A QoS profile does not alter the behavior of the switch until it is assigned to a
traffic classification.
The details of the default profiles are shown in Table 8-1.
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.
T RAFFIC G ROUPINGS
Different traffic groupings are available, depending on the QoS mode configured for the
switch. 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.
I NGRESS T RAFFIC G ROUPINGS
Ingress traffic groupings include the following:
• IP destination address — A specific QoS profile can be associated with an IP
destination address, or range of IP destination addresses specified using a subnet
mask. The QoS parameters are dynamically associated with a route when the route
table is built. This is controlled by the following command:
config ipqos [add | delete] <ip_destination_address>/<mask_length>
qosprofile <qosname>
Table 8-1: 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%
