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.
Valid range is 1 to 4294967295.
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. Valid range is 1 to 3600 seconds.
