I wouldn't put it past measuring error. Is 10-15ms expected? I.e. this is like 1000km? However based on just information available, perhaps flows timeout periodically and hit the control-plane. I think SUP2T like PFC3 before it punts all mcast, then programs flow in HW, then subsequently hardware format it. If so, perhaps you can tune with multicast flow timers. > - what I can use to try to decode pcap taken on Arista switch to check if > the latency is really obtained checking protocol market timestamp ? Several samples, coffee and time. -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
