Basically, 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
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, 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 button is disabled if sFlow is currently unclaimed. If configured
through SNMP, the release must be confirmed (a confirmation request appears).
The IP address or hostname of the sFlow receiver. Both IPv4 and IPv6 addresses are
supported.
The UDP port on which the sFlow receiver listens to sFlow datagrams. If set to 0
(zero), the default port (6343) is used.
The number of seconds remaining before sampling stops and the current sFlow owner
is released. While active, the current time left can be updated by clicking the Refresh
button. If locally managed, the timeout can be changed on the fly without affecting
any other settings.
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.
The port number for which the configuration below applies.
Enables/disables flow sampling on this port.
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 MP1204-XT automatically adjusts it to the closest achievable. This is reported
back in this field.
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.
Enables/disables counter polling on this port.
