Figure 20-3. Private VLAN Domain
Promiscuous Ports
An endpoint connected to a promiscuous port is allowed to communicate
with any endpoint within the private VLAN. Multiple promiscuous ports can
be defined for a single private VLAN domain.
In the configuration shown in Figure 20-3, the port connected from SW1 to
R1 (TE1/1/1) is configured as a promiscuous port. It is possible to configure a
port-channel as a promiscuous port in order to provide a level of redundancy
on the private VLAN uplink.
Isolated Ports
An endpoint connected to an isolated port is allowed to communicate with
endpoints connected to promiscuous ports only. Endpoints connected to
adjacent isolated ports cannot communicate with each other.
