Ruijie RG-S2900G-E Series - Configuring Basic Qinq

Configuration Guide QinQ Configuration
 Once QinQ is enabled on a port, to enable IGMP Snooping, you need set
SVGL sharing mode or otherwise IGMP Snooping does not function on the
port with QinQ enabled.
Configuring Basic QinQ
In the global configuration mode, input the interface command to enter the
interface configuration mode. Follow these steps to configure a tunnel port:
Command
Function
configure terminal
Enter the global configuration mode.
interface <interface>
Enter the interface configuration mode.
switchport mode dot1q-tunnel
Set the port as a dot1q-tunnel port.
switchport dot1q-tunnel allowed vlan
[add] { tagged | untagged } v_list
Add the allowed VLAN for dot1q-tunnel
port and specify that whether the VLAN is
tagged or not when outputting the packets
of allowed VLAN.
switchport dot1q-tunnel allowed vlan
remove v_list
Delete the allowed VLAN on the
dot1q-tunnel port.
switchport dot1q-tunnel native vlan
VID
Set the default VLAN for the dot1q-tunnel
port.
End
Exit the interface mode.
show running-config
Show the configuration.
Note
It is not recommended to set the native VLAN of trunk port in the
ISP network as the default VLAN of tunnel port, because the tag
with native VID will be stripped off on trunk port.
The following example demonstrates how to configure a QinQ port:
Ruijie(config)# interface fastEthernet 0/1
Ruijie(config-if)# switchport mode dot1q-tunnel
Ruijie(config-if)# switchport dot1q-tunnel nativ vlan 20
Ruijie(config-if)# switchport dot1q-tunnel allowed vlan tagged 100-200
Ruijie(config)# end
