sFlow Interface Configuration
sFlow agent collects statistical packet-based sampling of switched flows and sends them to
the configured receivers. A data source configured to collect flow samples is called a
sampler. sFlow agent also collects time-based sampling of network interface statistics and
sends them to the configured sFlow receivers. A data source configured to collect counter
samples is called a poller.

sFlow Interface Configuration.
1. Interface - Interface for this flow poller and sampler. This Agent will support Physical
ports only.
2. Use Receiver Index to specify the allowed range for the sFlowReceiver associated with this
counter poller. Allowed range is 1 to 8.
3. Use Poller Interval to specify the maximum number of seconds between successive
samples of the counters associated with this data source. A sampling interval of 0 disables
counter sampling. Allowed range is 0 to 86400 secs.
4. Use Receiver Index to specify the sFlow Receiver for this flow sampler. If set to 0, the
sampler configuration is set to default and the sampler is deleted. Only active receivers can
be set. If a receiver expires then all samplers associated with the receiver will also expire.
Allowed range is 1 to 8.
5. Use Sampling Rate to specify the statistical sampling rate for packet sampling from this
source. A sampling rate of 1 counts all packets. A sampling rate of 0 disables sampling.
Allowed range is 1024 to 65536.
6. Use Maximum Header Size to specify the maximum number of bytes that should be copied
from a sampled packet. Allowed range is 20 to 256.
