3650 switch always reboots to initial configuration dialog prompt

JohnW63
Level 1
Level 1

A 3650 switch I am setting up does not retain the running config and goes to the setup dialog prompt. I have gone into terminal and used the "switch_ignore_startup_cfg=0" command with no effect. I even tried setting the register to the hex value, but I believe that is just for routers. I install a running config and copy it to the start-up config every time. Do I have to go into the ROMMON to use the ignore command properly ?  This isn't the first switch I've had this issue with a switch.

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

Can you change the config register to 0x102, save and reboot?

That worked. 

 

How does ..."no system ignore startupconfig switch all" differ from the command, "switch_ignore_startup_cfg=0" ?

 

John

One you issue on ROMMON Mode, One you using in the config mode.

Hi @balaji.bandi 

Thank you very much, @balaji.bandi! The commands above helped me solve the issue of the 3650 booting into the set dialog prompt. The switch was not saving the configurations.

Thanks

The switch was not saving the configurations.

most case if the switch not saving the configuration, then check the conf register

show version (show you what config reg set) as mentioned above post

or post show version here to guide you.
