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 to access 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 ID (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).
IEEE 802.1Q Tunneling (QinQ) is designed for service providers carrying
traffic for multiple customers across their networks. QinQ tunneling is
used to maintain customer-specific VLAN configurations even when
different customers use the same internal VLAN IDs. This is
accomplished by inserting Service Provider VLAN (SPVLAN) tags into
the customer’s frames when they enter the service provider’s network, and
then stripping the tags when the frames leave the network. QinQ tunneling
expands VLAN space by using this VLAN-in-VLAN hierarchy, preserving
the customer’s original tagged packets, and adding SPVLAN tags to each
frame (also called double tagging). Ports on the switch can be set to
support QinQ when providing a direct link to a service provider's network.
Field Attributes
• Port/Trunk
– The 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 operation, a customer port should be set to VLAN unaware
and a provider port (trunk port) should be set to VLAN aware.
• QinQ
– A QinQ enabled port will accept packets up to 1526 bytes in
length, which means double tag header frames can be accepted.
QinQ should be enabled for provider ports but not for customer ports.
