Enabling Port Security with Sticky MAC Addresses on a Port

To enable port security with sticky MAC addresses on a port, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# switchport port-security
mac-address sticky
Router(config-if)# no switchport port-security
mac-address sticky
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet

When you enter the switchport port-security mac-address sticky command:
All dynamically learned secure MAC addresses on the port are converted to sticky secure MAC
–
addresses.
Static secure MAC addresses are not converted to sticky MAC addresses.
–
Secure MAC addresses dynamically learned in a voice VLAN are not converted to sticky MAC
–
addresses.
New dynamically learned secure MAC addresses are sticky.
–
When you enter the no switchport port-security mac-address sticky command, all sticky secure
MAC addresses on the port are converted to dynamic secure MAC addresses.
To preserve dynamically learned sticky MAC addresses and configure them on a port following a
bootup or a reload, after the dynamically learned sticky MAC addresses have been learned, you must
enter a write memory or copy running-config startup-config command to save them in the
startup-config file.
