Primary Pvlans - Siemens SCALANCE XM-400 Configuration Manual

Note
VLAN ID with secondary PVLANs
If you use the same VLAN ID for secondary PVLANs on different IE switches, the end devices
in these secondary PVLANs can communicate with other via layer 2 across the different
switches.
PC1
Secondary PVLAN 10
Isolated
In this example, the ports of the IE switches that connect them to other IE switches are
promiscuous ports. These network ports are tagged members in all PVLANs: Primary PVLAN
and all secondary PVLANs.
The ports to which the PCs are connected are host ports. The host ports are all untagged
members in the primary PVLAN and in their secondary PVLAN.
The port to which the server is connected is a promiscuous port. This promiscuous port ports
is an untagged member in all PVLANs: Primary PVLAN and all secondary PVLANs.
In this example all PCs can communicate with the server. The server can communicate with
all PCs. PC1 cannot communicate with any other PC. The PCs within a community secondary
PVLAN can communicate with each other but not with the PCs in another secondary PVLAN.
