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'. 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-inQ 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.

Select a unit in the stack to be configured. Specify the ports on which the L2PT to be configured. 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. Specify tunneled protocols on this UNI port. 81

Q-in-Q and VLAN Translation Rules

For ingress untagged packets at UNI ports:

The Switch does not reference the VLAN translation table.

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:

The Switch looks up the VLAN translation table. If matched, the VLAN tag will be translated (replace CEVLAN

with SPVLAN, or add SPVLAN).

Or, check the Switch VLAN tables. The sequence is the same as above. The matched VLAN becomes this

packet’s ‘SPVLAN’.

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.
