Static Virtual LANs (VLANs)
802.1Q VLAN Tagging
■
The VLANs assigned to ports X4 - X6, Y2 - Y5 can all be untagged because
there is only one VLAN assigned per port.
■
Port X1 has two AppleTalk VLANs assigned, which means that one VLAN
assigned to this port can be untagged and the other must be tagged.
■
Ports X2 and Y1 have two port-based VLANs assigned, so one can be
untagged and the other must be tagged on both ports.
■
Ports X3 and Y6 have two port-based VLANs and one protocol-based
VLAN assigned. Thus, one port-based VLAN assigned to this port can be
untagged and the other must be tagged. Also, since these two ports share
the same link, their VLAN configurations must match.

*”No” means the port is not a member of that VLAN. For example, port X3 is not a member of the Red VLAN and does
not carry Red VLAN traffic. Also, if GVRP were enabled (port-based only), “Auto” would appear instead of “No”.
N o t e
VLAN configurations on ports connected by the same link must match.
Because ports X2 and Y5 are opposite ends of the same point-to-point connec
tion, both ports must have the same VLAN configuration; that is, both ports
configure the Red VLAN as “Untagged” and the Green VLAN as “Tagged”.
