Table 4: QoS Policy Types and Descriptions
Policy Type Applied at… Description Page
Service Ingress SAP ingress • Defines up to 32 forwarding class queues and
queue parameters for traffic classification
• Defines up to 31 multipoint service queues for
broadcast, multicast and destination unknown
traffic in multipoint services
• Defines match criteria to map flows to the
queues based on combinations of customer
QoS (IEEE 802.1p/DE bits, DSCP, TOS
Precedence), IP criteria or MAC criteria

Network Router interface • Used for classification/marking of IP and
MPLS packets
• At ingress, defines DSCP, Dot1p MPLS LSP-
EXP and IP criteria classification to FC
mapping
• At ingress, defines FC to policer/queue-group
queue mapping
• At egress, defines DSCP or prec FC mapping
• At egress, defines FC to policer/queue-group
queue mapping
• At egress, defines DSCP, MPLS LSP-EXP and
Dot1p/DE marking
