Is there a way to limit the number of MAC addresses that a particular port can learn? I’m aware of the switchport port-security maximum command, but I’m just wondering if I can simply limit the number of MACs on a port without configuring the switchport port-security command in either a dynamic, static, or sticky method? In other words, I don’t care what MAC address the port learns, but I only want it to allow 1, 2, or whatever number MAC addresses I choose. For example, I just want it to learn 3 mac addresses and every MAC after 3 gets ignored. I hope my question makes sense. Thank you.
