When applying for a license, you must provide the following information:

• Authorization ID (LAC), Activation ID, or contact No.

  You can obtain the information from the license authorization certificate.

• Equipment serial number (ESN). To apply for a license for a stack system, you need to provide ESNs of all member devices.

  The method of obtaining an ESN varies according to the software version:

  • Versions earlier than V100R005C00

    For CE12800 series switches, run the display esn command.
