Multicast Traceroute e Multicast Traceroute is supported only on platform: MTRACE is an IGMP-based tool that prints that network path that a multicast packet takes from a source to a destination, for a particular group. FTOS has mtrace client and mtrace transmit functionality. • MTRACE Client-an mtrace client transmits mtrace queries and prints out the details received responses. • 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.

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 454.
