• QoS Policy Flow - A QoS Flow refers to a sub-stream of packets on a port that satisfies a set of classification conditions.
For example, a stream of packets classified by the condition that their destination TCP port is 80 (i.e., TCPDPORT=80) is
considered a QoS Flow.
• QoS Priority Action - A QoS Priority Action is to take a QoS Policy Flow and to prioritize it according to the 802.1
VLAN priority fields or the IP DSCP/TOS fields.
• QoS Traffic Action - A QoS Traffic Action refers to policing/conditioning of a flow, such as limiting the maximum
bandwidth or guaranteeing a minimum bandwidth.
• QoS Policy Rule - A QoS Policy Rule is the association of a Flow, Priority Action, and Traffic Action. To apply traffic
conditioning to aggregate flows, where the individual flows have different priorities, multiple flow-priority pairs can be
entered with a single Traffic Action.
Note: The NMS will only allow traffic conditioning on multiple flows if all of the Target Device Classes specified support this
capability.
• QoS Policy - A QoS Policy is the result of combining the QoS Policy Rules into a set so that, taken as a whole, it can be
applied to a port or set of ports.
Note: There are restrictions for policy names, as explained in more detail later.
