Aging Time 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:
Items Description
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 MAC table is sorted first by VLAN ID and then by MAC address.
Items Description
Delete Check to delete the entry. It will be deleted during the next save.
VLAN ID The VLAN ID of the entry.
MAC Address The MAC address of the entry.
Port
Members Checkmarks indicate which ports are members of the entry. Check or
uncheck as needed to modify the entry.
Button
Click Add New Static Entry to add a new entry to the static MAC
table. Specify the VLAN ID, MAC address, and port members for the new entry. Click
"Save".
Click to save changes.
Click to undo any changes made locally and revert to previously saved values.
4.3.23 VLAN Translation
Q-in-Q tunneling and VLAN translation allow service providers to create a Layer 2
Ethernet connection between two customer sites. Providers can segregate different
customers’ VLAN traffic on a link (for example, if the customers use overlapping VLAN
IDs) or bundle different customer VLANs into a single service VLAN. Data centers can use
Q-in-Q tunneling and VLAN translation to isolate customer traffic within a single site or
to enable customer traffic flows between cloud data centers in different geographic
locations.
4.3.23.1 Port to Group Mapping
This page allows you to map set of Port members to a Group ID for all switch ports.
