DES-7200 Configuration Guide Chapter 12 QinQ Configuration
12-34
DES-7200(config)# interface gigabitEthernet 0/3
DES-7200(config-if-GigabitEthernet 0/3)#switchport mode uplink
Note
Outer Tag VLAN (including Native VLAN) shall be allowed on
Tunnel port, and packets of such VLAN shall be allowed to pass
the Internet-accessing interface. In this example, the Native
VLAN of Tunnel port is the default VLAN1, which is allowed by
default.
12.3.3.5 Verification
Step 1: Verify whether the configurations of Tunnel port are correct. Key points:
whether the interface type is dot1q-tunnel, whether the outer Tag VLAN is
included in the allowed VLAN list of the interface, and whether the policy on the
interface has been properly configured.

Step 2: Verify the QinQ configuration of respective ports again. Key points are
the same as Step 1.
