Parameter descriptions
:
Agent Configuration
IP Address
: The IP address used as the 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
: Basically, sFlow can be configured in two ways: 1) via local management using the Web or CLI interface
or 2) via SNMP. This read-only field shows the owner of the current sFlow configuration and assumes values as
follows:
•
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, the Owner contains a string identifying the sFlow
receiver. If sFlow is configured through SNMP, all controls - except for the Release-button - are disabled
to avoid inadvertent reconfiguration.
The Release button allows for releasing the current owner and disable sFlow sampling. The Release button is
disabled if sFlow is currently unclaimed. If configured through SNMP, the release must be confirmed (a
confirmation request will display).
IP Address/Hostname
: The IP address or hostname of the sFlow receiver. 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. The valid range is 200 to 1468
bytes and the default is 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 consider 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.
