the address does not exist in the table by examining the source address of each packet
received on a port. This is called learning. It allows the MAC table to expand dynamically. If the
learning mode for a given port is grayed out, it means another module is in control of the mode,
and thus the user cannot change the configurations. An example of such a module is
MAC-Based authentication under 802.1X.
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 the link used for managing the switch is added to
the static Mac table before changing to secure learning mode,
otherwise the management link will be lost and can only be
restored by using another non-secure port or by connecting to the
switch via the serial interface.
Static MAC Table Configurations
This tablet shows the static entries in the MAC table which can contain up to 64 entries. Using
static MAC address entries can reduce broadcast packets remarkably and are suitable for
networks where network devices seldom change. You can manage the entries in this page.
The MAC table is sorted first by VLAN ID and then by MAC address.
