■
In switch X:
•
VLANs assigned to ports X1 - X6 can all be untagged because there is
only one VLAN assignment per port. Red VLAN traffic will go out only
the Red ports; Green VLAN traffic will go out only the Green ports,
and so on. Devices connected to these ports do not have to be 802.1Q-
compliant.
•
However, because both the Red VLAN and the Green VLAN are
assigned to port X7, at least one of the VLANs must be tagged for this
port.
■
In switch Y:
•
VLANs assigned to ports Y1 - Y4 can all be untagged because there is
only one VLAN assignment per port. Devices connected to these ports
do not have to be 802.1Q-compliant.
•
Because both the Red VLAN and the Green VLAN are assigned to port
Y5, at least one of the VLANs must be tagged for this port.
■
In both switches: The ports on the link between the two switches must be
configured the same. That is, the Red VLAN must be untagged on port X7
and Y5 and the Green VLAN must be tagged on port X7 and Y5, or vice-
versa.
N o t e
Each 802.1Q-compliant VLAN must have its own unique VLAN ID number, and
that VLAN must be given the same VLAN ID in every device in which it is
configured. That is, if the Red VLAN has a VLAN ID of 10 in switch X, then 10
must also be used for the Red VLAN ID in switch Y.
