13.18 Switch Port Setup DSCP

DSCP (Differentiated Services Code Point) is a field in the header of IP packets for packet
classification purposes. The QoS (Quality-of-Service) in the Device uses DSCP to provide different
level of services and priorities for downstream data transmission.
IEEE 802.1p lets the system transmit frames according to their 3-bit priority (0~7) in an IEEE
802.1q header. Frames with higher priority are served first. This system allows you to overwrite the
DSCP level of service with an IEEE 802.1p priority for downstream traffic.

Select Enable to limit the number of unknown unicast packets the interface will accept
per second. Unknown unicast packets are also known as destination lookup failure (DLF)
packets.
