P ARAMETERS
These parameters are displayed:
◆ DSCP – DSCP value in ingress packets. (Range: 0-63)
◆ Trust – Controls whether a specific DSCP value is trusted. Only frames
with trusted DSCP values are mapped to a specific QoS class and drop
level (DPL). Frames with untrusted DSCP values are treated as non-IP
frames.
◆ QoS Class – QoS value to which the corresponding DSCP value is
classified for ingress processing. (Range: 0-7; Default: 0)
◆ DPL – Drop Precedence Level to which the corresponding DSCP value is
classified for ingress processing. (Range: 0-1, where 1 is the higher
drop priority; Default: 0)
