On C4900 i am not able to change the config-register value to 0x2102. In the config mode i gave the command "config-register to 0x2102" and did a write memory. After which when i do a "show ver", it does not reflect that the config-register value will change at next reload. Ideally this line should be seen at the end of Show ver output. "Configuration register is 0x3122 (will be 0x2102 at next reload)"
Is there something that i am missing to do?
