Syntax

content_copy zoom_out_map
show pfe sFlow egress-mcast-stats

Description

Displays sFlow egress multicast sampling related statistics from the packet forwarding Engine. Dropped samples are the samples exceeding the maximum replication rate. When the router reaches 1990 replications of packets per second with the maximum being 2000 replications along with one packet for the multicast group with 20 replications (20 access side ports part of the multicast group), then since the total is greater than 2000 replications, this packet from the router will be dropped and the dropped samples will be incremented by 1.

When the router samples both unicast and multicast traffic with 1990 unicast and 10 multicast packets, in this case, we will replicate 10 samples with 5 (5 access side ports are part of that group), and the collector will receive 2040 samples.
