Usage guidelines
After you execute this command, you cannot manually configure sticky MAC address, and secure
MAC addresses automatically learned by a port in autoLearn mode are also 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.
You can display dynamic secure MAC addresses by using the
display port-security mac-address
security
command.
Examples
# Enable the dynamic secure MAC function on interface GigabitEthernet 3/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 3/0/1
[Sysname-GigabitEthernet3/0/1] port-security mac-address dynamic
