Usage guidelines
If only the aging timer is configured, the aging timer counts up regardless of whether traffic data has
been sent from the sticky MAC addresses. When you use the aging timer together with the inactivity
aging feature, the aging timer restarts once traffic data is detected from the sticky MAC addresses.
The inactivity aging feature prevents the unauthorized use of a secure MAC address when the
authorized user is offline. The feature also removes outdated secure MAC addresses so that new
secure MAC addresses can be learned or configured.
This command takes effect only on sticky MAC addresses and dynamic secure MAC addresses.
Examples
# Enable inactivity aging for secure MAC addresses on GigabitEthernet 1/0/1.

Usage guidelines
The dynamic secure MAC feature converts sticky MAC addresses to dynamic and disables saving
them to the configuration file.
After you execute this command, you cannot manually configure sticky MAC addresses, and secure
MAC addresses learned by a port in autoLearn mode are dynamic. All dynamic MAC addresses are
lost at reboot. Use this command when you want to clear all sticky MAC addresses after a device
reboot.
