Chapter 8 Basic Setting 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 802.1Q or Port Based in the VLAN Type field in this screen. Refer to the chapter on VLAN. Figure 30 Basic Setting > Switch Setup The following table describes the labels in this screen. Table 11 Basic Setting > Switch Setup LABEL 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 Chapter 9 on page 97 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. MAC Address Learning 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 reduces outgoing traffic broadcasts. For MAC address learning to occur on a port, the port must be active.
