Configuring sFlow

[no] sflow <instance-Nr.> destination <ip-address> [udp-port-num]

Enables an sFlow receiver/destination. The receiver-instance number must be a 1, 2, or 3.
By default, the udp destination port number is 6343.
To disable an sFlow receiver/destination, enter no sflow receiver-instance.


sflow <instance-Nr.> sampling <PORT-LIST> sampling <rate>

Once an sFlow receiver/destination has been enabled, this command enables flow sampling for that instance.
The receiver-instance number is 1, 2, or 3, and the sampling rate is the allowable non-zero skipcount for the specified port or ports.
A good starting point for sampling rate is 500 on high volume switches rais this value to 2000 or 5000.

To disable flow-sampling for the specified <PORT-LIST> repeat the above command with a sampling rate of 0.


sflow <instance-Nr.> polling <PORT-LIST> polling <interval>

Once an sFlow receiver/destination has been enabled, this command enables counter polling for that instance.
The receiver-instance number is 1, 2, or 3, and the polling interval may be set to an allowable non-zero value to enable polling on the specified port or ports.
A good starting point for polling interval is 20.

To disable counter-polling for the specified <PORT-LIST>, repeat the above command with a polling interval of 0.

sFlow on ProCurve 2610

Shamelessly stolen from: https://thwack.solarwinds.com/thread/23881


For a HP Procurve 2610 sflow needs to be enabled. You do this by modifying mib variables.
Red items are variables you need to change. Notes on Red Items below


The following needs to be run in config mode:


setmib sFlowRcvrAddress.1 -o c0a80001
                             ^---- The IP address of the receiver in HEX

setmib sFlowRcvrPort.1 -i 2055
                          ^---- Listen-Port of the receiver server

setmib sFlowRcvrOwner.1 -D OwnerName sFlowRcvrTimeout.1 -i 214748364


setmib sFlowFsPacketSamplingRate.11.1.3.6.1.2.1.2.2.1.1.1.1 -i 37
setmib sFlowFsPacketSamplingRate.11.1.3.6.1.2.1.2.2.1.1.2.1 -i 37
setmib sFlowFsPacketSamplingRate.11.1.3.6.1.2.1.2.2.1.1.3.1 -i 37
setmib sFlowFsPacketSamplingRate.11.1.3.6.1.2.1.2.2.1.1.4.1 -i 37
                                                        ^--- This one is the Switchport to set Sampling Rate on

setmib sFlowFsReceiver.11.1.3.6.1.2.1.2.2.1.1.1.1 -i 1
setmib sFlowFsReceiver.11.1.3.6.1.2.1.2.2.1.1.2.1 -i 1
setmib sFlowFsReceiver.11.1.3.6.1.2.1.2.2.1.1.3.1 -i 1
setmib sFlowFsReceiver.11.1.3.6.1.2.1.2.2.1.1.4.1 -i 1
                                              ^---- This one is the Switchport to set the ENABLE Bit on

sFlowRcvrAddress is the hex IP address for the NetFlow Server.

sFlowRcvrPort is the port that Netflow is received on on the NetFlow server. Note: 2055 is default.

sFlowRcvrOwner is the owner tag in show sflow destination as far as I can tell it is simply descriptive.

sFlowRcvrTimeout is the amount of time to transmit sflow data to the destination. sflow will stop after this timer runs out. 214748364 = ~6.8 years.

The numbers highlighted in the mib variable strings are the ports that the variables are set on.

sFlowFsPacketSamplingRate is the packet sampling rate the faster the sampling the more accurate the data (and likely the slower the packet transfer from the overhead).

sFlowFsReceiver is the sflow enable bit.
