MAC Table Learning
If the learning mode for a given port is grayed out, another module is in control of the mode and
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 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.
