5.17 DSCP Screens

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

DESCRIPTION
Turn on anti-MAC spoofing to have the system check for hosts with fake or
duplicated MAC addresses which attempt to access the system.
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 on the navigation panel and then the Save button to save your changes to the
non-volatile memory when you are done configuring.
Click Cancel to begin configuring the screen again.
