MAC Table Learning
If the learning mode for a given port is grayed out, another module is in control of the mode, so
that the user cannot change it. An example of such a module is the MAC-Based Authentication
under 802.1X.
Each port can perform learning based upon the following settings:
Label
Description
Auto
Learning is performed automatically as soon as a frame with unknown SMAC is received.
Disable
No learning is performed.
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.
