CHAPTER 58
VLAN Isolation
This chapter shows you how to configure the Switch to prevent communications between ports in a
VLAN.
58.1 VLAN Isolation Overview
VLAN Isolation allows you to do port isolation within a VLAN in a simple way. You specify which ports in a
VLAN is not isolated by adding it to the promiscuous port list. The Switch automatically adds other ports
in this VLAN to the isolated port list and blocks traffic between the isolated ports. A promiscuous port can
communicate with any port in the same VLAN. An isolated port can communicate with the promiscuous
ports only.
Note: You can have up to one VLAN Isolation rule for each VLAN.
Figure 350 VLAN Isolation Example
Note: Make sure you keep at least one port in the promiscuous port list for a VLAN with VLAN
Isolation enabled. Otherwise, this VLAN is blocked from the whole network.
