Which part of StefanosM 's explanation did you not understand?

The licensing guide that quebek posted explains individual agents on page 11.

Please speak to your reseller about the current Veritas T2C (Traditional to Capacity) campaign.
If all of your agent-based licenses are converted to Capacity, you will have a single license key that covers everything you need.
