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.
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
any change.
The packet is forwarded without any change.
The packet is dropped.
The packet is tagged with the VLAN tag corresponding to the
default PVID of the port, and then:
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 remarked with the port priority and
is then forwarded.
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:
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.
Case 2: The VLAN ID in the tag is the default VLAN ID of the
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.
Case 3: The VLAN ID in the tag does not match any VLAN
translation entry on the port. The packet is dropped.
