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.
