Does port security dynamically learn mac addresses without sticky

When it comes to securing network ports with unique devices like printers or servers, port security plays a crucial role. One common method used is sticky learning, which associates a specific MAC address with a particular port on the switch. However, what happens when you need to change the device's network card or replace the device altogether? Can port security dynamically learn new MAC addresses without relying on sticky configuration?

The answer lies in understanding how traditional sticky learning works and its limitations. Typically, we use sticky learning for devices that don't frequently change their MAC address, such as printers with a fixed IP address. The problem arises when you need to update the device's network card or replace it entirely.

In these situations, even clearing port-security settings doesn't work, leaving you stuck (pun intended) without an effective solution. So, what can be done? According to Cisco documentation, one possible approach is using dynamic MAC-address association with no sticky option enabled.

Without sticky learning, the switch will dynamically reconfigure and add removed addresses to its address table as dynamic addresses after a specified period of time has passed. This means that when you introduce new devices on your network or replace old ones, port security can automatically learn their MAC addresses without requiring manual configuration changes.

In summary, while traditional sticky learning provides reliable but inflexible solutions for securing specific ports and devices, modern switches offer an alternative approach to dynamically learning MAC addresses through dynamic association. By leveraging this feature, you can ensure seamless integration of new or replaced devices on your network while maintaining optimal port security settings.
