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
