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

The default is no default sampling rate.
The default size is 128.
