User’s Manual of IGS-4215-16T2S
The configuration of promiscuous and isolated ports applies to all private VLANs. When traffic comes in on a promiscuous port
in a private VLAN, the VLAN mask from the VLAN table is applied. When traffic comes in on an isolated port, the private VLAN
mask is applied in addition to the VLAN mask from the VLAN table. This reduces the ports to which forwarding can be done to
just the promiscuous ports within the private VLAN.
The port settings relate to the currently unit, as reflected by the page header. The Port Isolation Configuration screens in Figure
4-3-16 and Figure 4-3-17 appear.
