OLICY MPLEMENTATION
ExtremeWare 5.0, and thus ExtremeWare Enterprise Manager, supports three policy
implementation types. The implementation type of a policy is primarily determined by
the type of endpoints to which the policy will apply.
The implementation types are:
• IP QoS: This uses IP addresses, or IP addresses plus Layer 4 ports, to define the
sources and destinations of the traffic. All Client/Server policies, one direction of an
Application Server policy, and Custom policies are implemented using IP QoS.
• Source Port QoS: This uses switch ports to define the sources of the traffic. Source
Port policies, and the other direction of an Application Server policy, are
implemented using Source Port QoS.
• VLAN QoS: This uses VLANs to define the sources and destinations of the traffic. A
VLAN policy is implemented using the VLAN QoS mechanism.
You do not specify the implementation type—it is defined by the type and components
of the policy you define.
Source Port QoS depends on 802.1Q tagging to carry the QoS parameters
Note:
across switch boundaries, and VLAN QoS depends on tagging to carry QoS
parameters across VLAN boundaries. To allow these QoS types to be effective
end-to-end, you should make sure your switch-to-switch links use tagged ports.

OLICY COPING
A policy may apply to the entire network (default behavior), or may be scoped to apply
only to a portion of the network, by including and excluding device groups. In
addition, treatments can have different parameters for different device groups. You
specify the scoping when you create or modify a policy.

OLICY UTO ONFIGURATION
The ExtremeWare Enterprise Manager Policy System supports auto-configuration of
QoS policies. If Automatic Configuration is turned on every change you make within
the ExtremeWare Enterprise Manager will trigger an immediate re-computation and
reconfiguration of the QoS policies on your network. Configuration changes on a device
managed by ExtremeWare Enterprise Manager, or a user login or end station reboot
when DLCS is enabled, also trigger a recomputation and reconfiguration of QoS
policies.
