IEEE 802.1Q Tunneling
– 204 –
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 204.)
2. Create a Service Provider VLAN, also referred to as an SPVLAN (see
"Configuring VLAN Groups" on page 190).
3. Configure the QinQ tunnel access port to Access mode (see "Adding an
Interface to a QinQ Tunnel" on page 207).
4. Configure the QinQ tunnel access port to join the SPVLAN as an
untagged member (see "Adding Static Members to VLANs" on
page 193).
5. Configure the SPVLAN ID as the native VID on the QinQ tunnel access
port (see "Adding Static Members to VLANs" on page 193).
6. Configure the QinQ tunnel uplink port to Uplink mode (see "Adding an
Interface to a QinQ Tunnel" on page 207).
7. Configure the QinQ tunnel uplink port to join the SPVLAN as a tagged
member (see "Adding Static Members to VLANs" on page 193).
ENABLING QINQ
TUNNELING ON THE
SWITCH
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
port if the attached client is using a nonstandard 2-byte ethertype to
identify 802.1Q tagged frames.

PARAMETERS
These parameters are displayed:
u Tunnel Status – Sets the switch to QinQ mode. (Default: Disabled)
u Ethernet Type – The Tag Protocol Identifier (TPID) specifies the
ethertype of incoming packets on a tunnel port. (Range: hexadecimal
0800-FFFF; Default: 8100)
Use this field to set a custom 802.1Q ethertype value for the 802.1Q
Tunnel TPID. This feature allows the switch to interoperate with third-
party switches that do not use the standard 0x8100 ethertype to
identify 802.1Q-tagged frames. For example, if 0x1234 is set as the
custom 802.1Q ethertype on a trunk port, incoming frames containing
that ethertype are assigned to the VLAN contained in the tag following
