Configuring sFlow
– 216 –
◆
UDP Port – The UDP port on which the sFlow receiver is listening for
sFlow datagrams. If set to 0 (zero), the default port (6343) is used.
(Range: 0-65534; Default: 6343)
◆
Timeout – The number of seconds remaining before sampling stops,
the current sFlow owner is released, and all sFlow parameters are
reset. (Range: 0-9999999 seconds, where 0 indicates no time out)
The sFlow parameters affected by this command include the IP address
and UDP port, timeout, maximum datagram size, sampling rate, and
maximum header size.
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.
◆ Max. Datagram Size – Maximum size of the sFlow datagram payload.
This should be set to a value that avoids fragmentation of the sFlow
datagrams. (Range: 200-1468 bytes; Default: 1400 bytes)
Port Configuration
◆ Port – Port identifier.
◆ Flow Sampler – The following parameters apply to flow sampling:
■
Enabled – Enables/disables flow sampling on this port.
■
Sampling Rate – The number of packets out of which one sample
will be taken. (Range: 1-4096 packets, or 0 to disable sampling;
Default: Disabled)
■
Max. Header – Maximum size of the sFlow datagram header.
(Range: 14-200 bytes; Default: 128 bytes)
If the maximum datagram size does not take into account the
maximum header size, samples may be dropped.
◆ Counter Poller – The following parameters apply to the counter:
■
Enabled – Enables/disables counter polling on this port.
■
Interval – The interval at which the counters are updated.
(Range: 0-3600 seconds, where 0 disables this feature;
Default: Disabled)
