• MTRACE Transit-when a Dell Force10 system is an intermediate router between the source and destination in an MTRACE query, FTOS computes the RPF neighbor for the source, fills in the request, and forwards the request to the RPF neighbor. While computing the RPF neighbor, static mroutes and mBGP routes are preferred over unicast routes. When a Dell Force10 system is the last hop to the destination, FTOS sends a response to the query. Task Command Syntax Print the network path that a multicast packet takes from a multicast source to receiver, for a particular group. mtrace multicast-source-address multicast-receiver-address multicast-group-address Figure 30-8.

The following QoS features are available: • Policy-based QoS-Classifying, rate policing, and marking ingress traffic • WRED • See also Allocate More Buffer Memory for Multicast WRED on page 676. 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 on page 676 Multicast Features | 675
