VLANs on Some Ports

The VLANs assigned to ports X3, X4, Y2, Y3, and Y4 can all be untagged because there is only one VLAN assigned per port. Port X1 has multiple VLANs assigned, which means that one VLAN assigned to this port can be untagged and any others must be tagged. The same applies to ports X2, Y1, and Y5.

Switch X			Switch Y
Port	Red VLAN	Green VLAN	Port	Red VLAN	Green VLAN

X1	Untagged	Tagged	Y1	Untagged	Tagged
X2	Untagged	Tagged	Y2	No*	Untagged
X3	No*	Untagged	Y3	No*	Untagged
X4	Untagged	No*	Y4	Untagged	No*
			Y5	Untagged	Tagged

*”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, “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”.
