www.dell.com | support.dell.com As an Mtrace transit or intermediate router, FTOS returns the response to Mtrace queries. Upon receiving the Mtrace request, FTOS computes the RPF neighbor for the source, fills in the request and the forwards the request to the RPF neighbor. While computing the RPF neighbor, the static mroute and mBGP route is preferred over the unicast route. multicast-buffering enable Enable buffering for all multicast traffic on the buffering unit. Syntax [no] multicast-buffering enable Command Modes CONFIGURATION Command History Version 8.3.3.8 Introduced on S60. Usage Information Use this command to enable backpressure messages for multicast traffic and allow the system to start buffering multicast traffic. If multicast traffic is buffered for one group on any port, all multicast, Destination Lookup Failure (DLF) and broadcast traffic is buffered. Note that multicast packets might be dropped if either of the following occurs: • continuous oversubscription at the egress • if the packet is not drained for a long period because of slow draining rate at the egress port compared to high ingress rate. You must reboot the switch to enable the command on a standalone unit. Buffering multicast units is not supported on stacked units.
