MAC Table Learning
If the learning mode for a given port is grayed out, another module is in control of the mode, so that it cannot be
changed by the user. An example of such a module is the MAC-Based Authentication under 802.1X.
Object Description
•
Auto Learning is done automatically as soon as a frame with unknown SMAC is
received.
•
Disable No learning is done.
• Secure Only static MAC entries are learned, all other frames are dropped.
Note: Make sure that the link used for managing the switch is added to
the Static Mac Table before changing to secure learning mode, otherwise
the management link is lost and can only be restored by using another
non-secure port or by connecting to the switch via the serial interface.
