Adding an Interface to a QinQ Tunnel
Follow the guidelines in the preceding section to set up a QinQ tunnel on the switch.
Use the VLAN Port Configuration or VLAN Trunk Configuration screen to set the
ingress port on the edge switch to dot1Q tunnel mode. Also 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 System Mode screen to set the switch to QinQ mode before configuring a
tunnel port (see “Configuring the Switch for Normal Operation or Tunneling Mode”
on page 4-3).
• 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, 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 members of a VLAN should be set to the same ethertype.
Command Attributes
• Mode – Set the VLAN membership mode dot1Q-Tunnel. (Default: Hybrid)
- Dot1q-Tunnel – Configures IEEE 802.1Q tunneling (QinQ) to segregate and
preserve customer VLAN IDs for traffic crossing the service provider network.
• TPID (0-65535) – Tag Protocol Identifier specifies the ethertype of incoming
packets on a tunnel port.
Web – Click VLAN, 802.1Q VLAN, Port Configuration or Trunk Configuration. Set
the mode for the tunnel port to Dot1q-Tunnel, and set the TPID if the client is using a
non-standard ethertype to identify 802.1Q tagged frames, then click Apply.
