stripped when the packets are sent out. Another reason is that it
causes non-customer packets to be forwarded to the SPVLAN.
•
Static trunk port groups are compatible with QinQ tunnel ports as long
as the QinQ configuration is consistent within a trunk port group.
•
The native VLAN (VLAN 1) is not normally added to transmitted frames.
Avoid using VLAN 1 as an SPVLAN tag for customer traffic to reduce the
risk of misconfiguration. Instead, use VLAN 1 as a management VLAN
instead of a data VLAN in the service provider network.
•
There are some inherent incompatibilities between Layer 2 and Layer 3
switching:
•
Tunnel ports do not support IP Access Control Lists.
•
Layer 3 Quality of Service (QoS) and other QoS features containing
Layer 3 information are not supported on tunnel ports.
•
Spanning tree bridge protocol data unit (BPDU) filtering is
automatically disabled on a tunnel port.
General Configuration Guidelines for QinQ
1.
Enable Tunnel Status, and set the Tag Protocol Identifier (TPID) value of
the tunnel access port (in the Ethernet Type field. This step is required
if the attached client is using a nonstandard 2-byte ethertype to
identify 802.1Q tagged frames. The default ethertype value is 0x8100.
(See “Enabling QinQ Tunneling on the Switch” on page 163 .)
2.
Create a Service Provider VLAN, also referred to as an SPVLAN (see
“Configuring VLAN Groups” on page 150 ).
3.
Configure the QinQ tunnel access port to Access mode (see “Adding an
Interface to a QinQ Tunnel” on page 167 ).
4.
Configure the QinQ tunnel access port to join the SPVLAN as an
untagged member (see
“Adding Static Members to VLANs” on
page 153 ).
5.
Configure the SPVLAN ID as the native VID on the QinQ tunnel access
port (see
“Adding Static Members to VLANs” on page 153 ).
6.
Configure the QinQ tunnel uplink port to Uplink mode (see “Adding an
Interface to a QinQ Tunnel” on page 167 ).
7.
Configure the QinQ tunnel uplink port to join the SPVLAN as a tagged
member (see
“Adding Static Members to VLANs” on page 153 ).

Use the VLAN > Tunnel (Configure Global) page to configure the switch to
operate in IEEE 802.1Q (QinQ) tunneling mode, which is used for passing
Layer 2 traffic across a service provider’s metropolitan area network. You
can also globally set the Tag Protocol Identifier (TPID) value of the tunnel
