Configuring Port Security on Access Ports
Note
To clear dynamically learned port security MAC addresses in the CAM table, use the clear port-security
dynamic command. The address keyword enables you to clear a secure MAC addresses. The interface
keyword enables you to clear all secure addresses on any interface (including any port channel interface).
The VLAN keyword allows you to clear port security MACs on a per-VLAN per-port basis.

When you specify the
vlan
keyword, the mac-address
becomes sticky in the specified VLAN.
To delete a sticky secure MAC addresses from the address
table, use the
no
switchport port-security mac-address
mac_address
sticky
command. To convert sticky to dynamic addresses,
use the
no
switchport port-security mac-address sticky
command.
Note
This command only applies to access, PVLAN
host, and PVLAN promiscuous mode. For more
