There are three types of secure addresses that port security uses:

  • Static - This are addresses that you specifically configure using switchport port-security mac-address xxxx.xxxx.xxxx.
  • Dynamic - This are addresses that the switch learns though the usual process of MAC address learning. These will eventually age out, allowing different MACs to be learned/permitted.
  • Sticky - These are a compromise between static and dynamic. Sticky addresses are learned dynamically, and then added as (functionally) static addresses in the running-config. This means you can learn the address dynamically but not have it time out with MAC table aging. Sticky learning is configured with the switchport port-security mac-address sticky command.

Perfect explanation. Thanks!
