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.
To disable the automatic aging of dynamic entries, check Disable automatic aging.
MAC Table Learning
If the learning mode for a given port is grayed out, another module is in control of the mode,
so the user cannot change it. 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, not per switch.
The MAC table is sorted first by VLAN ID and then by MAC address.
Delete :

VLAN ID :

MAC Address :

Port Members :
Checkmarks indicate which ports are members of the entry. Check or uncheck as needed
to modify the entry.
Adding a New Static Entry :

port members for the new entry. Click "Save".
