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-base d 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 m atched, 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 abov e. The m atched VLAN will b ecome
this packet's 'SPVLAN'.
