Outlines how QoS is applied in different deployment scenarios by combining classification, remarking, queuing, and policy propagation methods. Helps you choose suitable approaches for VPWS traffic, BGP-based classification, PWHE handling, and BVI two-pass processing.
Information flow
Introduces the QoS information flow across network scenarios, showing how classification, marking, queuing, policing, shaping, and forwarding behavior interact across QoS-enabled traffic paths.
QoS support for VPWS traffic
This section explains how QoS is applied to Virtual Private Wire Service (VPWS) traffic by using Layer 2 header fields for traffic classification and differentiation.
QoS Policy Propagation via BGP
Enables classification and marking of traffic based on BGP route attributes, allowing QoS policies to be applied according to routing information.
QoS on Pseudowire Headend
Details QoS on PWHE interfaces, including traffic mapping, marking, policing, queuing, aggregate shaping, policy options, limitations, and configuration procedures for flat and hierarchical QoS.
QoS on BVI
Explains how QoS policies operate on bridged virtual interfaces in a two-pass forwarding model and identifies the release-specific capabilities available for Layer 2-to-Layer 3 and Layer 3-to-Layer 2 traffic flows.
Egress feature capability
Explains the egress traffic processing capability that enables supported egress QoS features.
