6. Configure the QinQ tunnel uplink port to Tunnel Uplink mode (see
"Adding an Interface to a QinQ Tunnel" on page 173 ).
7. Configure the QinQ tunnel uplink port to join the SPVLAN as a tagged
member (see
"Adding Static Members to VLANs" on page 160 ).

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.

P ARAMETERS
These parameters are displayed:
◆ Tunnel Status – Sets the switch to QinQ mode. (Default: Disabled)
◆ 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. 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 the ethertype field, as they
would be with a standard 802.1Q trunk. Frames arriving on the port
containing any other ethertype are looked upon as untagged frames,
and assigned to the native VLAN of that port.
All ports on the switch will be set to the same ethertype.
W EB I NTERFACE
To enable QinQ Tunneling on the switch:
1.
Click VLAN, Tunnel.
2. Select Configure Global from the Step list.
3. Enable Tunnel Status, and specify the TPID if a client attached to a
tunnel port is using a non-standard ethertype to identify 802.1Q tagged
frames.
4.
Click Apply.
