3.1.11 MAC TABLE
The MAC Address Table is configured on this page. Set timeouts for entries in the dynamic MAC Table and configure the
static MAC table here.
Aging Configuration
By default, dynamic entries are removed from the MAC table after 300 seconds. This removal is also called aging.
Configure aging time by entering a value here in seconds; for example,
Age time
seconds.
The allowed range is
10
to
1000000
seconds.
Disable the automatic aging of dynamic entries by checking
Disable automatic aging
.
MAC Table Learning
If the learning mode for a given port is greyed 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.
Each port can do learning based upon the following settings:
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.
