The following QoS features are available: • Policy-based QoS-Classifying, rate policing, and marking ingress traffic • WRED • Refer also to Allocate More Buffer Memory for Multicast WRED. Optimize the E-Series for Multicast Traffic e Optimize the E-Series for Multicast Traffic is supported only on platform: The default hardware settings for the E-series are for unicast applications like data centers and ISP networks. This means that the E-Series gives priority to unicast data forwarding rather than multicast data forwarding. For multicast intensive applications like trading, Dell Force10 recommends reconfiguring some default settings. You may do one or more for the following to optimize the E-Series for your multicast application: • Tune the Central Scheduler for Multicast • Allocate More Buffer Memory for Multicast WRED • Allocate More Bandwidth to Multicast using Egress WFQ Multicast Features | 641
