Figure 2-8 Configuring the DSCP to 802.1p Mapping and the DSCP Remap
Follow these steps to configure the DSCP Priority:
1) Select the desired port, configure the DSCP to 802.1p mapping and the DSCP remap.
DSCP Priority Displays the number of DSCP priority. DSCP Priority is used to classify the
packets based on the value of DSCP, and map them to different queues. ToS
(Type of Service) is a part of IP header, and DSCP uses the first six bits of ToS to
represent the priority of IP packets. The DSCP values range from 0 to 63.
802.1p Priority Specify the DSCP to 802.1p mapping for the desired port. The ingress packets
are first mapped to 802.1p priority, then to TC queues according to the 802.1p to
queue mappings.
DSCP Remap (Optional) Select the DSCP priority to which the desired DSCP priority will be
remapped for the port. When the switch detects the packets with desired DSCP
value, it will modify the packets’ DSCP value according to the map.
2) Click Apply.
