A DSCP or dot1p classification policy must be associated with a SAP ingress QoS policy or an Ethernet port to map flows to an FC and profile for IP traffic received on SAP ingress.
The dscp-classification policy-id or dot1p-classification policy-id value identifies which classification policy is used to match IP packets and map the IP DSCP or dot1p to an FC and profile. The no form of the dscp-classification or dot1p-classification command associates the default classification policy (policy 1). The default policy maps all IP DSCP or dot1p values to FC ‟be” and profile ‟out”. If a packet does not match any explicitly configured criteria in the policy, the default-fc mapping is used. For details about Layer 2 and Layer 3 scenarios, see IP DSCP and dot1p classification policy support.
