These parameters are displayed:
Aging Configuration
◆ Disable Automatic Aging - Disables the automatic aging of dynamic
entries. (Address aging is enabled by default.)
◆ Aging Time - The time after which a learned entry is discarded.
(Range: 10-1000000 seconds; Default: 300 seconds)
MAC Table Learning
◆ Auto - Learning is done automatically as soon as a frame with an
unknown source MAC address is received. (This is the default.)
◆ Disable - No addresses are learned and stored in the MAC address
table.
◆ Secure - Only static MAC address entries are used, all other frames are
dropped.
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 will be lost, and can only be restored by using
another non-secure port or by connecting to the switch via the serial
interface.
N OTE :
If the learning mode for a given port in the MAC Learning Table is
grayed out, another software 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.
Static MAC Table Configuration
◆ VLAN ID - VLAN Identifier. (Range: 1-4095)
◆ MAC Address - Physical address of a device mapped to a port.
A static address can be assigned to a specific port on this switch. Static
addresses are bound to the assigned port and will not be moved. When
a static address is seen on another port, the address will be ignored
and will not be written to the address table.
◆ Port Members - Port identifier.
