Switching Commands
87
ProSafe Managed Switch
primary VLAN can be configured per private VLAN. All ports within a private VLAN share
the same primary VLAN.
Isolated VLAN—A secondary VLAN that carries traffic from isolated ports to promiscuous
ports. Only one isolated VLAN can be configured per private VLAN.
Community VLAN—A secondary VLAN that forwards traffic between ports that belong to
the same community and the promiscuous ports. There can be multiple community
VLANs per private VLAN.
Three types of port designations exist within a private VLAN:
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.
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.
Community Ports—An endpoint connected to a community port is allowed to
communicate with the endpoints within a community and with any configured
promiscuous port. The endpoints that belong to one community cannot communicate with
endpoints that belong to a different community or with endpoints connected to isolated
ports.
The Private VLANs can be extended across multiple switches through inter-switch/stack links
that transport primary, community and isolated VLANs between devices.
