MCLAG is a control plane function. Sflow on devices that don't generate it in a distributed fashion is done but punting sampled packets to the control-plane for classification by an sflow agent. Sample rate is therefore contingent on adequate CPU and control-plane bandwidth. The greyhound switch SOC may be hampered by the amount of CPU available locally, but the 2MB packet buffer also is probably cause for caution. > https://www.broadcom.com/products/ethernet-connectivity/switch-fabric/bcm5341x/ > > > > > > ----- > Mike Hammett > Intelligent Computing Solutions > > Midwest Internet Exchange > > The Brothers WISP > >
