Receiver Configuration

◆

Owner – sFlow can be configured in two ways: Through local

management using the Web 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 shows

■

If sFlow is currently configured through the Web, Owner shows

■

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 can be used to release the current owner and

disable sFlow sampling. This button is disabled if sFlow is currently

unconfigure. If configured through SNMP, the release must be

confirmed (a confirmation request will appear).

◆

IP Address/Hostname – The IP address or host name of the sFlow

receiver. Both IPv4 and IPv6 addresses are supported.

◆

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)
