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.
