sFlow Version 5

sFlow version 5 enhances and modifies the format of the data sent to the sFlow collector. sFlow version 5 introduces several new sFlow features and also defines a new datagram syntax used by the sFlow agent to report flow samples and interface counters to the sFlow collector.

sFlow version 5 supports the following modifications:

• sFlow version 5 datagrams
• Sub-agent support
• Configurable sFlow export packet size
• Support for the new data field and sample type length in flow samples
• Configurable interval for exporting RUCKUS-specific data structures

sFlow version 5 is backward-compatible with sFlow version 2. The sFlow agent exports sFlow version 5 flow samples by default, but you can configure the device to export the data in sFlow version 2 format. You can switch between the sFlow version 2 and sFlow version 5 formats. The sFlow collector automatically parses each incoming sample and decodes it based on the version number.

The configuration procedures for sFlow version 5 are the same as for sFlow version 2, except where explicitly noted. For configuration procedures for sFlow, refer to Configuring sFlow. The features and CLI commands that are specific to sFlow version 5 are described in sFlow version 5 feature configuration.
