You should enable RSTP or MRSTP before you can use smart isolation on the Switch. If the network
topology changes, the Switch automatically updates the isolated port list with the latest designated
port information.
Note: The uplink port connected to the Internet should be the root port. Otherwise, with
smart isolation enabled, the isolated ports cannot access the Internet.
8.5 Switch Setup
Click Basic Setting > Switch Setup in the navigation panel to display the screen as shown. The
VLAN setup screens change depending on whether you choose

or
Port Based
in the VLAN

DESCRIPTION
VLAN Type
Choose 802.1Q or Port Based. The VLAN Setup screen changes depending on whether
you choose 802.1Q VLAN type or Port Based VLAN type in this screen. See
for more information.
Smart Isolation
Select Active to enable smart isolation on the Switch. The designated port(s) then
becomes the isolated port. Smart isolation allows you to prevent isolated ports on different
switches from transmitting traffic to each other.
Note: To use smart isolation, you should have configured 802.1Q VLAN port isolation or
private VLAN and (M)RSTP on the Switch. Smart isolation does not work with MSTP
and/or port-based VLAN.
MAC Address
Learning
MAC address learning reduces outgoing traffic broadcasts. For MAC address learning to
occur on a port, the port must be active.
