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
■Ports X3 and Y6 have two

|
|
|
| configure the Red VLAN as “Untagged” and the Green VLAN as “Tagged”. | |||||||
