Q-in-Q and VLAN Translation Rules:
For Ingress untagged packets at UNI ports:
1. The Switch does not reference the VLAN translation table.
2. Check the Switch VLAN tables. The Sequence is MAC-based VLAN -> subnet-based VLAN ->
protocol-based VLAN -> port-based VLAN. If matched, the matched VLAN will become this packet’s
SPVLAN.
For Ingress tagged packets at UNI ports:
1. The Switch looks up the VLAN translation table. If matched, the VLAN tag will be translated
(replace CEVLAN with SPVLAN, or add SPVLAN).
2. Or, check the Switch VLAN tables. The sequence is the same as above. The matched VLAN
becomes this packet’s SPVLAN.
Configuration > Layer 2 Protocol Tunneling Settings
The layer 2 protocol tunneling is used to tunnel the layer 2 protocol packets. When the device is operating
with the Q-in-Q enabled, DA will be replaced by the tunnel multicast address, and the BPDU will be tagged
with the tunnel VLAN based on the QinQ VLAN configuration and the tunnel/uplink setting. When the device
is operating with the Q-in-Q disabled, the BPDU will have its DA replaced by the tunnel multicast address
and is transmitted out based on the VLAN configuration and the tunnel/uplink setting.
Figure 4.67 - Configuration > Layer2 Protocol Tunneling Settings
Layer 2 Protocol Tunneling State:
Specify to enable or disable the layer 2 Protocol Tunneling of ports.
From Port / To Port:
A consecutive group of ports that are part of the configuration starting with the selected
port.
Type:
Specify the layer 2 protocol tunnel type which will apply on the specified ports.
UNI –
Specify the port is UNI port.
NNI –
Specify the port is NNI port.
None –
Disable the tunneling function.
Tunneled Protocol:
Specify tunneled protocols on this UNI port.
STP –
Specify the BPDU received on these UNI will be tunneled.
GVRP –
Specify the GVRP PDU received on these UNI will be tunneled.
Protocol MAC –
Specify the destination MAC address of the L2 protocol packets that will tunneled
on these UNI ports. The MAC address can be 01-00-0C-CC-CC-CC or 01-00-0C-CC-CC-CD.
All –
Specify all supported.
Threshold (0-65535):
Specify the drop threshold for packets-per-second accepted on this UNI port. The port
drops the PDU if the protocol’s threshold is exceeded. The range of the threshold value is 0 to 65535
(packet/second). The value 0 means unlimited. By default, the value is 0.
