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
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% |

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.
TRAFFIC GROUPINGS
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.
INGRESS TRAFFIC GROUPINGS
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>
