Which switching feature removes unused MAC addresses from the MAC address table to make room for new entries?

MAC address aging is the process where a switch automatically removes MAC address entries from its MAC address table after a period of inactivity. This ensures the table doesn't become full of stale entries, making room for new, active MAC addresses and improving switching efficiency. MAC move is when a MAC address is learned on a different port, indicating a device has moved. MAC address auto purge is not a standard Cisco term for this function. Dynamic MAC address learning is the process by which the switch initially populates its MAC address table by observing source MAC addresses on incoming frames, but it doesn't describe the removal of old entries.
