Notes:

  • sFlow can be configured via the CLI for up to three distinct sFlow instances: once enabled, an sFlow receiver/destination can be independently configured for full flow-sampling and counter-polling.
  • CLI-configured sFlow instances may be saved to the startup configuration to persist across a switch reboot.

Configuration steps (CLI)

  1. Define sFlow receiver/destination
sflow <receiver-instance> destination <ip-address> [< udp-port-num >]

Enables a sFlow receiver/destination. The receiver-instance number must be a 1, 2, or 3. By default, the UDP destination port number is 6343.

  1. Enable flow sampling
sflow <receiver-instance> sampling <port-list> <sampling rate>

Once a 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 skip count 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.

  1. Enable counter polling
sflow <receiver-instance> polling <port-list> <polling interval>

Once a 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.
