HP ProCurve switches are currently designed so that sFlow is enabled remotely by an sFlow collector – the CCE.
Example HP ProCurve sFlow configuration:
The following example was published in the context of a switch that had at least 55 ports installed. For the sake of this example, the IP address was 15.29.16.93.
STEP 1: Set the destination IP (The IP of the collector station--Note that the IP Address is in hex but without the leading 0x):
setmib sFlowRcvrAddress.1 -o 0F1D105D
For reference, here is an IP to HEX converter:

STEP 2: Set the traffic destination port number
Destination port 996 (Default value is 6343)
setmib sFlowRcvrPort.1 -i 996
STEP 3: Enable Receiver
setmib sFlowRcvrOwner.1 -D Name sFlowRcvrTimeout.1 -i 100000000
STEP 4: Set flow sampling rate
Port 53, sampling rate of 37:
setmib 1.3.6.1.4.1.14706.1.1.5.1.4.11.1.3.6.1.2.1.2.2.1.1.53.1 -i 37
Port 55, rate of 20:
setmib 1.3.6.1.4.1.14706.1.1.5.1.4.11.1.3.6.1.2.1.2.2.1.1.55.1 -i 20
Port 5, rate of 20:
setmib 1.3.6.1.4.1.14706.1.1.5.1.4.11.1.3.6.1.2.1.2.2.1.1.5.1 -i 20
(Note: Some switches require a sample rate of at least 50)
STEP 5: Set Enable to True (1), Per Port
Port 53: setmib 1.3.6.1.4.1.14706.1.1.5.1.3.11.1.3.6.1.2.1.2.2.1.1.53.1 -i 1
Port 55: setmib 1.3.6.1.4.1.14706.1.1.5.1.3.11.1.3.6.1.2.1.2.2.1.1.55.1 -i 1
Port 5: setmib 1.3.6.1.4.1.14706.1.1.5.1.3.11.1.3.6.1.2.1.2.2.1.1.5.1 -i 1
STEP 6: Set the counter polling interval, Per Port
Interval of 8 seconds,
port 53: setmib 1.3.6.1.4.1.14706.1.1.6.1.4.11.1.3.6.1.2.1.2.2.1.1.53.1 -i 8
Interval of 7 seconds, port 55: setmib 1.3.6.1.4.1.14706.1.1.6.1.4.11.1.3.6.1.2.1.2.2.1.1.55.1 -i 7
Interval of 50 seconds, port 5: setmib 1.3.6.1.4.1.14706.1.1.6.1.4.11.1.3.6.1.2.1.2.2.1.1.5.1 -i 50
If needed:
Disabling: To kill all sampling and to release the receiver just set timeout to 0:
setmib sFlowRcvrTimeout.1 -i 0
