L2 Functions > MAC Address Table > Static MAC
This feature provides two distinct functions. The
Disable Auto Learning
table allows turning off the function
of learning MAC address automatically, if a port isn't specified as an uplink port (for example, connects to a
DHCP Server or Gateway). By default, this feature is Off (disabled).
Figure 5.41 – L2 Functions > MAC Address Table > Static Mac Address
To initiate the removal of auto-learning for any of the uplink ports, click
On
to enable this feature, and then
select the port(s) for auto learning to be disabled.
The
Static MAC Address Lists
table displays the static MAC addresses connected, as well as the VID.
Click
Add
to add a new MAC address, you also need to select the assigned Port number. Enter both the
Mac Address and VID, and then Click
Add
. Click
Delete
to remove one entry or click
Delete all
to clear the
list.
By disabling Auto Learning capability and specifying the static MAC addresses, the network is protected from
potential threats like hackers, because traffic from illegal MAC addresses will not be forwarded by the Switch.
L2 Functions > MAC Address Table > Dynamic Forwarding Table
For each port, this table displays the MAC address learned by the Switch. To add a MAC address to the
Static Mac Address List, click the
Add
checkbox, and then click
Apply
associated with the identified address.
