Traffic Groupings
A traffic grouping is a classification of traffic that has one or more attributes in common. Traffic is
typically grouped based on the applications discussed starting on page 106.
Traffic groupings are separated into the following categories for discussion:
• IP-based information, such as IP source/destination and TCP/UDP port information
• Destination MAC (MAC QoS groupings)
• Explicit packet class of service information, such as 802.1p or DiffServ (IP TOS)
• Physical/logical configuration (physical source port or VLAN association)
In the event that a given packet matches two or more grouping criteria, there is a predetermined
precedence for which traffic grouping will apply. In general, the more specific traffic grouping takes
precedence. By default, all traffic groupings are placed in the QoS profile Qp1. The supported traffic
groupings are listed in Table 21. The groupings are listed in order of precedence (highest to lowest). The
four types of traffic groupings are described in detail on the following pages.
Qp2 Q1 Lowhi 0 0% 100%
Qp3 Q2 Normal 0 0% 100%
Qp4 Q3 Normalhi 0 0% 100%
Qp5 Q4 Medium 0 0% 100%
Qp6 Q5 Mediumhi 0 0% 100%
Qp7 Q6 High 0 0% 100%
Qp8 Q7 Highhi 0 0% 100%
