sFLOW Configuration Parameters:
Items Description
Agent Configuration
IP Address
This IP address is used as Agent IP address in sFlow datagrams. It serves as a unique key that
will identify this agent over extended periods of time. Both IPv4 and IPv6 addresses are
supported.
Receiver Configuration
Owner
sFlow can be configured in two ways. Through local management using the Web or CLI
interface or through SNMP. This read-only field shows the owner of the currently sFlow
configuration and assums calues as flollows:

If sFlow is currently unconfigured/unclaimed, Owner contains <none>.

If sFlow is currently configured through Web or CLI, Owner contains <Configured
through local management>

If sFlow is currently configured through SNMP, Owner contains a string identifying the
sFlow receiver.

If sFlow is configured through SNMP, all controls – except for the Release button are
diesabled to avoid inadvertent reconfiguration. The button allows for releasing the
current owner and disable sFlow sampling. The button is disabled if sFlow is currently
uclaimed. If configured through SNMP, the release must be confirmed (a confirmation
request will appear).
IP Address/Host name The IP address or hostname of the sFlow reciever. Both IPv4 and IPv6 addresses are supported.
UDP Port The UDP port on which the sFlow receiver listens to sFlow datagrams. If set to 0 (zero), the
default port (6343) is used.
Timeout The number of seconds remaining before sampling stops and the current sFlow owner is
released. While active, the current time left can be updated with a click on the Refresh-button. If
locally managed, the timeout can be changed on the fly without affecting any other settings.
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 1488
bytes with default being 1400 bytes.
Port Configuration
Port
The port nmber for which the configuration below applies.
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.
