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 expires, 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. 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).
