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
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: 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.
VLAN Learning Configuration
Learning-disabled VLANS:
This field shows the Learning-disabled VLANs. When a NEW MAC arrives
into a learning-disabled VLAN, the MAC won't be learnt. By the default, the
field is empty. More VLANs may be created by using a list syntax where the
individual elements are separated by commas. Ranges are specified with a dash
separating the lower and upper bound. The following example will create
