Hello @Ganesh Devarshetty
It requires a separate license for each member in the stack, and you typically need to register the licenses individually for each switch in the stack.
You need to generate a license token for each switch separately. The license token is unique to each switch's serial number. Register the generated license token for each switch on the Cisco Licensing portal. The registration involves associating the license token with the specific serial number of the switch. After registering the license token, you will receive a license file and apply it to each switch in the stack.
Once the individual licenses are applied to each switch, you can proceed with the StackWise configuration. Assuming the two C9500 has got the same IOS version.
Best regards
