sflow sampling Use the sflow sampling command to enable a new sflow sampler instance for this data source if rcvr_idx is valid. An sflow sampler collects flow samples to send to the receiver. Use the "no" form of this command to reset sampler parameters to the default. Syntax sflow rcvr-index sampling {gigabitethernet | tengigabitethernet | fortygigabitethernet} interface-list sampling-rate [size] no sflow rcvr-index sampling {gigabitethernet | tengigabitethernet | fortygigabitethernet} interface-list • rcvr-index-The sFlow Receiver for this sFlow sampler to which flow samples are to be sent. If no receiver is configured, then no packets will be sampled. Only active receivers can be set. If a receiver times out, then all samplers associated with the receiver will also expire. (Range: 1-8). • interface-list - The list of interfaces to poll in unit/slot/port format. • sampling-rate-The statistical sampling rate for packet sampling from this source. A value of n means that out of n incoming packets, 1 packet will be sampled. (Range: 1024-65536). • size-The maximum number of bytes that should be copied from the sampler packet (Range: 20-256 bytes). Default Configuration There are no samplers configured by default. The default is no default sampling rate. The default size is 128. Command Mode Global Configuration mode. User Guidelines Lower sampling numbers cause more samples to be collected and increase the load on the CPU. Setting a sampling rate of 1024 on a large number of ports may tax the CPU beyond it's ability to deliver the packets to the receiver. Switch Management Commands 2242
