SAP ingress • Defines up to 16 forwarding class meters and
meter parameters for traffic classification.
• Defines match criteria to map flows to the
meters based on any one of the criteria (IP or
MAC).
Access port • Defines up to 8 forwarding class queues and
queue parameters for traffic classification.
• Maps forwarding classes to the queues.
• Defines FC to remarking values.
• Defines CIR levels and PIR weights that
determines how the queue gets prioritized by
the scheduler.
IP interface Packets are marked using QoS policies on edge
devices. Invoking a QoS policy on a network
port allows for the packets that match the policy
criteria to be remarked.
• Used for classification/marking of MPLS
packets.
• At ingress, defines MPLS LSP-EXP to FC
mapping and 12 meters used by FCs.
• At egress, defines FC to MPLS LSP-EXP
marking.
Ports • Used for classification/marking of IP packets.
• At ingress, defines DSCP or Dot1p to FC
mapping and 8 meters.
• At egress, defines FC to DSCP or Dot1p
marking or both.
Access uplink • Used for classification/marking of IP packets.
ports • At ingress, defines Dot1p to FC mapping and
8 meters.
• At egress, defines FC to Dot1p marking.
