ONFIGURING THE
• All ports can send and receive both VLAN-tagged and untagged packets
(i.e. they are hybrid ports)
In the default configuration, any port is able to send traffic to any other
port and a PC connected to any port will be able ro reach the management
interface. Broadcast traffic, for example, will be flooded to all ports on the
switch.
There are three different parameters that can be configured for each port
on the switch; VLAN IDs (VLAN membership), PVID and Packet Type.
Note that the ports within a Trunk cannot be configured individually;
configure the Trunk instead (Trunks are labelled T1 to T8).
Field Attributes
• Port/Trunk – The front-panel port-number of the port or the ID of a
trunk. This cannot be changed.
• VLAN Awareness – VLAN aware ports will strip the VLAN tag from
received frames and insert the tag in transmitted frames (except PVID).
VLAN unaware ports will not strip the tag from received frames or insert
the tag in transmitted frames.
For QinQ application, customer port should be VLAN unaware and
network port (trunk port) should be VLAN aware.
• QinQ – QinQ enabled port will accept packets up to 1526 bytes in
length, which means double tag header frames can be accepted.
For QinQ application, the QinQ should be enabled for provider port but
not for customer port.
Note: For QinQ application, customer ports indicate those ports which
are connected to normal VLAN aware switches at the customer network
and the network ports are those which are connected to the service
provider network. To tunnel the packets through MAN, QinQ needs to
be enabled on network ports
• Packet Type – Sets the interface to accept all frame types, including
tagged or untagged frames, or only tagged frames. When set to receive
all frame types, any received frames that are untagged are assigned to the
default VLAN. PCs should be connected to ports with Packet Type set
5-30
