MAC Table
MAC Address Table Configuration
The MAC address table can be configured on this page. Set timeouts for entries in the dynamic MAC
table and configure the static MAC table here.
Figure 131 - MAC Address Table Configuration
1) Aging Configuration
By default, dynamic entries are removed from the MAC after 300 seconds (as shown above). This
removal is called Aging. You can configure Aging Time by entering a value in the box of Aging
Time. The allowed range is 10 to 1000000 seconds. You can also disable the automatic aging of
dynamic entries by checking Disable Automatic Aging .
2) MAC Table Learning
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. You can configure the port to dynamically learn the MAC address
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 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.
