The following table describes the labels in this screen.
14.18 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.
Table 288 Switch Port Setup: Broadcast
LABEL DESCRIPTION
Port This is the label of a Gigabit Ethernet interface.
Broadcast Select Enable to limit the number of broadcast packets the interface will accept per
second.
Type how many broadcast packets the interface should accept per second (0~262143).
Multicast Select Enable to limit the number of multicast packets the interface will accept per
second.
Type how many multicast packets the interface should accept per second (0~262143).
Unknown Unicast 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.
Type how many unknown unicast packets the interface should accept per second
(0~262143).
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The
system loses these changes if it is turned off or loses power, so use the Config Save link
on the navigation panel and then the Save button to save your changes to the non-
