VLAN Configuration
Interface to a QinQ Tunnel" on page 11-17.)
3. Create a Service Provider VLAN, also referred to as an SPVLAN (see "Creating
VLANs" on page 11-6).
4. Configure the QinQ tunnel access port to 802.1Q Tunnel mode (see "Adding an
Interface to a QinQ Tunnel" on page 11-17).
5. Configure the QinQ tunnel access port to join the SPVLAN as an untagged
member (see "Adding Static Members to VLANs (VLAN Index)" on page 11-8).
6. Configure the SPVLAN ID as the native VID on the QinQ tunnel access port (see
"Configuring VLAN Behavior for Interfaces" on page 11-10).
7. Configure the QinQ tunnel uplink port to 802.1Q Tunnel Uplink mode (see
"Adding an Interface to a QinQ Tunnel" on page 11-17).
8. Configure the QinQ tunnel uplink port to join the SPVLAN as a tagged member
(see "Adding Static Members to VLANs (VLAN Index)" on page 11-8).

Enabling QinQ Tunneling on the Switch

The switch can be configured to operate in normal VLAN mode or 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.
Command Usage
• Use the TPID field to set a custom 802.1Q ethertype value on the selected
interface. 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.
Command Attributes
• 802.1Q Tunnel Status – Sets the switch to QinQ mode, and allows the QinQ
tunnel port to be configured. The default is for the switch to function in normal
mode.
• 802.1Q Ethernet Type – The Tag Protocol Identifier (TPID) specifies the ethertype
of incoming packets on a tunnel port. (Range: hexadecimal 0800-FFFF;
Default: 8100)
