Isolated ports
— Ports from which traffic can only be forwarded to promiscuous ports in the private VLAN
— Ports which can receive traffic from only promiscuous ports in the private VLAN
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.
This page is used for enabling or disabling port isolation on ports in
other isolated ports on the same VLAN and Private VLAN. The Port Isolation screen in
Figure 4-6-7
appears.
