z In the case of traffic classification based on the source MAC
address/destination MAC address, Ethernet priority, VLAN
ID, or physical port, if the packet matches the configured
traffic classification rule, the packet is priority-remarked with
the value specified in the rule and is then forwarded;
otherwise, the packet is directly forwarded.
z In the case of traffic classification based on Ethernet type,
DSCP, IP protocol type, source IP address/destination IP
address, or source L4 port, the packet is forwarded without

With VLAN tag
Case 1: The VLAN ID in the VLAN tag matches a VLAN
translation entry on the port. The VLAN ID is replaced with the
VLAN ID corresponding to the entry, and then:
z If the packet matches the configured traffic classification
rule, the packet is priority-remarked with the value specified
in the rule and is then forwarded;
z Otherwise, the packet is directly forwarded.
Case 2: The VLAN ID in the tag is the default VLAN ID of the
port:
z If the packet matches the configured traffic classification
rule, the packet is priority-remarked with the value specified
in the rule and is then forwarded;
z Otherwise, the packet is directly forwarded.
Case 3: The VLAN ID in the tag does not match any VLAN
