L2 Functions > MAC Address Table > Static MAC
This feature provides two distinct functions. The MAC Address 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 disabled.
Figure 4.61 – L2 Functions > MAC Address Table > Static Mac Address
The Static MAC Address Lists table displays the static MAC addresses connected, as well as the VID.
Add Static MAC Address: you 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 MAC Address 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.

L2 Functions > Spanning Tree > STP Global Settings
The Switch implements three versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol
(RSTP) as defined by the IEEE 802.1w specification and a version compatible with the IEEE 802.1D STP as
defined by the IEEE802.1 specification. RSTP can operate with legacy equipment implementing IEEE
802.1D, however the advantages of using RSTP will be lost.
