Configure an sFlow Receiver

Use sFlow receivers to provide visibility into your switch traffic patterns. Configure sFlow receivers as common objects that you can assign to specific devices. Use the following procedure to configure an sFlow receiver as a common object.

  1. Go to Configure > Common Objects > Network > sFlow Receivers.
  2. Select an existing sFlow Receiver, and then select Edit, or select Add, and then select Switch from the menu.
  3. Type a Name.
  4. Type an optional Description.
  5. Type the IP address of the receiver, to which the accumulated data will be sent.
  6. Select a UDP Port Number.

    This is the UDP port number of the sFlow receiver where the data will be sent. The default UDP port number is 6343. (Range: 1-65535).

  7. Select a Maximum Datagram Size.

    This is the maximum number of data bytes that can be sent in a single sFlow diagram. Select a value that avoids datagram fragmentation.

  8. The Owner String is an identity string required for the sFlow receiver configuration to take affect.

    This is usually the same as the receiver name.

  9. Select a timeout value.

    This is the time, in seconds, before the sFlow sampler stops sending data to the receiver. A zero receiver timeout displays the sFlow receiver configuration in the running config.

  10. Select a sampling rate (number of packets) and sample size (in bytes).

    A higher sampling rate lowers the CPU burden on the device, and helps ensure that all collected samples can be sent to the receiver.

  11. Select an interval for the sFlow receiver.
  12. Select SAVE SFLOW RECEIVERS.

    You can delete a single sFlow receiver or multiple receivers. Select the corresponding check boxes for the receivers and then select the delete icon.

    You can add a new sFlow receiver by creating a clone of an existing receiver and then renaming it. Select the check box for the sFlow receiver that you want to clone and then select the clone icon. Type the new Name and then select Clone.
