Previously, IP multicast high-volume stream start-up could result in a small amount of IP multicast traffic loss. This enhancement provide lossless IP multicast stream startup to existing subscribers, provided that the stream rate does not exceed the slowpath capacity of the switch.
Summit X450-G2, X460-G2, X670-G2, and ExtremeSwitching X440-G2, X465, X590, X620, X690, X870 series switches.
This enhancement applies only to “source-group-vlan” ipmc lookup-key mode (as seen in show forwarding configuration). If another mode is configured (for example, mac-vlan mode), the behavior should be unaffected.
