Figure 9-54. Example of Tagged and Untagged VLAN Port Assignments
I 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:
I
• 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.
I In both switches: The ports on the link between the two switches must be
configured the same. As shown in figure 9-54 (above), 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.
