When you enable sticky MAC-address learning (
sticky
), dynamically-learned MAC addresses of
trusted devices are added to the running configuration and “stick” to the port or VLAN on which they
are learned even if an interface goes down and comes back up. If you save sticky MAC addresses to the
start-up configuration file by entering the
write config
command, the addresses are deleted from the
running-configuration, do not have to be dynamically relearned, and do not change when the switch
reboots. Any sticky MAC addresses learned after the
write config
is performed are not saved after a
reboot.
