FS728TP Smart Switch Software Administration Manual
• Packets leaving the switch are either tagged or untagged, depending on the setting for
that port’s VLAN membership properties. A U for a given port means that packets leaving
the switch from that port are untagged. Inversely, a T for a given port means that packets
leaving the switch from that port are tagged with the VLAN ID that is associated with the
port.
The example given in this section comprises numerous steps to illustrate a wide range of
configurations to help provide an understanding of tagged VLANs.
VLAN Example Configuration
This example demonstrates several scenarios of VLAN use and describes how the switch
handles tagged and untagged traffic.
In this example, you create two new VLANs, change the port membership for default
VLAN
1, and assign port members to the two new VLANs:
1. In the Basic VLAN Configuration screen (see VLAN Configuration on page 82), create
the following VLANs:
• A VLAN with VLAN ID 10.
• A VLAN with VLAN ID 20.
2. In the VLAN Membership screen (see VLAN Membership Configuration on page 83)
specify the VLAN membership as follows:
• For the default VLAN with VLAN ID 1, specify the following members: port 7 (U) and
port 8 (U).
• For the VLAN with VLAN ID 10, specify the following members: port 1 (U), port 2 (U),
and port 3 (T).
• For the VLAN with VLAN ID 20, specify the following members: port 4 (U), port 5 (T),
and port 6 (U).
3. In the Port PVID Configuration screen (see Port VLAN ID Configuration on page 84),
specify the PVID for ports e1 and e4 so that packets entering these ports are tagged with
the port VLAN ID:
• Port e1: PVID 10
• Port e4: PVID 20
4. With the VLAN configuration that you set up, the following situations produce results as
described:
• If an untagged packet enters port 1, the switch tags it with VLAN ID 10. The packet
has access to port 2 and port 3. The outgoing packet is stripped of its tag to leave port
2 as an untagged packet. For port 3, the outgoing packet leaves as a tagged packet
with VLAN ID 10.
• If a tagged packet with VLAN ID 10 enters port 3, the packet has access to port 1 and
port 2. If the packet leaves port 1 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 VLAN ID 20. The packet
has 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 VLAN ID 20.
