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 switch VLAN tables. The sequence: mac-based VLAN -> subnet-based VLAN -> protocl-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 will look up the VLAN translation table. If matched, the VLAN tag will be translated (replace
CEVLAN with SVLAN, or add SPVLAN).
2. Otherwise, check switch VLAN tables. The sequence is the same as above. The matched VLAN will become
this packet's 'SPVLAN'.
