I am using Cisco 9300 48UXM-E, after configuring when I reload the switch I am losing configuration. Switch is coming as new and when we use command copy start run config is coming back. On my research I understood that config-register is not changing from 0x2142 to 0x2102 after reloading. Can anyone please help me to overcome this issue.

Did you check the configuration for the offending line I've pointed out?

Hi @Pavan.0703,
Two tests:
-Try with the command: S#copy running-config startup-config
-Check the current register of your device

Would the original poster please post the output of show version. We would like to verify the value of the config register.

Several of us seem to be operating from the assumption that the issue is the value of the config register. There have been several requests to verify what is the value of the config register but so far no information about the content of the config register. Leo has identified another very interesting possibility about the issue. But so far no response to his suggestion either.
The most recent post from the original poster seems to suggest that he believes that doing copy run start should change the value of the config register. I do not have experience with the 9300 switches. But on every Cisco switch with which I do have experience doing copy run start has no effect of changing the config register. You change the value of the config register with a configuration command in global config mode or you change the value in rommon.

Check the config if this command is present: system ignore startupconfig switch all

Entering the following commands worked for me:
switch (config)# no system ignore startupconfig switch all
switch (config)# switch all config-register 0x102
Copy run start
Reload

does not work on a 9300 running 17.3.5 for me
