All self-generated traffic is assigned into forwarding class NC by default.

Ingress self-generated traffic is stored in CPM queues and egress self-generated traffic is stored in IOM queues.

The self-generated packets will be marked with a default DSCP value.

The self-generated packets will be marked with default EXP bits.

Policer 3 forwards packets as out-of-profile when its PIR bucket has 4000 tokens.

Policer 3 starts discarding low-priority packets when its PIR bucket has at least 3000 tokens.

Policer 4 forwards all its packets as out-of-profile.

Policer 4 starts discarding low-priority packets when its PIR bucket has at least 3000 tokens.

The first 3 bits of the DSCP value are copied directly into the EXP field on the first network egress.

The EXP bits are set on the first network egress, based on a combination of the SAP-ingress classification and the network policy applied.

The 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.

The EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.
