Figure 8-1: The MAC Address Table Configuration
Parameter description:
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.
Static MAC Table Configuration
The static entries in the MAC table are shown in this table. The static MAC table can contain
64 entries. The maximum of 64 entries is for the whole stack, and not per switch.
The MAC table is sorted first by VLAN ID and then by MAC address.
Delete :
Check to delete the entry. It will be deleted during the next save.
VLAN ID :
