General Configuration Guidelines for QinQ
1. Configure the ECN330-switch to QinQ mode (see “Configuring the
ECN330-switch for Normal Operation or Tunneling Mode” on page 71).
2. Create a Service Provider VLAN, also referred to as an SPVLAN (see
“Creating VLANs” on page 284).
3. Configure the QinQ tunnel port to dot1Q tunnel port mode (see “Adding an
Interface to a QinQ Tunnel” on page 300).
4. Set the Tag Protocol Identifier (TPID) value of the tunnel port. This step is
required is the attached client is using a nonstandard 2-byte ethertype to
identify 802.1Q tagged frames. The standard ethertype value is 0x8100.
(See “Adding an Interface to a QinQ Tunnel” on page 300.)
5. Configure the QinQ tunnel port to join the SPVLAN as an untagged member
(see “Adding Static Members to VLANs (VLAN Index)” on page 287).
6. Configure the SPVLAN ID as the native VID on the QinQ tunnel port (see
“Configuring VLAN Behavior for Interfaces” on page 290).
7. Configure system MTU to 1526 if jumbo frames are not enabled (see
“Configuring the Maximum Frame Size” on page 72).
8. Configure the QinQ uplink port to join the SPVLAN as a tagged member
(see “Adding Static Members to VLANs (VLAN Index)” on page 287).
Adding an Interface to a QinQ Tunnel
Follow the guidelines in the preceding section to set up a QinQ tunnel on the
ECN330-switch. Use the VLAN Port Configuration or VLAN Trunk Configuration
page 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 page to set the ECN330-switch to QinQ mode
before configuring a tunnel port (see “Configuring the ECN330-switch
for Normal Operation or Tunneling Mode” on page 71).
• Use the TPID field to set a custom 802.1Q ethertype value on the
selected interface. This feature allows the ECN330-switch to
interoperate with third-party switches that do not use the standard
0x8100 ethertype to identify 802.1Q-tagged frames. For example,
