     Table 1 Sticky MAC Enable

     Parameter	Description
     Port Security	Indicates whether to enable port security. The options are Enable and Disable. By default, port security is disabled. The following parameters are available only when Enable is selected.
     Sticky MAC Enable	Indicates whether to enable the Sticky MAC function. The options are Enable and Disable. By default, the sticky MAC function is disabled. NOTE: If the number of sticky MAC addresses on an interface does not reach the limit, the newly learned MAC addresses are converted to static MAC addresses. When the number of sticky MAC addresses reaches the limit, non-sticky MAC entries are deleted when new MAC addresses are learned.
     Interface Protect Mode	Indicates the interface protection mode, that is, the action performed when the number of learned MAC addresses reaches the limit. The options are: Discard The interface discards all the subsequent packets whose source MAC addresses are not in the MAC table. Discard and Alarm The interface discards all the subsequent packets whose source MAC addresses are not in the MAC table and sends a trap. Shutdown The system shuts down the interface and generates an alarm. If the sticky MAC function is disabled, the interface does not send a trap when the number of learned MAC addresses reaches the threshold even if you select the Discard and Alarm option. In this case, the interface only discards new packets whose source MAC addresses are not in the MAC table.
     Max MAC Entries Learned	Indicates the maximum number of MAC addresses that an interface can learn. This parameter limits the number of entries in the MAC table.
