Appendix I: Advanced Classifier-Based QoS
Released with software version K.14, the Advanced Classifier-Based QoS provides:
• A finer granularity than globally configured features for classifying network traffic (IPv4 or IPv6)
into classes that can be used in cross-feature software configurations
• Traffic selection based on multiple match criteria:
– IP source address (IPv4 and IPv6)
– IP destination address (IPv4 and IPv6)
– Layer 2 802.1Q VLAN ID
– Layer 3 IP protocol
– Layer 3 IP precedence bits
– Layer 3 DSCP bits
– Layer 4 UDP/TCP application port (including TCP flags)
– VLAN ID
• Additional policy actions to manage selected traffic, such as rate-limiting and IP precedence
marking
• Configuring service policies for features such as quality of service (QoS) and traffic mirroring
• The application of service policies to specific inbound traffic flows on individual port and VLAN
interfaces (rather than only on switch-wide or port-wide traffic)
