classifi- cation failed in classification.

[Service Policy] Click to configure per port egress service policy mode.

Note:
802.1p classification is superior over DSCP classification if both are enabled. That means if
a received packet is classified successfully in 802.1p classification, the classified priority
class is used directly for the packet and the result of DSCP classification is ignored.
