Smart Switch Software User Manual GS748T 4. The following situations produce results as described: • If an untagged packet enters Port 1, the switch tags it with a VLAN tag value 10. The packet has access to Port 2 and Port 3. The outgoing packet is stripped of its tag to leaves Port 2 as an untagged packet. For Port 3, the outgoing packet leaves as a tagged packet with a VLAN tag value of 10. • If a tagged packet with a VLAN tag value 10 enters Port 3, the packet has access to Port 1 and Port 2. If the packet leaves Port 1 and/or Port 2, it is stripped of its tag to leave the switch as an untagged packet. • If an untagged packet enters Port 4, the switch tags it with a VLAN tag value 20. The packet will have access to Port 5 and Port 6. The outgoing packet is stripped of its tag to become an untagged packet as it leaves Port 6. For Port 5, the outgoing packet leaves as a tagged packet with a VLAN tag value of 20. Port-based VLANs Port-based VLANs help to confine broadcast traffic to the switch ports. This switch allows up to 26 port-based VLAN group, Any one port can belong to different VLAN groups. The default VLAN group is a port-based VLAN that has all ports belonging to VLAN 1. Packets received by the switch are treated in the following way: • When a packet enters a port, it can only proceed to ports with the same VLAN membership as that ingress port. • If a port on the switch does not have a common VLAN membership with the source port, the packet is dropped. Port-based VLAN Example Configuration This example basically demonstrates how the port-based VLANs work to meet your needs. Setup the following VLANs, each with defined descriptions: • VLAN 1 (IT department) • VLAN 2 (Sales department) • VLAN 3 (Marketing department) • VLAN 4 (Accounting department). • Configure the VLAN membership. Be sure to set all of them as follows. • Setting up second VLAN group (Sales), VLAN ID = 02, with membership of ports 1~8, 25. Virtual Local Area Networks (VLANs) B-3 v1.0, October 2007

The following situations produce results as described:
•
If an untagged packet enters Port 1, the switch tags it with a VLAN tag value 10. The
packet has access to Port 2 and Port 3. The outgoing packet is stripped of its tag to leaves
Port 2 as an untagged packet. For Port 3, the outgoing packet leaves as a tagged packet
with a VLAN tag value of 10.
•
If a tagged packet with a VLAN tag value 10 enters Port 3, the packet has access to Port 1
and Port 2. If the packet leaves Port 1 and/or Port 2, it is stripped of its tag to leave the
switch as an untagged packet.
•
If an untagged packet enters Port 4, the switch tags it with a VLAN tag value 20. The
packet will have access to Port 5 and Port 6. The outgoing packet is stripped of its tag to
become an untagged packet as it leaves Port 6. For Port 5, the outgoing packet leaves as a
tagged packet with a VLAN tag value of 20.
Port-based VLANs
Port-based VLANs help to confine broadcast traffic to the switch ports. This switch allows up to
26 port-based VLAN group, Any one port can belong to different VLAN groups. The default
VLAN group is a port-based VLAN that has all ports belonging to VLAN 1.
Packets received by the switch are treated in the following way:
•
When a packet enters a port, it can only proceed to ports with the same VLAN membership as
that ingress port.
•
If a port on the switch does not have a common VLAN membership with the source port, the
packet is dropped.
Port-based VLAN Example Configuration
This example basically demonstrates how the port-based VLANs work to meet your needs.
Setup the following VLANs, each with defined descriptions:
•
VLAN 1 (IT department)
•
VLAN 2 (Sales department)
•
VLAN 3 (Marketing department)
•
VLAN 4 (Accounting department).
•
Configure the VLAN membership. Be sure to set all of them as follows.
•
Setting up second VLAN group (Sales), VLAN ID = 02, with membership of ports 1~8, 25.
