Brocade FastIron Ethernet Switch Administration Guide - Manual (Page 256)

Enabling the sFlow agent to export CPU-directed data
To enable the sFlow agent on a Brocade device to export data destined to the CPU to the sFlow
collector, enter the following command.
device(config)# sflow export cpu-traffic
Syntax: [no] sflow export cpu-traffic
By default, this feature is disabled. The sFlow agent does not send data destined to the CPU to the
sFlow collector.
Specifying the sampling rate for exported CPU-directed data
The sampling rate is the average ratio of the number of packets incoming on an sFlow-enabled port, to
the number of flow samples taken from those packets. You can optionally set the sampling rate for
CPU-directed data exported to the sFlow collector. For example, to set this sampling rate to 2048,
enter the following command.
device(config)# sflow export cpu-traffic 2048
Syntax: [no] sflow export cpu-traffic
The default sampling rate depends on the Brocade device being configured. Refer to Changing the
sampling rate on page 249 for the default sampling rate for each kind of Brocade device.
Displaying sFlow information
To display sFlow configuration information and statistics, enter the following command at any level of
the CLI.
