On the Port Security Static and Sticky MAC Address page, you can add and
delete static and sticky MAC addresses managed by Port Security, the available options
are shown in the following figure. Port security defines three types of MAC addresses,
of which static and sticky can be added and removed on this page.
Dynamic: A MAC address learned through learn frames coming to the Port Security module while the interface in question is not in sticky mode. Dynamic entries disappear if it ages out or if the interface link goes down.
Static: A MAC address added by end-user
through management. Static MAC addresses are not subject to aging and is added to
the MAC address table once Port Security gets enabled on the interface. Static
entries are part of the running-config and survive interface link
state changes. They reboot if saved to startup-config. Static
entries can be added to the running-config at any time irrespective
of Port Security being enabled.
Sticky: When the interface is in the
Sticky mode, then all entries that otherwise are learned as dynamic, are learned as
sticky. Like static entries, sticky entries are part of the
running-config and survive interface link state changes. They
reboot if saved to the startup-config. Though it is not the
intention with Sticky entries, they can be added by management to the
running-config at any time irrespective of Port Security
being enabled on the interface, if the interface is in the Sticky mode. Sticky
entries disappear if the interface is taken out of the Sticky mode.Figure 4-38. Port Security Static and

Port: The port number to which this MAC
address is bound
VLAN ID and MAC Address: The VLAN ID and
