Protocol traffic analysis.
Maximum number of sFlow instances.
SFlow support on LAG ports.

Although the switch hardware has the capability to sample packets on any physical port (not LAG ports); to ensure that CPU utilization is not compromised, the number of sFlow samplers that can be configured per switch or stack of switches is limited to a maximum of 32. There is no limitation on the number of pollers that can be configured.

This means that Flow Sampling ('set sflow sampler...') is limited to a maximum of 32 ports per system (violation: "Incorrect input! Maximum Samplers Limit(32) exceeded."), while Counter Sampling ('set sflow poller...') is not port-limited.
