Classifier-based QoS

Starting in release K.14.01, classifier-based QoS operation provides additional QoS actions on a per-port and per-VLAN basis.

• Classifier-based match criteria on inbound IPv4/IPv6 traffic include:

  • IP source address (IPv4 and IPv6)

  • IP destination address (IPv4 and IPv6)

  • IP protocol (such as ICMP or SNMP)

  • Layer 3 IP precedence bits

  • Layer 3 DSCP codepoint

  • Layer 4 Source and Destination UDP/TCP application port

  • VLAN ID

• Classifier-based QoS policy actions on matching IPv4/IPv6 packets are as follows:

  • Setting Layer 2 802.1p priority value (class of service) in VLAN-tagged and untagged packet headers

  • Setting the Layer 3 IP precedence bits

  • Setting the Layer 3 Differentiated-Services Codepoint (DSCP) bits

  • Rate limiting inbound traffic on port and VLAN interfaces
