624 Port and System Security
When link goes down on a port, all of the dynamically locked addresses are
cleared from the source MAC address table the feature maintains. When the
link is restored, that port can once again learn addresses up to the specified
limit.
The port can learn MAC addresses dynamically, and a list of static MAC
addresses can be specified for a port. The number of static addresses that may
be configured is limited by the port security limit, regardless of whether port
security is enabled on the interface or not.
Default 802.1X Values
Table 19-1 lists the default values for the Port Security feature.
