•Priority — The level of priority in which the traffic will be serviced by the switch.
Choices include:
— Low
— Normal
— Medium
— High
A QoS profile does not alter the behavior of the BlackDiamond until it is assigned
to a traffic classification.
The details of the default profiles are shown in Table 7-1.
You can modify the minimum and maximum bandwidth parameters of the default QoS
profiles in either ingress or egress mode. The priority parameter can not be modified in
ingress mode.

ROUPINGS
Different traffic groupings are available, depending on the QoS mode configured for the
system. In the event that a given packet matches two or more grouping criteria, there is
a predetermined precedence for which traffic grouping will apply. By default, all traffic
groupings are placed in the QoS profile named qp1.
The available traffic groupings are listed in the following sections, in order of highest to
lowest precedence.
Table 7-1:
Default QoS Profiles
Profile Name Priority Minimum Bandwidth Maximum Bandwidth
qp1 Low 0% 100%
qp2 Normal 0% 100%
qp3 Medium 0% 100%
qp4 High 0% 100%
