QoS is a feature of Summit switches that allows you to specify different service levels
for outbound traffic. QoS is an effective control mechanism for networks that have
heterogeneous traffic patterns. Using QoS, you can specify the service that a traffic type
receives.
The main benefit of QoS is that it gives you control over the types of traffic that receive
enhanced service from the switch. For example, if video traffic requires a higher priority
than data traffic, you can use QoS to assign a different QoS profile to those VLANs that
are transmitting video traffic.
The ExtremeWare Enterprise Manager lets you create custom QoS profiles that are
available to all Summit switches known to the Enterprise Manager database. You can
apply these profiles as QoS policy for any VLAN defined within the Enterprise
Manager.
