IEEE 802.1Q Virtual Local Area Network (VLAN) B-3
July 2005
• Default VLAN: Port 7 – Port 26 (all U), VID = 1
• VLAN 1: Port 1 (U), Port 2 (U), Port 3 (T), VID = 10
• VLAN 2: Port 4 (U), Port 5 (T), Port 6 (U), VID = 20.
4. The following scenarios will produce results as described below:
(1). If an untagged packet enters Port 1, the switch will tag it with a VLAN tag value 10. The
packet will have access to Port 2 and Port 3. The outgoing packet will be stripped away its tag
becoming an untagged packet as it leaves Port 2. For Port 3, the outgoing packet will leave as
a tagged packet with a VLAN tag value 10.
(2). If a tagged packet with a VLAN tag value 10 enters Port 3, the packet will have access to
Port 1 and Port 2. If the packet leaves Port 1 and/or Port 2, it will be stripped away its tag
becoming an untagged packet as it leaves switch.
(3). If an untagged packet enters Port 4, switch will tag it with a VLAN tag value 20. The
packet will have access to Port 5 and Port 6. The outgoing packet will be stripped away its tag
becoming an untagged packet as it leaves Port 6. For Port 5, the outgoing packet will leave as
a tagged packet with a VLAN tag value 20.
