 Max. Datagram Size
The maximum number of data bytes that can be sent in a single sample datagram.
This should be set to a value that avoids fragmentation of the sFlow datagrams.
Valid range is 200 to 1468 bytes with default being 1400 bytes.
Port Configuration
 Port
The port number for which the configuration below applies.
 Flow Sampler Enabled
Enables/disables flow sampling on this port.
 Flow Sampler Sampling Rate
The statistical sampling rate for packet sampling. Set to N to sample on average
1/Nth of the packets transmitted/received on the port.
Not all sampling rates are achievable. If an unsupported sampling rate is
requested, the switch will automatically adjust it to the closest achievable. This
will be reported back in this field.
 Flow Sampler Max. Header
The maximum number of bytes that should be copied from a sampled packet to
the sFlow datagram. Valid range is 14 to 200 bytes with default being 128 bytes.
If the maximum datagram size does not take into account the maximum header
size, samples may be dropped.
 Counter Poller Enabled
Enables/disables counter polling on this port.
 Counter Poller Interval
With counter polling enabled, this specifies the interval - in seconds - between
counter poller samples.
