Configuring sFlow (CLI)

The following sFlow commands allow you to configure sFlow instances via the CLI. For more information, see Advanced management: RMON.

Syntax:


no sflow <receiver-instance> 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.

Syntax:


sflow <receiver-instance> 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.

To disable flow-sampling for the specified port-list, repeat the above command with a sampling rate of 0.

Syntax:


sflow <receiver-instance> 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.

To disable counter-polling for the specified port-list, repeat the above command with a polling interval of 0.

NOTE:

Under the multiple instance implementation, sFlow can be configured via the CLI or via SNMP. However, CLI-owned sFlow configurations cannot be modified via SNMP, whereas SNMP-owned instances can be disabled via the CLI using the no sflow <receiver-instance> command.
