovery
Basically if you lose the password that switch will become a nice paper weight
no system ignore startupconfig switch all
config-register 0x102
Those 2 commands are enough
