ONFIGURATIONS
A QoS policy is determined by one or more of the following building blocks:
•QoS mode — Indicates whether the switch should use egress or ingress traffic
classifications. Ingress is the default.
• QoS profile — Includes bandwidth and priority parameters.
• Traffic classification —A method of grouping traffic that has one or more attributes
in common.
ExtremeWare lets you manage QoS policy on a number of traffic classifications
—VLAN-based, destination MAC-based, IP-based, and so on. In the 1.0 release,
ExtremeWare Enterprise Manager supports only the VLAN-based traffic classification.

ROFILES
The ExtremeWare Enterprise Manager supports the four default QoS profiles as defined
for Summit switches, as well as custom profiles you create.
The parameters that make up a QoS profile include:
• Minimum bandwidth — The minimum percentage of bandwidth that the traffic
requires. The switch is required to provide the minimum amount of bandwidth to
the traffic. The range of values is between 0% and 100%.
• Maximum bandwidth — The maximum percentage of bandwidth that the traffic is
permitted to use. The range of values is between 0% and 100%.
•Priority — The level of priority in which the traffic will be serviced by the switch.
Choices include:
— Low
— Normal
— Medium
— High
