24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
Configuration Examples User Manual412
• If the port is a member of the VLAN specified by the packet’s VLAN ID, the packet can be
sent to other ports with the same VLAN ID.
• 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 configuration examples
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. On the Basic VLAN Configuration page (see Configure VLANs on page 140), create the
following VLANs:
• A VLAN with VLAN ID 10.
• A VLAN with VLAN ID 20.
2. On the VLAN Membership page (see
Configure VLAN membership on page 144) 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: po
rt 4 (U), port 5 (T),
and port 6 (U).
3. On the Port PVID Configuration page (see
Configure the port PVID settings on
page 147), specify the PVID for ports g1 and g4 so that packets entering these ports are
tagged with the port VLAN ID:
• Port g1: PVID 10
• Port g4: 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 VL
AN ID 10.
The packet
can
access 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 can access 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.
