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)
Web – Click VLAN, 802.1Q VLAN, 802.1Q Tunnel Configuration. Check the Enabled
box, set the TPID of the ports if the client is using a non-standard ethertype to
identify 802.1Q tagged frames, and click Apply.
