Function Description
QoS features Traffic
classification
l Traffic classification based on the combination of
the L2 protocol header, IP quintuple information,
outbound port, and 802.1p priority
l Traffic classification based on the C-VID and C-PRI
of QinQ packets
l Matching internal packet information encapsulated
in a GRE tunnel
l Matching internal packet information encapsulated
in a TRILL tunnel
l Matching internal packet information encapsulated
in an MPLS or VXLAN tunnel
Traffic
behavior
l Access control after traffic classification
