How to check whether the license activation fails because of an ESN mismatch on S series switches


For S series switches (except the S1700), a license fails to be activated or is in Demo state mostly because the ESN of the switch does not match that in the license file. You can locate the fault as follows:
1. Run the display esn command to query the ESN of the switch.
2. Run the more command to check the content of the license file. Query the ESN in the license file.

3. Check whether the two ESNs obtained using the preceding method are the same. Pay attention to tiny differences between the two ESNs, for example, the uppercase and lowercase characters and the difference between the letter O and digit 0. If the ESN in the license file differs from that of the switch, use the ESN of the switch to reapply for a license.
